This tutorial provides solutions for improving the security of Android devices.How to Secure your Android smartphone? what is best solution to make your files and applications secure?

Today’s smartphones receive extensive and sensitive information from their users, the most important of which are user account data, emails, bank information, images, videos, etc. Unfortunately, Android devices have severe weaknesses in terms of security and are considered a suitable target for malware, spyware and ransomware. In this article, we will mention some practical tips to improve the safety of Android phones, which can help protect privacy and data protection.

How to Secure your Android phone

Devices based on the Android operating system account for 70% of the global smartphone market. Still, despite the high popularity, Google and the manufacturing companies have not been able to provide security for the owners of such products well. Although there has been a particular focus on improving security features in recent versions of Android, Apple products like iPhone are still much more secure.
The weak security of Android devices has caused users to take preventive measures. These can include using security applications, paying more attention to installing programs or visiting website pages. Below are some of the most essential points about this issue.

1. Use two-step authentication

Two-factor authentication is one of the best ways to secure user accounts. Many services compulsively provide this feature to their users, while others still offer it as optional. There are various methods for two-step authentication, among the most popular of which you can mention sending a verification code via SMS, email, or specific applications.

Because most of the information on Android devices is stored on the Google account, we recommend you enable two-step authentication. Of course, if you are interested, you can activate the mentioned feature for other services, such as Samsung or Xiaomi accounts. The Google Authenticator app is one of the best apps to take advantage of the said feature, which is free for users.

2. Download programs from reliable sources

Many malware is installed in the form of malicious applications on Android devices with the user’s permission, While their appearance indicates a simple game or tool. Of course, users can reduce the possibility of such an occurrence by downloading the application only from reliable and official sources, in addition to preventing the installation of the application from other sources.

The best source for downloading Android applications is Google Play, But users can also use other stores such as Galaxy Store or Mi Store. Of course, there is also the possibility of malware in these resources; But compared to app download sites, it is less. Cracked programs can also be considered a significant security risk, But due to the lack of access to international payments in Iran, most users have no choice but to use such titles.

3. Improving the security of Android phones with antivirus

Although Google Play uses an internal scanning engine to check and find infected applications, users can also go to mobile antivirus programs for more certainty. Of course, most of these programs do not provide much exceptional functionality, and users who observe the security issues correctly will not need a mobile antivirus.
Famous and reliable antiviruses such as Norton, Bitdefender and McAfee also have versions for Android, some of which are free with limited features. Also, if you care about your security while surfing the web and using online tools, you can use the Sophos Intercept X application, which is free.

4. Activate the Find My Device feature

Android’s Find My Device feature allows users to remotely control their phone or tablet and erase the data if needed. This feature can be helpful when the device is stolen or lost and protects users’ data.

Just follow the steps below to activate the said feature on Samsung devices.

  • First, enter the Settings section of your mobile phone or tablet and then refer to the Biometrics and security section.
  • Click on the Find My Mobile option, and then on the opened page, activate the top button.
  • Next, activate the Remote unlock and Send the last location options, which are used to remotely lock the device and send the location.

5. Manage application access

secure android

Applications installed on Android devices require different types of access to function properly. These accesses can include sensitive things such as reading and writing information on the internal memory, viewing calls and text messages, accessing the contact list, etc. Fortunately, obtaining such access without user approval is impossible, but people can grant access without much consideration.

It is better to check the access list after installing them. For example, an offline game will not need to see text messages or make calls; if there is such an option, you should suspect it. Google Play uses the internal feature to remove access to unused programs, which you can activate through the following path.
Android phone security

  • First, enter Google Play and then click on your profile icon in the upper corner of the screen.
  • Next, select the Play Protect option and go to the Settings section.
  • On the settings page, click on the Permissions for new apps option, and after selecting the desired application, set the key in the middle of the screen to active mode.

6. Avoid rooting the device

Many Android users root their devices to benefit from more applications or features related to personalization. Although rooting alone does not harm the security of Android phones and tablets, apps with root access can have much more control over the device’s performance, which is dangerous in some cases. Security researchers emphasize that rooted devices are more likely to be infected with malware; As a result, users should avoid rooting them.

7. Not connecting to insecure and anonymous networks

Publicly available wireless network hotspots have always been considered one of the biggest security threats. Such networks usually have low security; As a result, they can be used for unauthorized access to other people’s data.

The Biography of Pavel Durov

Russian Mark Zuckerberg, home of the tech world in self-imposed exile with a reclusive spirit and all-black outfits to pay homage to the movie The Matrix. These are the terms used to describe Pavel Durov, the founder of the Telegram messenger; The man who revolutionized the Russian Internet by founding the VKontakte social network, stood up against government pressure, and became an angel of user privacy and data security with his libertarian beliefs.

Pavel Durov is not a fan of interviews and is rarely talked about in the media. If you want to know more about the life of this mysterious and rebellious character, follow this article.

The story of a rebellious entrepreneur

Pavel Durov, the founder of the Russian social network VKontakte, was sitting alone in his apartment in St. Petersburg when a group of men in uniform and armed with guns knocked on his door. Pavel quietly approached the door and peered into the corridor. Then he went to the window and saw many of them standing outside the building. He decided not to open the door and ignored the shouts behind the door calling his name. Then his phone rang and unknown numbers called him one after another. Powell did not return any of these calls.

