Use Samsung Gallery more professionally with these tricks

Note that all the features and tricks mentioned in this article are not available in all Samsung phones and the features may vary depending on the phone model.
Samsung Gallery Search Tricks
Now, to search and find the photo you want, just type whatever you remember from the photo. For example, your photo can be of a specific subject or a screenshot of a site. For such cases, you need to type the type of subject or site name, and Samsung Gallery will show you interesting results.
In the following, for a better understanding, we will show you all the smart search methods. To enter the Samsung search or search gallery, once you open the app, tap the magnifying glass icon at the top.
Search based on the text inside the photo
If there is a certain text in the photo you want, just type it and the gallery will find every photo with such text using artificial intelligence. For example, we searched for the word Galaxy, and photos containing the word appeared, even photos with the word Galaxy in their watermark!
In another example, we searched for the word Zoomit and found similar results; That is, any photo in which the English word “Zoomit” is present in any way.
Search by date
If the number of photos in the gallery is large and you only need photos with a certain date or you want to find photos taken in a certain period of time, you should enter the desired date in the search section of the gallery in any way that is convenient for you and find all the photos of that date.
Various methods of filtering results based on date can be based on entering the full date as a number to view photos of a specific day or simply displaying photos related to a specific month by writing the name of the month and year.
Search by subject
One of the best ways to search for photos is to find photos tagged with subjects that are in the image, and Samsung Gallery does this for you in the best way.
For example, we searched for the word Cats to find photos we took of cats. After this work, the artificial intelligence of the Samsung gallery suggested different breeds of cats for a more detailed search, of course, we settled on the same Cats, but such a suggestion shows the accuracy of the gallery’s performance in finding photos!
Then we searched for the word Flower, which in turn showed us a gallery of every photo we had taken of flowers. Samsung Gallery supports a wide range of different subject search inputs, from objects to food types.
You can also use the Documents tag to search for documents or any photo that looks like a paper document, and QR to find photos that contain barcodes or QR codes.
Search based on location and weather
In the previous section, we mentioned the location; That is, you can find photos that have been recorded in a specific location. Of course, to use such a method, you must have previously activated location recording in the camera program, and then search for the name of the place, region, or city.
Also, if you’re looking for photos with specific weather conditions that prevailed in them, you can search for the desired weather conditions in addition to the location tag. For example, we searched for Cloudy weather to display photos of cloudy days. Then we added the location of Tehran to find all the photos of cloudy days in Tehran.
Search by content type
When we talk about the type of content, it means how the photos and videos were recorded. According to the software and hardware capabilities of its cameras, every Samsung phone can take photos or videos with modes such as night mode or slow motion.
To find such media, just search for the name of the desired mode in the relevant section. For more guidance, look at the different modes in the third photo. By typing any mode, you can easily find the desired photos.
Search for screenshots by writing the name of the application
If you took a screenshot of a certain app and now it’s lost in a pile of photos, just search for that app’s name. We searched the Snap and Phone app names to find the corresponding screenshots. The interesting thing is that the gallery also found other photos for us with the desired keywords.

