Many airlines ask passengers to put their phones in flight mode during the flight to avoid accidents; But how true is this belief?
Does not activating the flight mode cause the plane to crash?
It has probably happened that when boarding the plane and before the flight, the flight attendant will ask you to turn off all your electronic devices or put your mobile phones on flight mode. Airplane mode prevents the device from receiving and sending radio waves by disabling all wireless device connections, such as cellular network, Wi-Fi, Bluetooth, and GPS. At first glance, it may seem logical to put the phone in flight mode, but how true is the belief that using the phone while flying will be disastrous?
In 2022, Europe will allow passengers to make phone calls and use the Internet to do their work during the flight. But to do this, all planes had to install a device called “Pico-cells”. Picocell is a device similar to a traffic controller that prevents cell phone signals from interfering with aircraft communication systems.
By installing Picocell in the plane, you can easily connect to the Internet
You might think to yourself that picocell is a very new technology, but it is interesting to know that 20 years have passed since the creation of these devices. Before we delve into the myth of airplane flight mode, let’s learn a little more about picocells.
What is Picocell?
Before getting acquainted with the concept of picocell, it is necessary to get acquainted with the definition of tuberculosis. The area covered by telecommunication waves, towers, or base stations in mobile phone networks is called a cell. Base stations are the very tall towers you see along roads or highways. To better understand this concept, divide the whole city into small pieces like a beehive. Each segment is a tube covered by one of the Base Transceiver Stations (BTS). By placing all cells next to each other, the entire city can be covered by telecommunication waves.
base station
Note that there are different types of cells and their type depends on the coverage of telecommunication waves. “Femto-cell” refers to the smallest cell and “Macro-cell” refers to the largest cell. Therefore, the range of cells varies from a few meters to tens of kilometers. Some mobile phone operators sell Femtocell directly to their users in order to improve home network coverage. Using the Femtocell is very simple, just plug it into the power outlet, then connect the Ethernet cable from the Femtocell to your router or modem.
The mobile network generally consists of two parts:
Radio network: This section consists of all the equipment and infrastructure that is required to send and receive radio signals between mobile devices and base stations. BTSs act as the interface between the mobile network and user devices.
Core network: This section includes all the equipment and infrastructure used to manage and route calls, messages, and data in the mobile network.
Note that the mobile network is also composed of other parts, but for simplicity, we will focus only on the two radio networks and the core. Femtocells, microcells, macrocells, and picocells are part of the radio network. These cells connect your mobile phone to the radio network by creating a suitable network coverage. Next, the radio network will be connected to the mobile core network. The connection between the base station and the network core is called Backhaul.
Mobile network operators use cell towers or base stations to create mobile network coverage. As we said, the coverage area where the base station signals can successfully reach the mobile phone is called TB. Mobile phone operators have deployed a large number of base stations for nationwide network coverage.
Each base station consists of a certain number of cells. The cells in the mobile network have different sizes. The size of each tube depends on the area to be covered. Cells are represented using hexagons connected to each other (image below). A group of interconnected cells is called a cluster.
Hexagonal cells next to each other
Cells are connected to each other. Therefore, you can easily go from one point to another without disconnecting your mobile phone. Microcells are primary cells that provide primary coverage within the mobile network.
As we mentioned at the beginning of this section, tuberculosis has different sizes. Different types of cells in the mobile network are shown in the image below. The smallest cell is called femtocell and the largest cell is called microcell. Femtocells cover up to 10 meters and macrocells up to tens of kilometers. Picocells are larger than femtocells and macrocells are larger than picocells.
The use of different types of tubes in different places
An important question that may arise is why we need cells of small and large sizes. When using a mobile phone and communicating, the quality of the communication and the coverage of the telecommunication network are of great importance. Adequate coverage means that signals can successfully travel from the base station to the mobile device and vice versa. The use of cells with different sizes in the mobile network has several advantages. These benefits include increased capacity, coverage, signal quality, and traffic management.
