The problem of lack of internal storage is perhaps the most common challenge faced by owners of devices based on Android. Tablets Samsung Galaxy Tabdespite advanced shell optimization One UIover time inevitably accumulate gigabytes of temporary files, application caches and forgotten downloads. When the memory full indicator turns red, the system starts to slow down and new applications refuse to install.
There are many myths about how to effectively deal with this problem. Some users immediately rush to remove system applications, others download dubious “accelerators” from the store, which only worsen the situation. In this article, we will look at professional and safe ways to free up space using built-in tools Samsung and proven manual methods that are guaranteed to restore the performance of your device.
Analysis of occupied space and system tools
Before you start deleting files, you need to understand what exactly is “eating up” your memory. Modern versions Android on tablets Samsung have a built-in excellent storage analyzer. It allows you to visualize your data and pinpoint the categories that take up the most space. Usually this is video, photos or a cache of instant messengers.
To start the analysis, go to Settings → Device Maintenance → Storage. Here you will see a pie chart of the data distribution. The system will automatically suggest deleting unused files, but manual control often gives better results. Pay attention to the “Applications” section: sometimes one forgotten game can take up more than 5 GB, although you haven’t launched it for months.
The built-in maintenance utility also allows you to perform quick optimization with one click. However, it is worth understanding that this function primarily frees RAM (RAM), closing background processes, and does not clear persistent storage. Deep cleaning of the internal drive requires a more detailed approach to each category of files.
⚠️ Attention: Do not blindly rely on the “Optimize Now” button in the maintenance menu. It often misses large files in the Downloads folder and the social media cache, which make up the lion's share of used space.
Clearing the application cache and deleting temporary files
Cache is temporary data that applications save to speed up their work. Over time, these files can grow to gigantic sizes, especially in browsers, YouTube and social networks. Clearing the cache is a safe procedure: it does not delete your logins, passwords or personal correspondence, but only resets temporary buffers.
To clear the cache selectively, go to Settings → Applications. Select an application that takes up a lot of space (for example Chrome or Telegram), go to the Storage section and press the Clear cachebutton. Do not confuse this button with the “Clear data” option, which will completely reset the application to its factory state, deleting all your settings and authorizations.
If you want to delete the cache of all applications immediately, you can use the recovery menu. Hold down the power button and volume up button to enter Recovery mode (the tablet must be turned off), but on working devices it is easier to use the developer menu or specialized scripts via ADB, although for the average user this is redundant. The easiest way is to go through the top 5 heaviest applications manually.
- 🗑️ The browser cache often takes up from 500 MB to 2 GB, if you have not cleared history and Cookies for a long time.
- 📱 Messengers save thousands of viewed pictures and videos in hidden cache folders.
- 🎮 Games can store temporary update files that are no longer needed after installation.
Periodically clear the cache of YouTube and Instagram applications, as they aggressively save video previews and news feeds, taking up hundreds of megabytes per week of active use.
Working with the “Downloads” folder and user files
Folder Download (Downloads) is a “black hole” in the memory of most tablets. PDF documents, APK installation files, pictures from the Internet and forgotten video files are automatically saved here. Users often download something important, use it once and forget to delete the file that has been there for years.
Open the application My files (My Files), which is preinstalled on all devices Samsung. Go to the "Downloads" category. Sort files by size or date. You will be surprised to find installation files for application updates that have been installed for a long time, or old versions of documents.
Pay special attention to files with the extension .apk. Once the application is installed, this file is no longer needed. Storing duplicate installers not only takes up space, but also poses a potential security risk if the file was downloaded from an untrusted source. Feel free to delete anything that is older than a month and is not a critical document.
| File type | Average size | Recommendation |
|---|---|---|
| APK installer | 50–200 MB | Delete after installation |
| Video (MP4) | 100 MB - 2 GB | Transfer to card or cloud |
| Documents (PDF) | 1–10 MB | Keep only current ones |
| Archives (ZIP/RAR) | 50–500 MB | Unpack and delete the original |
Optimization media files and galleries
Photos and videos are the most voluminous data on any mobile device. Modern tablet cameras shoot in high resolution, and one minute video in 4K can weigh several hundred megabytes. Storing the entire media library in the internal memory becomes economically unprofitable and technically impractical. Samsung Galaxy Tab They are filmed in high definition, and one minute-long 4K video can weigh several hundred megabytes. Storing the entire media library in internal memory becomes economically unprofitable and technically impractical.
Use the “Free up space” function in the application Gallery. Artificial intelligence Samsung finds blurry pictures, similar duplicates and old screenshots and suggests deleting them. This is a quick way to get back a few gigabytes without manually sorting through thousands of photos. Also check the folder Trash (Trash) in the gallery - deleted photos are stored there for another 30 days, taking up space.
For long-term storage, it is advisable to set up automatic uploading of photos to cloud services, such as Google Photos or OneDrive, which are deeply integrated into the ecosystem Samsung. After successful synchronization, you can use the “Free up space” function, which will delete local copies of photos, leaving them available for viewing via the Internet.