Powell knew why the officers had come to his house. A few days earlier, he had received a letter from the Federal Security Service of the Russian Federation (FSB), a CIA-like organization, asking him to remove pages on VKontakte that were used to organize popular protests.

But Powell not only refused to do so, but the day after receiving the letter he upgraded the website to include more posts on each page. On the same day, he posted a photo of the letter along with the image of a dog in a hoodie sticking out its tongue on Twitter and wrote that this was his official response to the request of the FSB.

After an hour of Paul’s indifference, the armed men behind the door finally left the building; But in front of Pavel was a difficult battle that ultimately led to his defeat; Of course, the failure that was the beginning of his entry into the vast and exciting world of messengers and concerns about privacy and user data. If the agents had not come to his house for inspection that day and Durov had not been so involved with the idea of ​​user data security, maybe there would be no trace of Telegram today or it would not exist in the form it is today.

Pavel Durov; Russian Mark Zuckerberg

The VKontakte platform known as VK is the most popular social network in Russia with 500 million user accounts and 90 million monthly visits (2019) and is more popular among Russian users than Facebook and Twitter. Durov launched the social network at the age of 22 and is often compared to Mark Zuckerberg, the founder of Facebook. Both giants of the Internet world were born in 1984, and their serious entry into the world of virtual communication started from their student days.

Banknote rockets later inspired the Telegram icon

Durov avoids the attention of the official media, prefers black and non-luxurious clothes, and steals his gaze from the camera; But when it comes to interacting with people, he is more sociable than his American counterpart. When one of VK’s senior managers received a large bonus, Durov told the other members that he was not in it for the money. Upon hearing this statement, his colleagues asked him to return the money he received if it is true. This person agreed to throw the money out the window. Durov told him that his method of throwing money out was not creative and showed him how to make 5,000 ruble bills (about $70) into paper rockets and then throw them out the window into the street. These banknote rockets later inspired the Telegram icon.

According to Vice, Durov got the idea of ​​creating a social network when a friend who studied in America showed him an early version of Facebook. Thus, VK was launched as a beta in September 2006 and had an official and legal organization in 2007. Even today, the design of this social network looks like the original version of Zuckerberg’s design.

For the first few years, VK was almost a Spotify-style library of all kinds of media, including black-market movies and music. According to Katya Romanovskaya, one of the authors of the satirical Twitter account @KermlinRussia, “almost everything on VK was illegal” in those days.

Tensions begin and Durov says goodbye to VK

Vkontakte social network

When Putin announced his intention to run for re-election in late 2011, opposition groups flocked to VK and organized public protests by publishing news and material against Putin. Even the leader of the opposition party, Alexei Navalny, was the administrator of a VK page with over 100,000 followers, and when the website’s algorithm automatically blocked his page for excessive activity, Durov came to his rescue and changed the website’s algorithm.

VK had the full attention of the FSB intelligence agency. The day government agents knocked on Durov’s door, his rebellious spirit flared up. Durov refused to remove the protest pages and emphasized that VK is a 100% non-political organization and that removing these pages would cause users to migrate from VK and cause a severe financial blow to his team’s business.

The Kremlin left VK alone for a while; But in early 2013, Durov’s troubles began again. In a report, Russian news outlet Novaya Gazeta released several hacked emails between Durov and the Kremlin’s “main ideologist,” Vladislav Surkov, and claimed the VKontakte founder had been working with the FSB for years.

According to the editor of RuNet Echo, many VK users did not believe such a report; But this was only the beginning of the campaign against Dwarf. In April of the same year, a car belonging to Ilya Perkopsky, the chief executive of VK, ran over a police officer. The driver ran away from the scene, But the police claimed that the person behind the wheel was Durov. In response to this accusation, Durov said that he does not know how to drive.

A few days later, police officers began searching VK’s offices in Moscow, according to the Moscow Times. The reason for this inspection was announced as “part of the investigation into the accident and fleeing the scene”. The next day, the two main investors of VK, Vyacheslav Mirilashvili and Lev Lviv, announced their intention to sell their 48% stake. Investors were looking to sell their shares because of the rift between them and Durov, according to multiple sources. According to Interfax, the value of this social network at that time was 2 billion dollars.

Durov fled to Buffalo, New York later that month and began work on his new project, Telegram. The police finally stopped pursuing the accident case.

At that time, 88% of VK shares were held by government supporters and 12% were still held by Durov. Durov announced that he did not intend to sell his shares and his activity on this platform continued until the end of 2013. On his VK page, Pavel wrote about the website’s growth compared to other social networks, including Facebook and WhatsApp, and published an infographic showing that in October 2013, VK was the top Android app in Moscow.

But in January 2014, Durov announced that he had sold his entire 12% stake to the mobile phone operator Megaphone for $300 million. In an interview with Motherboard magazine, he said: “It was clear that my 12% share did not give me much decision-making power, But it could be used to limit my freedom in critical situations.” With Durov selling his shares, VK was now 100% under the financial control of Kremlin allies.