For example, in the photo on the left, a phone and in the photo on the right, a photo of a phone with the Snap app in it is also found as search results, which shows the strong performance of Samsung Gallery’s artificial intelligence.
Search based on multiple filters
If the photo contains multiple searchable attributes and tags extracted by AI from within the photos, the gallery will display another tag to narrow down and get you to the final result(s) to filter the results more precisely, after selecting one tag. , the selection of these filters will continue until you finally find the photo you want.
For example, first, we search for the name of a subject, and then we are shown the location tag, which by selecting it, we can see only the photos related to that location (according to the images you saw above). Next, other filters may be shown, such as date, type of photo or video, category, and other filters, which are available at each stage of filter selection.
In addition, the searchable filters in the gallery are not limited to the ones mentioned in this article and countless filters are available. For example, you can use Notes to find notes and Receipts to find purchase receipts.
Various features of Samsung Gallery
One UI’s gallery features are not only limited to search but also have something to say in the field of media editing and management.
Find the site address from the screenshot
When you take a screenshot of a site with any browser, the details of that site are stored in the photo’s metadata, which you can access in the gallery.
When you open the desired screenshot, you will be faced with the Go to website option at the very beginning, by clicking on it, you will be easily redirected to the site from which you took the screenshot. You can also tap the details option or swipe up to enter the photo details section, where you can also see the site name.
Attractive offers of Samsung Gallery
As we said in the previous section, Samsung Gallery can provide suggestions for different photos individually or in groups, which includes editing and editing them to improve the quality of the photo. Pay attention to the photos below.
In the photo on the left, we went into the details of a photo and, as in the previous section, we see suggestions that include remastering and blurring the background of the photo. According to the type of photo registration, the suggested options can be different from the following options:
- Colorize: Colorize black and white photos
- Long Exposure: converting moving photos into images with high exposure time (for example, light trails of moving cars at night)
- Remove Moire: Removing visual disturbances created from photos taken from screens
- 24h Time-lapse: convert photos with a landscape theme into a sunrise-to-sunset time-lapse video.
- Remaster: improve photo quality in terms of blur, noise, detail, color, contrast, etc
- Erase Shadows: remove shadows detected in the photo
- Erase Reflections: Remove reflections detected in the photo
- Background Blur: Creating a bokeh effect for portrait images or images containing human and animal faces
If you want to see other suggestions available for your photos, on the main gallery screen, tap the hamburger option at the bottom right, and then select the Suggestion option.
After entering it, you will be faced with various offers, an example of which you can see in the photo on the right. The suggestions you receive can include deleting extra photos, editing photos and videos, and removing duplicate images and unnecessary documents.
Separate the subject from the background
The ability to separate the subject from the background is now available in many gallery apps, and Samsung Gallery is no exception. To isolate the subject, open the photo and hold on the desired subject for a few seconds. The subject is now separated from the background. You can copy it or use it as a sticker by holding it and navigating to the desired app.
If you want to use the aforementioned feature more professionally, after separating the subject, don’t take your hand off it, and with another finger, open any program you want and leave the desired subject there for use.
Slow-motion videos
The slow-motion video feature is not available for all Samsung phones and is only enabled on flagship phones that use Galaxy AI. To use this feature, play any video you want and then hold your finger anywhere in the video for a few seconds. The video will then go into slow motion until you take your finger off the screen. The mentioned feature will work better when you have recorded the video with a higher frame rate.
Ability to add tags to photos
You can add tags to photos to make them easier to find. The tags you add will appear as suggested search options in the search section, which you can easily find the desired photo by tapping on.
Go to the photo details or swipe up on the photo to add a tag. Now touch the Add tag option at the bottom of the screen and then add any tag you want to your photo.
Extract text from the photo
Now you can take a photo of any text you want and Samsung will extract it from the photo for you. The mentioned feature also supports the Farsi language, which is good news for Farsi-speaking users of the Galaxy ecosystem.
To do this, open your photo and tap on the yellow option with the letter T at the bottom right of the photo. After that, the gallery will detect the texts in the photo and you can tap to copy each one.
Grouping similar photos
Another convenient feature that is more useful for busy galleries is grouping photos that are very similar to each other. To use it, first, tap the Pictures tab in the bottom bar to display all the photos in one place, then tap the three dots option at the top right and select the Group Similar Images option.
Samsung gallery hidden settings (Gallery Labs)
If you want to unlock more features of Samsung Gallery, you need to activate Gallery Labs by doing a few steps. This section, which shows the experimental features of the gallery and is part of the hidden settings of the Samsung phone, opens features such as locking albums, saving photos in bulk as PDF files, changing the default mode of displaying videos, and many other features.
- Go to Settings and tap on the last option, About Gallery.
- Then tap on the gallery version multiple times to see the Gallery Labs activation message.
- Go back to the Settings page to find the Gallery Labs option under the About Gallery option.