Smaller cells are cheaper than larger cells because they require less equipment and infrastructure. Four cells are compared in the table below.

Comparison table of types of tuberculosis
The femtocell is the smallest tube. In most cases, mobile operators sell these cells to their customers as signal boosters. These cells can cover an area up to 10 meters radius.
Different cells together allow access to the Internet, even in the most remote places
Picocells are larger than femtocells. These cells can provide coverage and capacity up to a radius of 200 meters. Smaller cells provide more capacity for users in densely populated areas and reduce interference between users. Also, they use radio frequencies more efficiently.
Mobile phone operators are responsible for managing and setting up picocells. Therefore, these cells must be professionally installed and connected to the main power and “backhaul” like any normal base station. Picocells are commonly used in buildings and stores, and from 2022 onward in airplanes.
Small cells cover small areas and are typically used to provide adequate coverage in areas where macrocell signals cannot successfully reach, such as inside buildings or tunnels. Picocells use different radio frequencies than macrocells. This allows them to deliver stronger signals in smaller areas without interfering with macrocells.
The most important advantages of using picocells are:
Better coverage: Picocells provide a stronger signal compared to macrocells.
More capacity: Picocells support more users in a certain area. This issue is of great importance in high-traffic places, such as shopping centers and stadiums.
Better quality of service: Picocells offers better quality of service, such as better voice clarity and higher data rates.
Lower cost: Picocells are more economical than macrocells due to their smaller size and lower power consumption.
Although the use of picocell has many advantages, its disadvantages such as covering small areas, interference (loss of quality), and complexity cannot be ignored.
Microcells are larger than picocells and cover a radius of up to two kilometers. Macrocells are the basic cells that mobile operators use to provide basic network coverage.
Now that we are familiar with the types of cells and the use of picocells, let’s discuss the issue of activating the flight mode of mobile phones in airplanes and the history of this misconception.
Where did the story of activating the airplane mode start?
Nowadays, mobile phones have become an integral part of our lives and it is not strange that we want to still have access to the ability to make calls and use the Internet in any situation, including during a plane flight.
The American Civil Aviation Organization first suggested activating flight mode in airplanes in 1963
The US Federal Aviation Administration (FAA) has concluded that portable electronic devices such as cell phones can interfere with aircraft radios and other electronic systems. This led to concerns regarding the use of these devices while flying.
The FAA first published rules in 1963 to address this concern. According to these rules, airlines are the best option for choosing the allowed electronic devices on board. In 1991, the Federal Communications Commission (FCC) banned the use of cell phones and other wireless devices on airplanes. The ban included wireless devices using the 800 MHz frequency. The 800 MHz frequency is used for a wide range of terrestrial telecommunications services, including mobile services.
The ban was imposed due to possible interference with wireless networks on Earth. The FAA recommends that airlines turn off portable electronic devices capable of transmitting signals, including cell phones, during flight to comply with FCC rules and to minimize risk to aircraft radios and other electrical and electronic systems.
At first glance, the establishment of these rules may seem logical. But in 2005, a member of the Communications Commission emphasized that due to the use of picocells, there would be no problem with using mobile phones while flying. Nicholas Sabatini, the then CEO of the FAA, believed that due to technological advances, there may no longer be a need to ban cell phone use on airplanes.
However, the ban on the use of mobile phones remained as the law. In 2013, Tom Wheeler, the new CEO of the FCC, tried to make a big change by lifting the ban on making calls and using the Internet while flying. But this issue caused a big controversy.
What do the opponents and supporters of activating the airplane mode say?
For some people, using a cell phone while flying is like a “cage fight” at 35,000 feet. These people say that as much as cage fighting is dangerous for the contestants, the use of cell phones while flying can also endanger the lives of passengers. Also, this group believes that making calls during the flight will cause inconvenience to the passengers and cause discomfort and stress to them because the space of the plane is small.