Durov lost his financial investment; But for how long did he remain as the general manager of VK? On April 1, 2014, he finally announced his resignation from the board of directors of VK citing the excessive involvement of new shareholders in the management of the website. Of course, two days later, he claimed that his resignation was April’s lie and tried to withdraw the letter; But the shareholders did not allow him to do this. On April 22, Durov found out that he was officially fired from VK.

Durov was forced to sell his shares due to political pressure and had to say goodbye to the big company he founded forever, But this happened at the right time. He said in an interview with Motherboard:

The Russian Internet market fell dramatically after this incident. In a way, I am grateful to the shareholders and political forces that made me sell my shares. Now I am more satisfied that I can serve the audience on a wider scale than the world.

Personal life of Pavel Durov

Pavel Valerievich Durov was born on October 10, 1984, in Saint Petersburg and grew up in an educated family. Pavel is the second child in the family and has an older brother named Nikolai, who was with him in launching the social network VK and Telegram.

As a child, Pavel had to move to Italy with his family because of his father’s job and studied first grade in the city of Turin. Two years later, the whole family returned to Russia, and after four years of secondary education, Pavel went to the Dmitri Fadeev School of Mathematics and Physics at St. Petersburg State University, where he studied all subjects, including four foreign languages, in-depth.

From the age of 11, Pavel was very interested in programming with his brother. After finishing high school with excellent grades, he studied English language translation at the Faculty of Philosophy of St. Petersburg University.

Pavel Durov speaks 8 languages ​​including Farsi

According to information on Pavel’s official VK page, he speaks eight foreign languages: Russian, English, French, German, Spanish, Italian, Latin and even Farsi. Of course, it is not possible to say how true this information is.

In university, Pavel was one of the best students with a high level of intelligence. He has repeatedly won linguistics, programming, and design olympiads, has received scholarships from the Government of the Russian Federation and the President of the Russian Federation, and is a three-time winner of the Potanin Innovation Award.

While a student, he launched the website, which housed a database of educational materials for humanities students. Then he came up with the idea of ​​another website ( where St. Petersburg University students could communicate with each other through its forum.

On this site, each student had his personal account, which included information such as name, faculty, and list of friends and groups. Any user could also blog on this website. This is how the initial version of the VK social network was born. To promote his website, Powell organized beauty and design contests at the university and sometimes engaged in heated discussions with an anonymous account to create excitement on the website’s forum.

Durov spends most of his time on innovation, self-improvement, and entrepreneurship. Now everyone knows him as the founder of Telegram, which in a way embodies all his ideals in the field of user data security.

Nikolay Durov

We all know Telegram with Pavel Durov; While Pavel’s brother, Nikolai, also played a big role in the formation of this popular messenger.

In fact, Nikolai’s role in the development of all the projects discussed, from the website to this Telegram, is very prominent. He showed interest in natural sciences from his childhood; While Powell’s interest was in the field of humanities. Despite this difference, these two brothers had a common interest and that was programming.

Nikolai, who was a talented programmer, wrote a few lines of code for the VKontakte platform when it was still in the early stages of development, and then, as the popularity of this social network grew, he became more involved in its development and eventually took the position of technical manager and senior developer of the company. Nikolai worked on this platform until 2014 when Pavel resigned from the VK board and took the entire team out of the country with him.

In an interview with Medium, Powell said that his brother played a big role in developing his ideas. He mentions Nikolai as a genius who solved complex mathematical equations quickly in TV competitions, read a lot of books, and came first in almost all math competitions.

Pavel Durov’s residence

Durov left Russia in April 2014 and said he would never return to his homeland. Because the internet rules in this country are not clear it is impossible to do online business there.

Pavel is now a bit of a homebody, traveling around the world with his team of programmers and usually not staying in one country for more than a few months. Since leaving Russia, he has lived in Berlin, London and Singapore.

Currently, he and the Telegram development team live in Dubai. It is written in the FAQ section of Telegram that they are satisfied with life in Dubai; But as soon as the internet laws of this country change, they are ready to change their location.

Pavel Durov’s citizenship

The nature of Pavel Dorf

In the spring of 2013, Powell received the citizenship of this small country by donating $250,000 to the St. Kitts and Nevis island fund in the Caribbean and investing in it. With a passport to this country, he can travel without a visa to 132 countries of the world, including the European Union and England.

Of course, Pavel’s new citizenship was revealed only in 2014; That is when he had officially left Russia, and this showed that Pavel had been thinking about leaving his homeland for a long time. Pavel Durov’s fortune

According to Forbes magazine, Pavel Durov’s financial situation has been growing since 2016. In the ranking of the 200 richest Russians in 2016, he ranked 135th with 600 million dollars, and by 2020, he was promoted to the 30th position with a fortune equal to 3.4 billion dollars.

Pavel Durov’s income from Telegram

Telegram income

Pavel made a fortune of 500 million dollars from the sale of his 12% stake in VK and is very interested in the field of cryptocurrency. He also managed to collect about 1.7 billion dollars from investors for the development of the Telegram-based blockchain known as TON; A project that, of course, failed; But Durov does not earn any income from Telegram.

Telegram is completely free, without ads and in-app payments, and Durov pays the cost of maintaining this platform completely from his own pocket. Of course, Durov has announced in a post that if he runs out of money to run Telegram, he will probably have to turn to public donations or in-app payments; But he will never enter the world of advertising.