Font recognition from photos online
Online font detection sites are the best way to find a font from a photo, and almost all of them work the same way. To use these sites, it is enough to enter one of these sites using your phone and upload your photo so that it recognizes the font used in the image in a short time. In the following, we introduce some of the best online sites for recognizing fonts from photos:
FontSquirrel
FontSquirrel is one of the best online font recognition sites that, in addition to font recognition, allows you to download different fonts and chat with other people in the FontTalk section.
Working with the FontSquirrel website is easier than you might think. You just need to enter the site, upload the desired photo, and give the site a few seconds to display the photo font and other similar fonts for you. To upload a photo on this site, you can drag and drop the photo or tap on the Upload option and select the photo from your image gallery.
After uploading the photo on the FontSquirrel site, you will be asked to specify the part of the text that you want the font program to recognize, and finally, click on the Matcherate it button to provide you with the fonts that match the image.
The great thing about FontSquirrel is that it also allows you to purchase the provided fonts, and if you’re lucky, you might be able to download some of them for free.
Fontspring

The best artificial intelligence tool to find fonts from photos
These days, when the fever of artificial intelligence is hot everywhere in the world, the use of artificial intelligence to recognize fonts from photos is one of the most important concerns of many people in the world.

This website has two web versions, free and pro, and using artificial intelligence and 840,000 commercial and free fonts, it displays more than 60 types of similar fonts for every image you upload.
Try to have the photo you upload as high quality as possible; Because sometimes the low quality of the photo makes WhatFontIs unable to identify the corresponding font. Also, after uploading the image, the website tries to separate the letters automatically; However, if you want to identify broken fonts, you need to separate each letter with an advanced image editor.
Recognizing the text font from the photo on the computer and laptop
In addition to the online tools that you are not limited to using on your phone and computer, there is a lesser-known feature in Photoshop that can recognize fonts from photos for you.

How to reduce the use of Chrome
Chrome browser has always been considered one of the most popular browsers and the main RAM killer of computers since its release until now. It doesn’t matter if the RAM capacity of your system is 4 GB or even 32 GB and more; In any case, by opening Chrome, you will dedicate most of the RAM capacity to Chrome.
Although Google has always been trying to optimize the use of Chrome and periodically improves the stability and consumption of hardware resources of this browser with frequent updates, RAM consumption is still one of the biggest problems for users when using Chrome.
This issue becomes more pronounced when you connect your Google account to Chrome to sync information, extensions, and history, and at this time you will see that at least half of the RAM capacity is easily allocated to this browser.
In general, it is inevitable that a large part of the system resources will be used to use this browser, but with solutions, this effect can be greatly reduced, especially in the case of RAM consumption.

