Smartphone Samsung Galaxy A10, despite its popularity and reliability, often faces the problem of lack of internal memory. This is due to modest factory specifications: only 32 GB of physical space, of which only about 20 GB is available to the system and pre-installed applications. When you run out of free space, your device starts to slow down, apps crash, and downloading new files becomes impossible. Understanding how to properly manage storage is a critical skill for the owner of this gadget.
In this article we will analyze all the available methods for freeing up space: from simple actions that every user can do, to advanced system settings. You will learn which files can be deleted safely, how to transfer data to a memory card, and why standard cleaning tools are not always effective. The correct approach to maintenance internal memory will extend the comfortable life of your smartphone.
Analysis of storage capacity
Before you start deleting files, you need to clearly understand what exactly is taking up space on your disk. Android provides built-in visualization tools, but they don't always show the full picture. Go to menu Settings → Device maintenance → Memory. Here you will see a color chart where images, videos, audio, documents and applications are indicated in different colors.
It often turns out that the lion's share of space is occupied not by the applications themselves, but by them cache data and downloaded media files from instant messengers. For example, Telegram or WhatsApp can quietly store gigabytes of viewed photos and videos in hidden folders. It is also worth paying attention to the “Other” section, which sometimes swells to incomprehensible sizes due to residual files of remote apps or system logs.
For a more detailed analysis, it is recommended to use third-party utilities, such as Files by Google or DiskUsage. They display the memory structure in the form of rectangles, where the size of the figure corresponds to the size of the file. This allows you to instantly find “heavyweights” that are hidden deep in system directories and are not visible in standard Explorer. This approach helps identify forgotten downloads or duplicate photos.
⚠️ Attention: Be extremely careful when using third-party disk analyzers. Do not delete files from system folders (for example
Android/dataorsystem) unless you are 100% sure of their purpose. This can lead to unstable operation of the operating system.
Deleting cache and application data
The fastest way to free up space is to clear the cache. Cache are temporary files that applications create to speed up their work. Over time, these files accumulate and can take up hundreds of megabytes. It is important to distinguish between the concepts of “Clear cache” and “Clear data”. The first removes only temporary garbage, the second resets the application to factory settings, deleting logins and saves.
To perform cleaning, go to Settings → Applications. Choose an application that takes up a lot of space (often browsers, social networks or YouTube). Click on the item Memory, and then the button Clear cache. For system applications, such as Google Play Services or Samsung Internet, this procedure is absolutely safe and will not lead to the loss of personal data.
Particular attention should be paid to instant messengers. In the settings itself WhatsApp or Telegram there are “Data and Storage” sections where you can delete the media file cache. This is more effective than cleaning through the system menu, since it deletes copies of pictures and videos that you have already viewed. Regularly performing this procedure can free up up to 1-2 GB of space monthly.
Clear the Chrome browser cache every 2 weeks. It saves copies of all pages visited, which quickly eats up memory on devices with low storage capacity.
If an application does not work correctly or takes up an abnormally large amount of space even after clearing the cache, you can try resetting its data. Remember that after clicking the button Clear data you will have to re-enter your passwords and configure the application. Use this function only as a last resort or before uninstalling a app to make sure that it does not leave any “tails” in the system.
Transfer applications to a memory card
Model Samsung Galaxy A10 supports installation of microSD memory cards up to 512 GB. This is a salvation for users suffering from a lack of internal 32 GB. Unfortunately, not all applications can be transferred - it depends on the desire of the developer and the type of app. System utilities and widgets usually remain on the internal drive, but games and heavy apps can often be moved.
The transfer process is as follows: open Settings → Applications, select the desired app and press the button Memory. If transfer is possible, the Changebutton will be active there, allowing you to select SD card as the main storage location. After confirmation, the system will move the files, which may take several minutes depending on the size of the application.
- 📱 Move to the first First of all, heavy games with graphic content, they take up the most space.
- 📸 Set the camera to save photos and videos directly to the memory card through the settings of the Camera application.
- 📂 Use the memory card as the main storage for documents, music and downloaded files from the browser.
It is worth considering that the speed of applications installed on the memory card is slower. may be lower than when installed in internal memory, especially if a cheap card with a low write speed (class 4 or 6) is used. For comfortable work, it is recommended to use standard cards UHS-I Class 10 or higher. Also keep in mind that when you remove the card, applications will no longer launch.
☑️ Preparing to transfer data
Cleaning the Downloads folder and junk files
Folder Download (Downloads) is the most common place where digital garbage accumulates. Users often download APK installation files, PDF documents, pictures from the Internet and forget about them. These files can sit for months, taking up valuable space. Regular revision of this directory should become a habit.