Paul Durov’s moral qualities

Pavel is a supporter of the school of libertarianism in the political and economic fields. This view of his is clearly evident in his unwillingness to cooperate with government organizations. He believes that no person or structure has the right to violate private property or personal information of people.

Powell supports the standardization of the educational system; Because he believes that modern schools in the West are a relic of the industrial era and educate people with stereotyped and closed views. He predicts that education in the future will be interactive and decentralized.

Powell supports high taxes on industries that are active in the extraction of raw materials and the abolition of taxes in the field of information and customs. He also believes that taxpayers should choose what projects their taxes will be spent on.

Durov also believes that the cancellation of registration, passports, entry visas, and military service is necessary, and he considers these to be the cornerstones of the feudal system. In his opinion, movement restrictions cause brains to escape.

Pavel is not interested in doing interviews and prefers to be in contact with the audience directly through his posts on the Telegram channel and website.

When Pavel was 33 years old, he stated in a post that he had not consumed sugar, meat, or fast food for a long time, did not drink energy drinks, tea, and coffee, turned away from nicotine and alcohol and does not watch TV.

Who is the Telegram team made up of?

Telegram is run by Pavel Durov and his brother Nikolai. Pavel supports Telegram from the economic and ideological aspects and Nikolai from the technological aspect. To build Telegram, Nikolai created a unique custom data protocol called MTProto, which is open-source, secure, and optimized for use in multiple data centers. Details of the other people involved in the project are unknown, although Powell mentioned in a 2016 interview that his team consisted of 15 people.

Where is Telegram based?

Most of the Telegram developers were born in St. Petersburg, and after the tension with the Russian government, they left the country with Pavel and his brother and settled in Berlin, London, and Singapore for a while.

Telegram team members are currently in Dubai and are ready to change their place of residence again if the internet regulations of this country change.

Interesting facts about Pavel Durov

Powell dresses distinctively. In the photos, he always wears black clothes, and this is a kind of homage to his character Neo in the movie Matrix; For this reason, he is sometimes called Neo-Russian. In a book about Durov, Nikolai Kononov wrote that “he sees himself as the engineer of his own world”, and this description is somewhat consistent with the world of The Matrix.

Pavel learned to code while in school and used this skill to change the welcome screen image of the school computers to annoy a teacher he didn’t like. Pavel has a close relationship with his brother, who is also a skilled coder.

Pavel launched the VKontakte social network at the age of 22. The VKontakte office was located on the fifth and sixth floors of the iconic Singer House building in St. Petersburg.

In 2011, when Russian authorities asked Durov to remove some anti-government posts from VK, Durov responded by posting a photo of a dog wearing a hoodie and sticking out its tongue.

In 2012, Pavel and some VK employees made paper rockets worth more than a thousand dollars and threw them out the window. The value of each rocket was about 70 dollars. This movement later inspired the Telegram icon.

According to reports, Durov spends $1 million of his own money every month to run Telegram. To date, this platform has not generated a single dollar for Durov.

The number of monthly active Telegram users reached 100 million in 2016. Durov celebrated this success by throwing a big party in Barcelona.

Durov planned to raise 2 billion dollars from investors to run his company with the initial offering of a coin called “Gram” on the Telegram Open Network blockchain, But this project was stopped by the decision of the American court.

The popularity of Telegram is increasing every year. In 2021, the number of active Telegram users reached 500 million people per month. Telegram is most popular in Iran, Russia, Malaysia, Ukraine, India, Italy, Spain and Saudi Arabia.

Pavel Durov and Telegram

Founded in 2013, Telegram uses a secure end-to-end encryption method that makes it nearly impossible to decrypt messages. This feature, along with being free without a single ad or in-app purchases, has made Telegram take a significant share of the market from Facebook Messenger and other competitors; But this platform with 500 million active users per month is far behind WhatsApp with 2 billion users and Facebook Messenger with 1.3 billion users; But Durov says that the growth of Telegram is fast and most new users enter the world of Telegram through the suggestion of other users.

Our growth depends only on our users who recommend their friends to download and use Telegram. Every day, 350 thousand new users register in Telegram, without any effort on our part.

Durf attaches great importance to the principle of simplicity in the design of Telegram. In an interview with Wired in 2016, he said:

15 billion messages are sent daily through Telegram. Telegram’s main engineering team consists of 15 people, and obviously with this number, we had to automate many tasks and hand them over to scripts and artificial intelligence.

Telegram does not generate a single dollar of revenue for Durov, it has no permanent office and consists of a very small team. Before settling in Dubai, the Telegram team moved every two to four months. Dorf has announced that his team is ready to leave Dubai for a new destination if needed.

The company is so confident in the security of its proprietary protocol, called MTProto, developed by Nikolai, that it is offering a $200,000 reward to anyone who can hack it. It’s not an uncommon move to offer rewards to users who find bugs in products, But bounties of this magnitude are usually only reserved for critical bugs in widely used programs such as Windows.

According to Durov, no one has succeeded in hacking MTProto so far; But a Russian man who managed to find a serious problem in Telegram in 2014 was rewarded with $100,000.