Enable Memory Saver in Chrome
Nearly two years ago, Google introduced the Memory Saver feature to reduce Chrome’s RAM consumption. This feature intelligently disables tabs, add-ons, and other processes that remain unused for a while and do not refer to them, deletes their data from the RAM, and has a significant impact on the RAM consumption of this browser. To enable this feature:
- Enter Settings from the three-dot option at the top of the screen.
- Search for a Memory saver in the search bar above.
- By activating the RAM saver, three levels, Moderate, Balanced, and Maximum, will be displayed, and by choosing each, you can determine the period of time for the tabs to be disabled. By selecting Balanced, the tabs will be disabled after a normal amount of time of inactivity. If you select Moderate, the tabs will be disabled for a longer time, and with Maximum, they will be disabled for a very short time after leaving.
If your RAM fills up quickly and slows down the system, use the Maximum option; However, closing unused tabs is a more logical solution.
If your RAM is not affected much by Chrome, we recommend leaving the setting on Balanced so that when the tab returns and activates, less time is spent on reloading the page and refreshing the cache, thus reducing the processing load.
Prevent tabs from being disabled for a specific site in Chrome
If you have opened an important site that has certain information or is involved in a process that is lost if the tab is disabled, you can prevent it from being disabled by adding the address of this site to the list of exceptions and keeping it open all the time.
- In Chrome settings, from the top search bar, search for inactive.
- Click on the Add option in the Always keep these sites active section.
- You can choose your desired site from the open tabs or enter the desired website address manually from the Add Sites section.
Close unused and high-use tabs
Perhaps Chrome is always accused of high RAM consumption, but the user himself can also be guilty in this case; Therefore, it is better to manage your open tabs and if you are one of those people like me who thinks you should keep tabs open to refer to them every hour or day, you will never see the empty half of the device’s RAM.
For more convenient RAM management, Chrome allows you to see the RAM consumption of each tab by hovering the mouse over the tabs, and thus you can make an easier decision by closing the tabs that are consuming the most RAM.
If you don’t see the RAM usage information by hovering over each tab:
- Open Settings and enter Appearance from the left bar.
- Activate the Show tab memory usage option from the Tab hover preview card section.
Remove or disable unused plugins
Chrome is not just a browser and provides a platform for running various applications and extensions so that as a multi-purpose software, various tools and facilities can be used. This browser has a lot of codes and many complications, part of this complexity is due to the existence of many features and facilities, and most importantly, the infrastructure of the ChromeOS operating system is based on Chromium.
Chrome extensions are so wide and diverse, and among them, there are useful tools that there is rarely a situation where the user of this browser does not install an extension; But sometimes the number of installed add-ons becomes so large that the user loses track of the number and does not notice the increase of add-ons that may have been used only once.
Therefore, if you are one of the people who have many extensions in Chrome, it is better to fix this section and help increase the speed of Chrome and thus reduce its RAM consumption. For this:
- First, through Chrome’s Task Manager, check which extensions occupy the most RAM; To do this, press Shift+Esc.
- Click the Memory footprint tab a few times until an upside-down triangle icon appears next to it.
- Tabs, processes, and add-ons will be shown in order of RAM consumption, and in this way, you can identify the most consuming add-ons.
- Click on the three dots option from the top menu and click on manage extensions from the Extensions section.
- On the add-ons page, turn off frequently used or underused items or remove them completely from Chrome by clicking Remove.
Disable Preload Pages
Chrome has a feature that preloads some sites and pages before the user requests to speed up the page-loading process when the user wants to enter a site.
This feature will be useful for people who have weak internet and it even reduces the processing load of the processor to a great extent, but it will lead to an increase in RAM consumption another way to prevent this is to turn off the mentioned feature:
- In the Chrome settings, search for Preload from the top toolbar and turn off the Preload Pages option.
- You can also balance the level of preloading pages by Chrome and enable Standard Preloading instead of Extended Preloading.

Close Chrome completely and disable background activities
Sometimes, by closing the Chrome window, the processes of this browser do not stop completely and Chrome remains open in the background so that it can be opened faster in the next execution of Chrome. Of course, some extensions and applications that do not deal with tabs and operate independently of Chrome can lead to Chrome’s activity in the background and, as a result, increase RAM consumption.
If you don’t want this app to keep running in the background when you’re not using Chrome:
- Open the settings and enter System from the left menu.
- Turn off the Continue running background apps when Google Chrome is closed option.
In this article, we explained the most important tricks to reduce Chrome consumption; However, with some initiatives, it is possible to reduce Chrome’s RAM consumption even more. If you know or have tried a specific method or trick that has been fruitful and effective for you, share it with us in the comments section.