Using mobile phones while flying may cause stress and anger in passengers
On the other hand, the other group believes that due to the advancement of technology and since there is no possibility of interference of mobile waves with aircraft navigation equipment, there is no need to ban the use of mobile phones in airplanes. According to them, governments should not interfere in the way airlines manage and serve passengers, and airlines should be able to decide for themselves. They also say that when we have coped with the crying of babies, the incessant conversation of passengers, and their commuting, why should the conversation be on our line phone?
Why has airplane mode activation become a popular belief?
This, like many other beliefs, is mostly accepted due to habit and popular belief. Many travelers believe that turning on airplane mode, like doing many other things while flying, not only keeps them safe but also prevents passengers from getting angry during the flight. However, there is no evidence of a relationship between passenger anger and in-flight cell phone use.
Some say that talking on the phone on the plane annoys the passengers
Today, passengers on most flights can connect to Wi-Fi, make voice calls, and surf the Internet by paying a small fee. If more aircraft use picocells, it’s likely that these things can be done for free. While Wi-Fi calling is available on some airlines, SIM card calling is still prohibited on many flights.
The truth is that cell phones haven’t caused any disruption to aircraft electrical systems or ground wireless services for years, and it was even possible to make in-flight calls with Airfone phones until 2013. It seems that the main reason for the flight mode legend to remain is the airline’s policy, the annoyance of passengers from the sound of other passengers’ conversations, and the torment of people’s own consciences.
Finally, putting the mobile phone in flight mode is still one of the important debates for which the definitive result has not been determined. Currently, many airlines require passengers to put their phones in flight mode; But European lawmakers are trying to lift the ban on making calls on airplanes. Probably the day when all airlines end this ban, the name of the “flight mode” option in smartphones will be changed; Or maybe it will stay that way, and years from now people will be asking themselves why disabling all phone connections is called Airplane Mode.
Leaving the Earth’s atmosphere is not just the experience of floating in the environment. There are also other amazing and troublesome events that can only be experienced in space. In this article, we will talk about the strangest things that can happen to humans in space.
The strangest things that can happen to humans in space
When it comes to space and astronautics, we all remember very interesting movies in which strange things happen to astronauts. Movies with exciting stories, most of which are nothing but the authors’ imaginations; But there are other very amazing stories happening in space that are completely real and have nothing to do with human imagination. In this article, we try to discuss some examples of these events and introduce you to the wonders of space travel.
Strange things that happen to humans in space
The human heart changes shape in space
It may seem a bit strange and even unbelievable that traveling to space can change the shape of the heart, But such a thing happens in reality and scientific studies have proven it. Less work of the heart and less pumping of blood leads to a decrease in the volume of the muscles of this organ, and this ultimately causes the hearts of astronauts to become more spherical by about 9.4%.
Despite the temporary nature of these conditions, some doctors believe that the reduction in the volume of the human heart during space travel may have serious consequences. According to NASA, researchers are researching this issue, and the results of this study will not only help astronauts but will also affect ordinary people and the inhabitants of the planet.
There is a possibility of mental problems in space
Living in the extraterrestrial atmosphere is associated with many problems. Changing living conditions and experiencing a completely different environment with very specific conditions imposes many psychological pressures on astronauts. These issues cause astronauts to experience special psychological conditions and are susceptible to various problems such as anxiety and depression.
Being away from family, lack of simple facilities such as sunlight or even fresh food, and heavy work are among the reasons that expose astronauts to various mental illnesses.
Human vision decreases in space
Visual impairment caused by intracranial pressure or VIIP is another space travel wonder faced by astronauts. This problem was observed for the first time in 2005 and in an astronaut named John Phillips. The Washington Post investigates this issue in an article and states that Phillips experienced a significant loss of vision after returning from his space trip. This incident prepared the groundwork for the researchers’ research for further investigations.