Telegram is open source and allows any developer to create their own Telegram even for desktop computers. Today, most new messaging services, including WhatsApp, create applications for use in all situations and do not allow disparate developers to access their code. Of course, they can’t be blamed, because it’s difficult to maintain a centralized language and a single security model across several different applications. Meanwhile, monetizing a platform requires more planning than monetizing a simple paid app.

However, the VKontakte platform has gained a lot of success by allowing developers to build their own alternatives from it. More importantly, Telegram operates as a non-profit organization and does not intend to charge users for its services or sell their information to third parties or governments.

The company wrote on its FAQ page:

Telegram is not built for monetization and never accepts advertising or external investment. We are not looking to create a “user base”, but we are looking to create messaging for people.

In a post on Telegram, Durov announced that in 2021, to manage the costs of a platform with 500 million users, he will add a monetization section to Telegram. This section includes new paid features, paid stickers, and a platform called Ad Platform for commercial channel owners to generate income.

Telegram vs WhatsApp

The main difference between Telegram and WhatsApp is its highly encrypted structure, open API for access by developers and other users, and its strictly anti-commercial manifesto. In a world where Facebook simply buys its competitors (including WhatsApp for a whopping $22 billion), Durov’s refusal to sell Telegram is truly admirable; And of course, we should not forget its many, completely free and artistic stickers.

Users are becoming more aware of the importance of their privacy and looking for ways to protect their data. For this reason, Telegram has not sold a single byte of data from its users to any third party since its launch, which has significantly increased the popularity of this platform.

However strict privacy policies and strong data encryption are not enough to attract users who have depended on WhatsApp for years. In order to be able to compete with giants like WhatsApp and Facebook in the suffocating market of messengers, Telegram needs to be better in every way: faster message transmission speed, more beautiful design, more features, and attractive features in every update. It is only in this way that it is possible to provide better privacy and security than WhatsApp to users who may not be sufficiently concerned about security.

Telegram and terrorism

Telegram Pavel Dorf

Telegram’s strict policy on privacy and its non-cooperation with the authorities of countries to provide users’ information have made some people consider this platform dangerous and a place for terrorists and criminals to operate without supervision. In fact, in a new report published in June 2021, the German magazine Spiegel described Telegram as a dark empire, the most dangerous messenger, and the “equivalent of the dark web in the pocket” of users.

Critics of Telegram describe it as the dark web in users’ pockets

In 2016, Telegram blocked 78 public channels promoting ISIS ideology. Durov told Wired that the company is building tools to deal with malicious channels more effectively.

Is this enough? Probably not, as we are a small team and trying to hire more people to review reports and requests. We are gradually building a tool to automate this process. All this takes time, but we try to consider it one of our priorities. 

In response to criticism of Telegram’s 100% protection of user data, Durov said in one of his interviews during the Mobile World Congress:

The political solutions proposed against cryptography are not supposed to be effective against terrorism. If you block a site like Telegram, terrorists won’t even notice.

Golden sentences from Pavel Durov

Paul Dorf's sentences

– Don’t give up until you have a really exciting idea. If you’re on the fence about a decision, go get some sleep and see how you feel about it when you wake up.

– In order to accomplish something, you must have enthusiasm, curiosity, and the ability to facilitate the process. The meaning of making it easier is to remove all the additions and focus completely on the essence of the matter.

– Success means being excited about what you are doing and focusing on it.

– If your mind is busy with several projects and you can’t concentrate well, go read books unrelated to business and technology. Give your mind a break and let it think about different topics in comfort for a while.

– People value social status too much. What difference does it make if you live in London or the countryside? As long as you have internet, there is no difference between the two. Life in the village is healthier and cheaper, But people prefer to live in expensive cities and pay a lot of money for rent. The only reason they are in that city is to have a job so they can pay rent and buy expensive appliances. This is a vicious circle.

– If you want your life to be simpler, you need to get rid of other people’s voices in your head. We are too influenced by people around us; Our relatives and friends and what they think about what constitutes success or what is good or bad. We must completely get rid of these influences. We should be able to be indifferent to what others think or say about our work. After this step, we should focus only on what we need.

Where there is no competition, there is no progress

– Spend more time in solitude and silence and be happy about it. People get addicted to being in groups. For example, in America, when two people sit together in silence, they feel awkward. Sometimes you need to have a space that is not influenced by anyone.

– The most important personality traits for a founder are love and passion for building, curiosity, self-discipline, passion, and persistence.

– What people don’t know about Renaissance men is that these people didn’t pursue several different professions at the same time. Maybe some of them were like this, But most of them would choose one area and concentrate on building it completely and then move on to the next project. We humans can do many things, but not simultaneously.

– When something happens that I can’t change, I prefer to think about the good sides of it because every event, even the most tragic ones, has good and bad sides. You just have to see them and focus on them. It’s useless to be upset about something you can’t change. You have to adapt to the situation and think about what can be done with what you have.

– Learn foreign languages ​​to deepen your understanding of the world and to open unprecedented opportunities for learning progress, and career growth.

– The value of money is overrated, because making and creating is more attractive than consuming, and the inner state is incomparably more important than the outer world.

– Where there is no competition, there is no progress.

– The value of communication and conversation has been greatly exaggerated. An hour alone is more useful than a week of talking.