How to hide a file or directory in Linux?
Most of us have files on our computer or laptop that we don’t want other people to see. If your system uses a Mac or Windows operating system, you can use various tools to hide different files and folders or even encrypt your favorite files to better protect your privacy. In this article, we will talk about how to hide a file or directory in Linux.
In Linux computers and laptops, like Windows and Mac, you can hide your favorite files and directories from the view of others both through the terminal of the operating system and by using some tools that are very easy to use. In the following, we will introduce some efficient methods to hide files and directories in Linux.
Hide files and directories through the terminal
The easiest way to hide various files and directories in Linux is to use the Linux terminal or the Linux graphical environment (GUI).
- Open a Linux terminal window by pressing Ctrl+Alt+T.
- In the terminal, type the following command:
Note: instead of sync.ffs_db, you must enter the name of the file you want and then type the file name again with a dot (.) at the beginning.
To hide the file through the graphical environment (GUI) of Linux, proceed as follows:
- First, right-click on the desired file and click on the Rename option.
- Put a dot (.) at the beginning of the file name.
- Open and close the file once to apply the changes and hide the file.
Hide files in an image
Although hiding the file and directory in Linux by changing the file name seems to be a simple and fast method, but equally, it becomes easy for people who are a little familiar with the Linux environment to access this file. Therefore, we suggest that you go for a better method.
Data encryption or steganography is a method of hiding information in a normal image file, which, like the first method, has almost simple steps, but unlike it, it really hides the files you want from anyone’s view, and you can even hide them after hiding them. Delete the original file in the image irretrievably. In the following, we will teach the steps to hide the file and directory in an image file using the Linux terminal.
- Open the Linux terminal and create a new folder (directory) using the following command.
Note: instead of newdir, enter your desired name for the new directory.
- Copy or move the image file (PNG or JPG) you want to use to hide your desired file into the new folder you created.
Important note: sometimes, depending on the size of the files or the number of files you want to hide in an image, you may need to use a large image so that you have enough space to store the files inside the image.
If you want to hide multiple files, it is better to compress them into one zip file. To compress files in Linux, you must first create a new folder.
- To create a new folder inside the folder you have already created, enter the following command in the Linux terminal:
Note: instead of tmp, you must type the name of the folder you created in the previous step and enter your desired name for the new folder instead of newdir.
In this tutorial, we created a main folder named Images, which contains an image named MainImage.png and a subfolder named FileToHide. This subfolder contains all the files we want to hide.
- To compress your files into a zip file, run the following command in the Linux terminal:
Note: The r- code in the above command includes all the subfolders in the specified folder in the compressed file. In this command, instead of secret.zip, replace the desired name; You should also enter the name of the folder where you have saved all the files you want to hide instead of FileToHide.
To hide the zipped file in your desired image, run the following command in the Linux terminal:
Note: In this command, MainImage.png is our main image file and secret.zip is the name of the zip file that contains all the files we want to hide. In fact, we redirected these two files to a new image file called secret.png. Be careful that the names of MainImage and secret (in both files with PNG and zip extensions) should be replaced with the names you want.
- After running this command, if you want to see a list of all the files in the folder, use the ls command. In this directory, you will see the file name of the new image you created.
- To access files hidden in an image file, use the following command to extract the zip file from within the image:
Note: replace secret.png with the name you chose for the image file containing the secret files .
- When you run the ls command , the root folder containing the files you zipped will be displayed.
- In this case, if you want to see the original files, enter the following command in the terminal:
Delete the original file after hiding it in the image
Sometimes you may want to delete the original version of the file after hiding the sample files you want in an image file. You can use the shred command to do this. This command replaces the file value with a specific value when the file is deleted. For example, we can set the file value to zero when deleting a file.
- For this purpose, after opening the Linux window, run the following command:
By default, these files are overwritten three times (meaning rewriting new information, without the ability to recover previous information). This amount is usually enough, but if you want to overwrite the file more often, you only need to enter the command as follows and replace N with the number of times you want the files to be overwritten.
In this command, the z-code replaces the value of the file with the value zero. Also, the remove- code removes files; Of course, this is done through the shred command itself, but without entering remove- in the shred command, the file removal operation will not be done completely.
What method do you use to hide your files in Linux? We will be happy if you share your experiences in this field with us and other Zomit users.