Additional research showed the changes in the appearance of the astronauts’ eyes and the loss of their vision after returning from space travel. Currently, the only possible reason that has been proposed for the occurrence of such conditions is the lack of gravity and the creating double pressure on the astronauts’ skulls; Of course, the research in this field continues and it is still not possible to say with certainty a specific reason for the occurrence of these conditions.
Traveling to space, along with its excitement and surprises, also brings many problems for humans. One of these problems is the weakening of the body’s immune system in space, which was first discovered by astronauts during the Apollo mission. The story was that the astronauts in this mission experienced problems such as irregular heartbeat, dehydration, and inner ear disorder, and faced many problems after returning from the mission.
Studies conducted in this field have shown that after leaving the Earth’s atmosphere, the immune system of astronauts weakens, in part due to the abnormal activation of a type of immune cells called T-regulatory lymphocytes. This weakening is sometimes so severe that it causes astronauts to deal with latent viruses such as chicken pox in addition to simple infectious diseases such as colds after returning from space travel.
Astronauts can lose their fingernails
As you know, astronauts wear special clothes to carry out their missions in space, which includes astronaut gloves. These gloves are designed in such a way that they put a lot of pressure on the astronauts’ hands and nails; This will eventually lead to their nails falling off.
It is true that the fall of fingernails or their swelling is not a simple matter that can be easily passed over, But it seems that doing more research to design more suitable gloves can minimize the possibility of this problem and astronauts will not face such a problem in the future.
Human height grows taller in space
Another wonder of space travel, which makes it one of the favorite trips of ordinary people, is the increase in height that occurs during this trip. As soon as you leave the Earth’s atmosphere, the gravity is close to zero, and this causes the pressure on the spine to decrease significantly. The reduction of this pressure, in turn, causes the height of the astronauts to grow a few centimeters.
One of the studies that confirms the truth of this issue is the research that NASA scientists conducted on two twin brothers. In this study, one of the twins had a 342-day trip to space and the other brother was examined on Earth. The results of this and other research determined that the height of astronauts increases by 2 to 5 cm on average after space travel.
Mark Kelly (left) and Scott Kelly (right) made it possible for researchers to study the health effects of long-duration space travel by studying NASA twins.
Traveling to space leads to weakening of muscles
Another strange thing that happens to astronauts in space and affects their health is the weakening of muscles or atrophy. Long space travel causes muscle wasting in astronauts, so they are trained to exercise continuously during their journey.
NASA is working on this issue to find solutions to prevent the problem of muscle wasting. The reason for the importance of this issue is the need for astronauts to have strong muscles and a healthy body so that they can perform their difficult missions in space in the best possible way.
Space swells astronauts’ faces
A large volume of our body is made up of liquid. On Earth, gravity pulls this fluid down and collects some of it in the lower limbs; But in space, where microgravity prevails, our body fluids are more evenly distributed; As a result, astronauts’ faces look puffier than normal, and on the other hand, their legs appear thinner than when they are on Earth.
According to the Washington Post, “the phenomenon of puffy-faced bird’s legs” appears when blood and other body fluids accumulate on the side of the upper body due to low gravity and stay there; As a result, the heads swell and the legs shrink. In this situation, the appearance of the astronauts can change by swelling their faces. Astronauts may experience excessive blood pooling; As if their head is constantly cold. However, after a few weeks in space, your body will adjust to the change in gravity and some of the facial puff will fall asleep.
Space travel may increase the risk of cancer
Astronauts who spend 6 months in space are exposed to almost as much radiation as a thousand chest X-rays. Exposure to different types of radiation exposes the body to the risk of cancer, damage to the central nervous system, bone loss, and some cardiovascular diseases. However, it has been difficult to accurately calculate the level of risk so far. Also, scientists’ information about the impact of radiation in long-duration space missions to deep space destinations such as the Moon and Mars is still limited.