Emphasizing secure communication and libertarian ideas, Pavel Durov is a person with independent thinking who has covered these ideas comprehensively in the development of the Telegram project. What do you think about this character and his moral qualities? Is the Dwarf Telegram a dark and dangerous empire or a glimmer of light in the insecure world of the Internet?

Is Telegram really safe?




Is Telegram really safe?
Telegram claims to have very high security, but it is not in the list of the most secure messengers in the world; What is the matter?

Is Telegram really safe?

Telegram is not very popular in America and Canada for some reason (140 million monthly users of Facebook Messenger against only 10 million users of Telegram!), But it is extremely popular all over the world and its number of monthly users reached 800 million in 2023. This service, which was filtered in Iran a few years ago, still has a large number of users and by adding new features in each update, it increases the number of users day by day.

Telegram, with its diverse capabilities, fast performance, and special benefits such as free cloud space, is definitely considered one of the best, and for this reason, it has many fans in Iran; But when it comes to user security and privacy, everyone has a different answer. If you ask the founder of Telegram, he says that this messenger has great security, but this platform is not on the list of the most secure messengers in the world. In the following article, we have tried to find a convincing answer to this controversial question as much as possible.

Telegram is born

The date of birth of the Telegram messenger application goes back to August 23, 1392, which was first released for the iOS operating system. At that time, Telegram did not have many features, but due to its cloud infrastructure and the permanent storage of chats and content sent in the company’s cloud servers, it was still one ahead of its fierce competitors, Viber and WhatsApp.

Nikolay and Pavel Durov, founders and developers of Telegram, released the Android version of this messenger after two months. Since the Durov brothers were from Russia and owned a large part of the shares of the social network VK, there were many concerns about the security of information on this messenger and the possibility of the Russian government controlling and monitoring users.

The social network VK was also developed by the Durov brothers, but according to them, the company is now owned by the Russian government. Pavel Durov, CEO of Telegram, left Russia in 2014 due to pressure to provide user information to the government and sold all his shares in VK.

Although the business name “Telegram” is registered as a limited liability company in Dubai, there is not much information about the offices, infrastructure, and possible sponsors of this messenger. According to the claims of former employees of VK, a number of Telegram developers live in Russia and in the city of St. Petersburg, but Pavel Durov called this claim unfounded and said that in order to avoid pressure from governments and protect the security of users, the Telegram team moves from one country to another every year. places

According to Pavel Durov, after leaving Russia in 2014, he decided to establish the main office of the Telegram messenger in Berlin, but due to the pressure of the German government to access user information, Telegram had to leave this country and transfer the servers to another country. It became another

Since 2017, Telegram has chosen Dubai as its headquarters. In the FAQ section of Telegram, it is written that they are satisfied with life in Dubai; But as soon as the internet laws of this country change, they are ready to change their location.

Is Telegram safe and does it protect our data?

If we want to answer briefly, Telegram is safe in most cases; This means that all exchanged messages are partially encrypted, but end-to-end encryption, which makes it impossible for even the service provider to access the messages, is only available in calls and Secret Chat; While messengers such as WhatsApp and Signal support end-to-end encryption by default in normal chats

Of course, another advantage of Secret Chat in Telegram is that you can automatically delete sent messages, images, audio messages, and videos after they have been viewed by the recipient of the message.

These days, end-to-end encryption is the first word in the security of messengers; Because when you use end-to-end encryption or E2EE to send an email or message to someone, no hacker, neither government nor even corporate, can access the text of your message. In this type of encryption, messages are mixed in such a way that only the intended sender or receiver can decode the message, and therefore, it is considered the highest level of security.

There is no end-to-end encryption in normal Telegram messages

However many users do not know that in normal messages and content sent in Telegram groups and channels, there is no end-to-end encryption and the ability to automatically clear posts, and to increase the security of messages, it is necessary to use secret chat. As a result, when you send a message normally on Telegram, the content of the message is stored and accessible on Telegram servers. Telegram’s main reason for this decision is that most of the groups and channels are public and use them to send messages to a large number of users.

On the other hand, malicious users and profit-seeking people can use the great potential of Telegram groups and channels to commit fraud and publish immoral, misleading, and violent content.

In the past years, some Telegram groups and channels caused big problems by publishing inappropriate content. Of course, like other social networks, Telegram has its own rules and policies, and in this regard, it has developed algorithms to deal with content that violates its rules; However, it seems that he was able to use these algorithms 100% effectively. Finally, users themselves must report inappropriate content.

For more protection against this type of content, you can activate options such as Restricted Mode, which automatically detects and filters inappropriate images, by referring to Telegram’s security and privacy settings from Settings > Privacy and Security.

Another feature that is recommended to disable is People Nearby, which makes it possible to communicate with users near you. This feature can become a dangerous tool in the hands of hackers to access your exact geographical location. To disable People Nearby, go to Contacts > Find People Nearby and click on the Stop Showing Me option; This will change the option to “Make Myself Visible”.

Only the Telegram application is open source; Messages are encrypted with a proprietary protocol

For even more security, you can completely cut off Telegram’s access to your location; To do this on iOS, go to Settings > Privacy and Security > Location Services > Telegram and select Never from the Allow Location Access tab. On Android phones, go to Settings > Apps > Telegram and turn off the Location option from the Permissions section.