Hidden media folders
Messengers often create hidden .thumbnails folders where thumbnails of viewed images are stored. These folders can grow to gigabytes. To find them, turn on the display of hidden files in the My Files application settings and check the Android/media and DCIM paths.
Transferring data to a microSD memory card
Most mid- and high-price tablets are equipped with a memory card slot Samsung mid- and high-price segments are equipped with a slot for memory cards microSD. This is the most efficient way to expand storage without deleting data. Correctly setting up the card allows you to transfer heavy media files and even some applications to it.
Insert a memory card and format it as internal storage (if the Android version allows it) or as portable storage. In the second case, you need to manually transfer the files. Go to Settings → Device maintenance → Storage → Memory card and select the data transfer option. The system will offer to move photos, videos and documents.
Applications are more difficult to transfer. Not all developers allow installation of apps on external media due to reduced reading speed. However, in the settings of each specific application (in the Storagesection) there may be a Editbutton that allows you to transfer it to an SD card. If there is no button, the application must remain in the internal memory.
⚠️ Attention: When formatting a memory card as internal storage, all data on it will be permanently deleted. In addition, such a card will be encrypted and cannot be read on other devices or a computer without a special reset.
☑️ Preparing the memory card
Deleting unused applications and widgets
Each installed application not only takes up space for its installation file, but also creates additional folders with data, cache and libraries. Even if you don't launch the game for months, it can receive background updates and take up precious megabytes.
Check your installed software. Go to Settings → Applications and sort the list by frequency of use or size. Remove everything you haven't used in the last 3 months. Pay special attention to pre-installed software (bloatware) from telecom operators or partners Samsungwhich often cannot be removed in the standard way, but can be disabled.
To disable a system application, select it in the list, press Disable. This will hide the application from the menu and stop all its background processes, effectively freeing up system resources, although the disk space may be reduced slightly. To completely remove system applications, you need superuser rights (Root) or use ADB, which is not recommended for ordinary users.
Regular audit of installed applications (once a quarter) is the best prevention of memory shortage. Delete what you don’t use without waiting for the disk to become critically full.
Specific problems of messengers and social networks
Messengers like Telegram, WhatsApp i Viber are the main “eaters” of memory on Android tablets. They automatically download all media files from chats and groups. Without proper configuration, such a messenger can take up more than 10 GB of space in a month of active correspondence.
In settings Telegram go to the section Data and Memory → Memory Usage. Here you can set a limit on the cache size and configure automatic cleaning of old files. For example, set a rule: “Delete media that has not been opened for more than 3 days.” This is a revolutionary change that keeps the application size within 200-300 MB.
In WhatsApp the situation is similar. Go to Settings → Data and storage → Storage management. The application will show the chats that take up the most space and allow you to selectively delete sent videos and pictures. Often in general chats, heavy videos are sent that no one needs, but take up space for all participants.
⚠️ Attention: Messenger interfaces are frequently updated. If you do not find the specified menu items, use the search inside the application settings using the keywords “Memory”, “Cache” or “Storage”. The logic of the settings remains the same, even if the names of the partitions change.
Radical measures: Reset to factory settings
If none of the above methods helped free up enough space, or if the system is unstable due to file fragmentation, the last option remains - a hard reset Reset). This procedure will return the tablet to the state it was in immediately after purchase.
Before performing a reset, it is critical to create a complete backup of all data. Use Samsung Cloud, Google Drive or copy the files to your computer. After the reset, all personal data, accounts and applications will be deleted without the possibility of recovery.
To perform a reset, go to Settings → General settings → Reset → Reset data. Confirm the action and enter the unlock password. The tablet will reboot and begin the cleaning process, which may take from 10 to 30 minutes depending on the storage capacity. After turning on, you will receive a clean system with the maximum amount of free space.
An alternative to resetting
Before a full reset, try simply deleting and reinstalling the heaviest applications. This often solves the problem of bloated cache and database errors without having to erase all personal photos and contacts.
Why is the space not immediately freed up after deleting files?
This is due to the operation of the trash can in the My Files and Gallery application. Deleted files are moved to temporary storage for 30 days. To free up space instantly, you need to go to the trash and empty it completely.
Is it possible to delete the Android folder on a Samsung tablet?
No, you absolutely cannot delete the folder Android entirely. It stores data from all installed applications. Deleting this folder will lead to incorrect operation of apps, loss of game saves and reset of settings. You can only clear subfolders cache within specific applications.
How to transfer applications to a memory card if the button is inactive?
If the “Change” button is inactive, then the application developer has prohibited installation on external media. It is impossible to bypass this restriction without root access. In this case, you can transfer only media files (photos, videos, music) to the memory card by creating the corresponding folders there.
Does filling the memory affect the speed of the tablet?
Yes, directly. When the free space is less than 10% of the total, the Android system starts having difficulty creating temporary files and swapping. This leads to noticeable interface slowdowns, long application launch times and possible freezes.
Is it safe to use cleaner applications from the Play Market?
Most of them are useless or even harmful. They take up space themselves, display intrusive advertisements and create the illusion of bustling activity. The built-in tools Samsung and Android are quite sufficient for competent cleaning without the risk of deleting the necessary system files.