The more time a person spends in space, the more radiation they are exposed to and, theoretically, the more DNA damage they accumulate. It is not possible to say with certainty whether this DNA damage actually increases the risk of cancer; Because cancer is affected by many environmental and genetic factors. For example, it’s probably fair to say that today’s astronauts are probably some of the fittest people on the planet. They probably eat a healthy diet, exercise a lot, and don’t smoke or drink much alcohol. All these things reduce the possibility of getting cancer.
Strange events for astronauts during space travel have always been one of the most fascinating topics for ordinary people. The wonders of space travel are not limited to the things we have mentioned, and at the same time as science advances and the scope of research increases, we will definitely see more interesting news in this field in the near future.
Reviews of Motorola Edge 50 Ultra phone, price, technical specifications, design, screen, software, hardware, battery life and charging, and other specifications of this phone.
Motorola Edge 50 Ultra review
The Motorola Edge 50 continues to grow today with new additions to the lineup. After launching the Edge 50 Pro earlier this month, the OEM is now introducing the Edge 50 Ultra and Edge 50 Fusion. As expected, the Ultra is at the top of the range, while the Fusion is the most affordable of the three.
We will take a closer look at the Edge 50 Ultra and its flagship features. After all, this is Motorola’s top-of-the-line smartphone for 2024, and it offers a ton of premium features, including AI capabilities and a Pantone-calibrated display and cameras for more accurate and vivid color reproduction.
Motorola Edge 50 Ultra specifications at a glance:
Body: 161.1 x 72.4 x 8.6mm, 197g; Victus gorilla glass front, acetate back (wood based) or silicon polymer back (vegan leather), aluminum frame; IP68 dust/water resistant (up to 1.5m for 30 minutes).
Display: 6.70 inch OLED, 1B color, 144Hz, HDR10+, resolution 1220x2712px, aspect ratio 20.01:9, 444ppi.
Connectivity: 5G; two SIM cards; Wi-Fi 7; BT 5.4; NFC, UWB, USB-C 3.1 Gen 2 with DP 1.4 support.
Other specifications: fingerprint reader (under the display, optical); stereo speakers; Ready to support 6.
AI functions are possible thanks to the new Qualcomm Snapdragon 8s Gen 3 chipset, which sits between last year’s Snapdragon 8 Gen 2 and this year’s Snapdragon 8 Gen 3. while maintaining a relatively low price. Motorola seems to be looking for a more affordable flagship segment.
But despite the small agreement in the chipset department, Motorola does not make cameras, displays and chargers. The 6.7-inch OLED panel packs all the punch, runs at up to 144Hz and can charge up to 125W (wireless is 50W). The camera hardware looks good on paper. We’ve got a 50MP main sensor assisted by a 50MP ultra-wide unit and a 64MP 3x telephoto camera with a reliable f/2.4 aperture. Even the selfie unit is 50MP with autofocus, which is rare even in the ultra-premium segment.
Designing
The overall design language of the Edge 50 Ultra follows the Edge 50 family, and since the screen is the same as the Edge 50 Pro, the two phones feel the same in the hand. The Ultra comes in two variants – with a vegetable leather or wooden back. The latter is a bold approach, but will likely appeal to some.
Available colors include Forest Gray and Peach Fuzz (both vegetable leather options) and Nordic Wood (pictured below).
Of course, the wooden back is not pure wood. Motorola has used a special coating for the surface that preserves the wood-like texture while protecting it from water and oil, so it doesn’t change color or lose its appearance. Either way, the imitation is pretty good – almost like real wood.
The Edge 50 Ultra and the Edge 50 Pro look so similar that it would be hard to tell them apart if they both had plant-based leather. Camera hardware ditches the Edge 50 Ultra, as the telephoto uses a periscope lens and the round LED flash is replaced by a smaller, vertical flash.
Motorola Edge 50 Ultra vs Edge 50 Pro
The front and back panels are still rounded, which helps with grip, and to be honest, the wooden back is easier to hold. It also brings back a distant memory of Motorola’s Moto X in 2013 with its bamboo and wooden back.