Another important thing you should know about Telegram security is that its openness is only related to the client application, and this messenger uses a special protocol called MTProto to encrypt user messages on the server side. Security researchers believe that to increase the security of the system, the use of standard encryption protocols is preferable to proprietary protocols. The reason for this is the possibility of identifying the vulnerability of protocols and fixing them quickly.

Does Telegram collect user data?

Like other messengers, Telegram stores some user data on its servers for 12 months; Including username, username change history, details of the device on which the messenger is installed, application usage habits, and users’ IP address. Of course, none of this data is used for advertising or commercial purposes, but there is always a possibility that under the pressure of governments, Telegram will have to provide this information.

How do we increase the security of our Telegram?

To increase the security of Telegram, we recommend the following steps:

Enabling Two-Step Verification

To activate this feature, go to Settings – Privacy and Security. Note that by enabling two-step verification, the possibility of hacker interception and access to your user account is almost zero.

Limit the information you share with others

Hide your mobile number, bio text, and profile picture from others. Also, in chatting with people you don’t know, strictly avoid providing information such as your real name, location, and any other information that will lead to finding your other accounts on the Internet.

Use secret chat as much as possible

Sometimes friends and family members may be in the same group, but to ensure the maximum security of chats, use secret chat with end-to-end encryption support instead of regular chat.

Join groups and channels with caution

If you don’t know a group or channel, never join it. Remember that the channel admin and other group members can access your account and save information such as your name and profile picture. Also, avoid emotional attachment to people you don’t know.

Avoid sending money or your bank card information to strangers

Today, fraudsters may pretend to be a support specialist, bank employee, or anyone else you think is trustworthy in order to access your bank account. In order to avoid fraud in Telegram, remember that you never need to pay money or share bank account information through Telegram to do anything. After all, in many cases, by checking the user ID or the person’s number and asking the relevant organizations, it is possible to verify the fraudsters’ claim.

Avoid clicking on suspicious links

If a stranger poses as a support expert or office worker and forces you to click on anonymous links, never accept their request. Due to the fact that most phishing attacks, infecting the victim’s system with malware, stealing information, and internet sabotage are done using malicious and anonymous links, avoid clicking on these types of links.

If something is too dreamy, doubt it

We all know that the probability of winning the lottery, finding amazing discounts, or encountering rare opportunities in life is very low, and if someone makes such claims on the Telegram platform, we should doubt his claim and identity. The best way to deal with such situations is not to respond to strangers.

Samsung Galaxy A55 vs Galaxy S23 FE




Samsung Galaxy A55 vs Galaxy S23 FE

It’s an unlikely thing to compare the Samsung Galaxy A55 to the Galaxy S23 FE in an article, but Samsung’s pricing strategy made us compare the two phones. After launching this year’s popular Galaxy A55 at around €450 (now just over €400), the company has positioned it very close to its budget flagship, the Galaxy S23 FE.

But these two phones are by no means created equal. The Galaxy S23 FE is still more expensive than the Galaxy A55 (it now retails for around €500), but it also offers a flagship-like experience, while the A55 tries to strike a good balance between hardware and cost. They have two different target audiences and very similar price tags.

  • Designing
  • screen
  • battery life
  • charge
  • Speaker test
  • Function
  • cameras
  • Summary

Before we compare, head over to our specs page and compare the Galaxy A55 vs S23 FE to see what we’re expecting in this comparison.

Size comparison

Comparison of Galaxy A55 and S23 FE

The Galaxy A55 and S23 FE are similar in size, but there are some notable differences. The S23 FE is the more compact choice, with a slightly smaller screen (0.2-inch difference) resulting in a shorter and slightly slimmer body.

The difference in absolute size may not seem like much on paper, but you can feel the difference by holding the two side by side.

The Galaxy S23 FE feels more comfortable in the hand due to its rounded side bezel. It feels better in the hand, as the Galaxy A55’s sharp edges sink into your palm. On the other hand, others will like the A55’s visual design more.

Build quality is pretty much the same – Gorilla Glass sheets on the front and back are held by aluminum side frames. Notably, the A55 leads the way with a newer Victus+ Gorilla Glass sheet on the front, while the S23 FE settles for Gorilla Glass 5. Instead, given the S23 FE’s higher IP68 ingress protection compared to it, you might have a bit more peace of mind. to IP67 A55, which means that its water resistance is slightly higher.

Compare the show

Comparison of Galaxy A55 and S23 FE

Apart from the screen size, the Galaxy A55 and S23 FE have identical displays. If you’re looking for a slightly larger panel, the 6.6-inch OLED A55 will probably suit you, while the 6.4-inch OLED S23 FE will appeal to users looking for a more compact solution.

Both screens support HDR10+. They tick at 120Hz, the resolution is 1080p+, and we measured maximum brightness in manual and auto mode. The latter is equally bright with both – around  1000 nits.

Battery Life

The difference in battery life between the two devices is night and day, and the smaller cell inside the Galaxy S23 FE is partly to blame.

The A55 has a standard 5,000 mAh unit, while the S23 FE settles for a 4,500 mAh battery. But the difference in endurance is so great that we can’t blame total capacity alone.