Open the application My files (standard Samsung Explorer) and go to the Downloadssection. Sort files by size or date. Remove all application installers (.apk) that you have already used - they are no longer needed. Also check the folder Bluetoothwhere files received from other devices are often automatically saved.
| File type | Where to look | Can I delete | Note |
|---|---|---|---|
| Installers (.apk) | Download folder | Yes | After installing the application file useless |
| Temporary files (.tmp) | Different folders | Yes | Remains of app operation |
| Error logs (.log) | System/Log | With caution | Needed only for diagnostics |
| Thumbnails (.thumb) | DCIM/.thumbnails | Yes | Deleted automatically, but can be done manually |
Another the source of garbage is a folder .thumbnails in a directory DCIM. This is where thumbnails of your photos are stored for the gallery. If you have thousands of pictures, this hidden folder can grow to several gigabytes. It can be safely deleted, but the system will create it again the next time you open the gallery. As a radical solution, some users create a stub file in this folder to prevent the system from writing data there, but this can slow down the gallery.
⚠️ Attention: Before mass deleting files from the “Downloads” folder, carefully check their contents. There may be important receipts, tickets or work documents that you downloaded a week ago and forgot.
Using cloud storage
When physical memory is exhausted, the best solution is to transfer data to the cloud. Services like Google Photos, Yandex.Disk or Dropbox allow you to store an unlimited amount of media content on remote servers. This frees up the local space of the smartphone, leaving access to files via the Internet.
The most convenient tool for Android owners is Google Photos. Enable the "Backup and Sync" feature in the application settings. Once all your photos are uploaded to the cloud, use the “Free up space” function. The application will automatically delete from the device those photos and videos that are already securely saved in your Google account.
For other types of files (documents, archives, music), you can use file managers with cloud support or a standard application Google Drive. Upload important files there, make sure they are accessible from another device, and then delete the originals from your phone. This is especially true for work projects and personal archives that you would hate to lose, but which are rarely used.
What to do if there is no Internet to upload to the cloud?
If you do not have access to Wi-Fi or mobile traffic is limited, connect your phone to your computer via a USB cable. Copy large files (videos, photos) to your PC hard drive, and then delete them from your phone. This is the fastest way to free up gigabytes of space without consuming Internet traffic.
Reset settings to factory settings
If none of the above methods helped, and the memory is full of incomprehensible system files, the only option is a complete reset (Hard Reset). This procedure returns the smartphone to the condition it was in when purchased out of the box. All user data, applications and settings will be permanently deleted.
Before starting the procedure, it is critical to make a backup copy of all important data. Save contacts to your Google account, transfer photos to your computer or cloud, remember passwords for important services. Go to Settings → General settings → Reset → Reset data. Confirm the action and wait for the reboot.
After the reset, the system will be clean, without garbage, cache and residual files accumulated over the years. You can set up your phone again, installing only the applications you really need. This often solves not only the memory problem, but also eliminates many software errors and interface brakes, making Samsung Galaxy A10 fast and responsive again.
A complete reset is an extreme measure, but the most effective. It guarantees the removal of 100% of junk and hidden files that cannot be found manually.
Frequently asked questions
Why is memory not freed after deleting applications?
This happens because applications leave behind folders with data, cache and configuration files. To completely clear space, you need to go to the file manager and manually delete folders with the names of deleted applications, or use the “Clear data” function before deleting.
Is it possible to delete Samsung system applications?
You cannot delete system applications (for example, Samsung Health, Bixby, Samsung browser) using standard means; the “Delete” button will be inactive. They can only be "Disabled", which will hide them from the menu and stop operation, but will not free up significant memory. Complete removal requires obtaining root access, which is not recommended for ordinary users.
Is it safe to use cleaning applications (Clean Master and similar)?
Most of these applications work aggressively and can delete the necessary files. In addition, they themselves consume resources and display advertisements. The built-in device maintenance tool from Samsung is quite enough to safely clear cache and garbage without the risk of damaging the system.
How to transfer WhatsApp to a memory card?
The WhatsApp app itself cannot be transferred to a memory card; it will always be in the internal memory. However, you can transfer media files (photos, videos, voice messages). In the WhatsApp settings, select “Data and storage” and specify the save path to the SD card, or manually move the folder WhatsApp/Media via Explorer.
What is “Other” in the storage and how to clear it?
The “Other” section usually contains system update files, temporary data, cache of streaming services (Netflix, Spotify) and offline map data. You can clear it by deleting the cache of specific applications that downloaded content, or by resetting the settings of navigation applications (for example, Yandex.Maps or Google Maps) to factory settings.