The side frame is still aluminum, while the front glass is Gorilla Glass Victus. And for a 6.7-inch device with this many cameras, the weight gain at 197 grams is pretty impressive. Leather and wood are lighter than glass, so that could be an explanation.
As expected from a high-end smartphone like the Edge 50 Ultra, the device has IP68 ingress protection.
Hardware
The Edge 50 Ultra and Pro have very similar hardware for the most part, but as we mentioned earlier, the Edge 50 Ultra has a more powerful Snapdragon 8s Gen 3 chip that delivers flagship-level performance and features. One notable limitation is the chipset’s inability to record 8K videos. 4K is capped.
Motorola Edge 50 Ultra vs Edge 50 Pro
The curved OLED panel is a small step above the competition in terms of refresh rate, as the Edge 50 Ultra’s 6.7-inch display supports a 144Hz refresh rate. It remains to be seen whether Motorola has been able to make the best use of the display’s capabilities.
In addition to the 144Hz refresh rate, the panel also has support for HDR10+, 10-bit color depth, and DC dimming for those who might be sensitive to regular PWM dimming. It can also push up to a maximum brightness of 2,500 nits, but we suspect this will be achievable in small patches during HDR video playback.
For a complete multimedia experience, Motorola has put more effort into the speakers as well. They are tuned by Dolby Atmos and support Dolby Head Tracking.
A fairly average 4,500 mAh battery keeps the lights on, but capacity isn’t everything. We’ll see if Motorola’s hardware and software tweaks can compensate for the smaller-than-usual battery pack. It is good that Edge 50 Ultra is equipped with 125W wired charging and 50W wireless charging.
The Motorola Edge 50 Ultra also has two significant hardware advantages over some of its competitors. It supports ultra-wideband connectivity (a feature only seen on a handful of Android smartphones) and USB 3.1 gen 2 with DisplayPort 1.4 compatibility. It works well with Motorola’s Ready For desktop environment.
Software
Of course, the Edge 50 Ultra runs on the latest Android 14 with Motorola’s own features. Motorola offers productive AI capabilities for wallpaper customization purposes, but other than that, AI is almost non-existent in Motorola’s current software.
However, the OEM insists on implementing system-wide AI algorithms that work in the background. AI-based algorithms are supposed to optimize performance, battery life, and search.
Camera
Undoubtedly, one of the main features of Edge 50 Ultra is its camera. Motorola hosted a special press event in Morocco where we had a chance to try out the pre-production Motorola Edge 50 Ultra unit along with the rest of the Edge 50 lineup. The camera samples here were all taken over the course of a day at locations and events organized by Motorola.
Front camera: 50 MP, f/1.9, 1.28 µm, AF. 2160@30fps
When it comes to camera hardware, the Ultra stands out in the Edge 50 family with a total of four powerful cameras. The main camera uses a large 50-megapixel 1/1.3-inch sensor with a wide f/1.6 aperture and stabilized optics.
Examples of original Daylight cameras

The 64-megapixel telephoto camera has a 3x optical zoom and f/2.4 aperture.

And the secondary secondary camera is a 50-megapixel ultra-wide unit with a wide 122-degree FoV, f/2.0 aperture, and autofocus support for macro shots.

The selfie camera is impressive, at least on paper, with a 50-megapixel resolution, f/1.9 wide aperture, and autofocus support. It’s 2024 and we hardly ever see phones with AF-equipped selfie cameras, so kudos to Motorola for adding this feature.
Selfie photos
But not only the hardware of the camera itself, its software features and optimization as well. Although AI isn’t the main focus on the software side, Motorola benefits greatly from AI-based camera optimizations.
Let’s start with the action shot. The camera software automatically increases and adjusts the shutter speed in low-light environments to minimize motion blur. We did a brief test of the feature and found that in some cases, the shutter speed went from 1/50 to 1/200, while at the same time, the ISO doubled from 3100 to 6200. This is without any significant increase in noise thanks to the AI-based noise reduction algorithm. Here is a short example.