Note that we’re comparing the A55 to the Exynos version of the Galaxy S23 FE because the A55 isn’t available in the US yet, where you’ll usually find the Snapdragon S23 FE, which objectively has better battery life in all tests.

The Galaxy A55 beats the Exynos S23 FE in battery endurance tests. The average active use rating is 13:27 hours versus the S23 FE’s 8:28 hour active use rating.

Comparison of Galaxy A55 and S23 FE

Despite the larger screen, the A55 scored better in all four tests. The video playback time was twice as long. The Exynos 1480 is much more battery-friendly than the flagship Exynos 2200.

Charging Speed

The charging speed is not suitable for any of these two phones. Samsung has rated the charging capability of the A55 and S23 FE at 25 watts compared to the Power Delivery standard. Neither comes with a charger in the retail box either.

As expected, the difference in charge time is negligible despite the S23 FE’s smaller cell. The two seem equally slow at 15 and 30 minutes, but the A55 beats the S23 FE by a few minutes at the end of the charge cycle. However, the difference will remain negligible in the real world.

Comparison of Galaxy A55 and S23 FE

It is important to note the S23 FE’s wireless charging capabilities, which the A55 lacks. The former also supports 15W wireless charging and reverse wireless charging, which can be useful for your wearable accessories that support wireless charging.

Speaker Test

The two phones share a similar hybrid stereo speaker setup, meaning one of the speakers doubles as a phone. But the tuning seems to be very different as well as the volume.

The Galaxy S23 FE is undoubtedly louder, reaching a loudness score of  -23.7 LUFS, with the A55   trailing at -25.7 LUFS, but still rated as ‘Very Good’.

Comparison of Galaxy A55 and S23 FE
However, upon closer inspection, the Galaxy A55 might be a better choice when it comes to sound quality. The Galaxy S23 FE’s bass is a bit deeper, but it’s barely noticeable. The A55 sounds cleaner overall, with more pronounced vocals and less distortion at high volume levels.


To no one’s surprise, the Galaxy S23 FE outperforms the Galaxy A55 by a large margin. After all, the Exynos 2200 in the S23 FE is a flagship chipset, and the Exynos 1480 is a mid-range chip, even though it was recently released.

Comparison of Galaxy A55 and S23 FE

The memory configuration is the same, with both devices offering 8GB/128GB by default, capping the internal storage capacity at 256GB. The S23 FE only gives you up to 8GB of RAM, while the A55 can expand up to 12 GB. The second one also has a microSD card slot.

Benchmark Performance

We already know that the S23 FE (Exynos 2200) is more powerful, but by how much? Well, in pure CPU benchmarks, the Exynos 2200 outperforms the Exynos 1480 by around 18%, and the gap widens in single-core tasks – up to 41%.

Samsung Galaxy A55 vs Galaxy S23 FE


In mixed workloads, such as the AnTuTu 10 test, the difference is hard to ignore. The Exynos 2200 is about 56% faster than the Exynos 1480, and the Xclipse 920 GPU is probably the main reason for that.

An even bigger gap can be seen in GPU-based tests like 3DMark Wild Life, where the Galaxy A55’s Xclipse 530 GPU is more than twice as slow as the S23 FE’s Xclipse 920.

Camera Comparison

Interestingly, these two devices have very similar camera systems. They offer 50MP primary cameras using a 1/1.56-inch sensor size, f/1.8 aperture, and 1.0μm pixels. Both are also optically stabilized. The only difference is in the vendors.

The ultra-wide cameras are pretty much the same too – 12MP with f/2.2 aperture and a 123-degree field of view. Although the S23 FE has a slightly larger sensor behind the optics.

The Galaxy S23 FE is a more versatile solution as it has an 8MP telephoto camera with 3x zoom. That alone might sway buyers who are on the fence about the better photography solution of the two.

Image Quality

In terms of actual image quality, these two devices take very similar photos with their primary cameras. We can hardly find any meaningful difference between the two. However, the S23 FE’s ultra-wide resolution produces slightly better images – they’re cleaner and have a wider dynamic range.

The 3x telephoto camera beats the A55’s 2x zoom crop any day of the week. This is a very clear cut.

Galaxy A55: 0.6x Galaxy A55: 1x Galaxy A55: 2x
Galaxy A55: 0.6x • 1x • 2x
Galaxy S23 FE: 0.6x Galaxy S23 FE: 1x Galaxy S23 FE: 3x
Galaxy S23 FE: 0.6x • 1x • 3x

The S23 FE excels at night with better image processing and quality. It may be because the ISP chipset is more capable. Overall, images are cleaner and offer a wider dynamic range.


Looking at the specs sheet, the Galaxy S23 FE is more affordable despite the higher price tag. Under the hood, it has superior hardware and is also a more capable photographer. And if you’re looking for a more compact and convenient solution, the Galaxy S23 FE will certainly fit your palm better.

A deeper look reveals that the Galaxy A55 can get you a good chunk of the same distance for a slightly lower price. The A55 surprises with far superior battery life, identical display quality and specs, comparable performance of the main camera in various scenarios, and possibly a better stereo speaker setup.

So, unless raw camera performance and versatility aren’t your top priority, the Galaxy A55 is the more sensible choice of the two.