Examples of action shots
Adaptive stabilization works in video mode and dynamically adjusts the level of stabilization based on your hand movement and scenario.
Autofocus tracking is another video-based feature that improves the sharpness of footage from subjects moving quickly through the frame. This one will be available with the next update.
It’s worth noting that Motorola offers a choice between natural and auto-enhanced shooting modes, with the former being the default mode. Auto-enhancement mode apparently takes longer to capture images, but we didn’t notice a slowdown when using it. . Also, this isn’t exactly a Motorola exclusive. This is actually the Auto Enhance feature that we all know from the Google Photos app. Motorola decided to integrate this feature into the camera app for convenience, but the system only saves “enhanced” photos, not “normal” photos.
It’s a bit early to comment on the camera quality as we took samples with the pre-production unit. But before we get a production-ready phone, let’s take a look at some videos taken with all the cameras.
Summary
As always, it’s a little early to say whether the Motorola Edge 50 Ultra is a good buy or not, but it’s certainly a promising one. The phone has all the features of a true flagship phone, while the price starts at €999, which is considered affordable in today’s flagship segment. Over time, the price will come down and the phone will become a more attractive option.
In any case, despite the promising hardware, the full review will reveal whether the 4,500 mAh battery is enough for reliable endurance, and it will be interesting to see how the new camera system stacks up against the competition. The Moto Edge 50 Ultra is expected to hit the market by the end of May, and a lot can change between now and then.

Design and display
Both Galaxy A55 5G and Galaxy A35 5G use the design language of Galaxy S24. It is for this reason that these two models are very similar in appearance. However, last year we saw that Samsung’s mid-range to flagship phones were all similar in terms of design, and the difference was seen in the hardware and build quality.
The Galaxy A55 5G uses metal and Gorilla Glass Victus+, which is an excellent specification for a mid-range device. The A35 also has a glass back frame without Gorilla Glass protection and a plastic frame. The most obvious difference between these two phones in terms of design and build quality is related to the material of their frames, which we see in the bigger brother, the A55, which this year has used a brushed aluminum frame.
Continuing the comparison of A55 and A35, we should mention that in terms of size, both are almost similar. The Galaxy A55 5G is slightly slimmer and lighter. The Galaxy A35 5G is about 4 grams heavier, but the difference is barely noticeable.
Both phones have IP67 water and dust resistance. This means that both phones are equally resistant to dust and water. Admittedly, that’s a step down from the IP68 certification found on many Samsung phones, but in the phone category, it doesn’t matter much if you can drop the phone deeper.
Regarding the port and buttons, we should mention that a new curve can be seen on the right side of the phones. This new design on the right edge of these two phones makes it easier to recognize the location of the buttons during use. In addition, it has helped to make the phone comfortable. Above this section, there are power buttons and volume buttons. There is also a USB Type-C port on the bottom edge that you can use to charge phones using the cable in the box. Of course, don’t expect that there is any charge inside the box. In recent years, Samsung has generally removed the charger from its product box and only offers a charging cable.
Galaxy A35 5G and Galaxy A55 5G both have 6.6-inch screens and in terms of screen dimensions, both are slightly larger than last year’s version. This is for those who are interested in bigger phones; It is good news. Although the difference compared to last year is only 0.2 inches, this change has made both of these phones feel more premium to the user.
The rest of the display specifications are very close. Each earphone was equipped with Super AMOLED screens and a maximum refresh rate of 120Hz, which provide a very smooth and smooth experience in the user interface and playing games.
Performance and software
Both the Galaxy A55 5G and Galaxy A35 5G are based on Samsung’s mid-range Exynos chips. These two models use Exynos 1480 and Exynos 1380 chips respectively. Considering the history of Gegenios chips and the fact that these chips are mid-range anyway, they should not be compared with the new versions of Snapdragon.
With mid-range Exynos chips in last year’s Galaxy A54 and Galaxy A34, they provided average and acceptable performance. The Galaxy A54 came with the same Exynos 1380 and now the same chip is used in the A35.
Predictably, the Galaxy A55 5G beats the Galaxy A35 due to its faster Exynos chip. According to various benchmark tests, the Galaxy A55 outperforms the Galaxy A35 in both GeekBench 6 and 3DMark. This means that Samsung’s new mid-range chip has improved performance compared to last year’s version.

As for memory and storage, both devices are available in three versions. You can get the Galaxy A55 5G with 8GB of RAM and 128GB or 256GB of storage. The Galaxy A35 5G comes with 128GB of storage and either 6GB or 8GB of RAM, although a 256GB version with 8GB of RAM is also available for purchase.
Both of these phones came with Android 14 and One UI 6.1 and get up to 4 years of Android updates and 5 years of security updates.
Comparison of A55 and A35 phones in the camera department
Both the A55 5G and Galaxy A35 5G have triple cameras, but you’ll be using two of those lenses roughly 99% of the time. Why? Because the third lens is for macro photography. Samsung has been using this macro lens in its phones for several years. Although many users don’t use this lens, the company has decided to stick with it instead of using an efficient telephoto lens. We hope to see this change in mid-range phones in next year’s models.
In terms of specifications, the main difference is in the ultra-wide megapixels of the Derby. The Galaxy A55 5G comes with a 50-megapixel main camera and a 12-megapixel ultra-wide camera; While the Galaxy A35 5G is equipped with a 50-megapixel main camera and an 8-megapixel ultra-wide camera. Both phones also have the same 5-megapixel macro camera as mentioned. The main camera of this phone is the same. So most of the photos you’ll take in this mode are similar, but the A55’s ultra-wide shots are better. However, the difference is not so great.
On the front, the Galaxy A55 5G has a 32-megapixel selfie camera. In contrast, the Galaxy A35 5G has a 13-megapixel selfie camera. In terms of quality, the Galaxy A55 5G performs better, but the difference between the photos is not much at first glance. In the portrait mode, the separation of the subject from the background is better in A55. In contrast, the photos of A35 in portrait mode look a little artificial.
Main camera
In terms of quality, we can’t see any major differences between the Galaxy A55 and the Galaxy A35.
Ultra-wide camera
Night photography
The zoom capability of the camera on both devices is not very good, so it is recommended to do zoom photography only when necessary. Otherwise, you may be disappointed with the result. Although 2X digital zoom is suitable for photography, but when you increase the zoom value, the quality of the photos will drop drastically.
Speaker and fingerprint sensor
In terms of sound quality, the A54 and Galaxy A34 weren’t flawless, but both the Galaxy A55 5G and Galaxy A35 5G nailed many of the issues. The Galaxy A55 5G has slightly better sound quality than the Galaxy A35, but the difference is very small and you can tell the difference after listening to the same sound several times. But the sound of A55 is a little louder than A35.
The fingerprint sensor is not the best in any of the phones, but the result is satisfactory. The speed of fingerprint recognition in the A55 phone is half a second faster than the cheaper model.
Battery life and charging
Both phones have 5,000 mAh batteries, which is a standard battery capacity. Of course, the A55 and the Galaxy A35 5G are different in terms of performance due to the difference in the processor, and the A55 has a better performance in this field.
According to the PCMark benchmark that we took to measure the battery life of these phones, the A55 recorded half an hour more screen time. However, this half hour may not be felt in real and daily use.
Conclusion
In this article, we compared A55 and A35 phones. As you have seen in different parts of this article, the biggest difference between these two phones is their frame and camera performance. Although A55 has a more powerful chip, it does not make a difference in the user interface experience. Both of these phones can handle popular games well. The aluminum frame of the A55 phone is one of the advantages of this phone, which can be very important for users. Due to the price difference, these two phones do not show special performance in the A55 model, although, in the video recording department, the A55 phone provides better output due to having a much better stabilizer.
