The smartphone Samsung Galaxy A10, released in 2019, remains a popular device due to its affordability and reliability, but over time, owners are faced with slowdowns and a lack of internal storage. The Android operating system accumulates temporary data, application cache, and remnants of uninstalled apps, which creates the effect of “digital noise” that slows down the processor. Proper cleaning of the gadget can return it to its former agility without the need to buy a new device or complex flashing.
In this article we will analyze safe and effective methods of freeing up space specifically for the model Samsung A10, taking into account the features of its file system and the One UI shell. You will learn which folders can be deleted without fear of damaging the system, how to use built-in optimization tools, and why third-party “cleaners” often do more harm than good. Let's start with an analysis of what exactly takes up precious gigabytes in the memory of your device.
Analysis of occupied space and system settings
Before you start thoughtlessly deleting files, you need to conduct a thorough diagnostics of the storage. Owners Galaxy A10 are often surprised to discover that only half of the declared 32 GB is available, and the reason lies not only in the system, but also in hidden data storage devices. Go to the menu Settings → Device maintenance → Storageto get a detailed summary of which file categories consume the most resources.
The system automatically segments data into applications, images, videos, audio and documents. Pay special attention to the “Applications” section, since messengers like WhatsApp or Telegram tend to grow to several gigabytes due to the saved media history. Cached data can constitute a significant part of the volume, and clearing them is the first logical step in optimization.
It is important to understand the difference between user files and system garbage. If you see a large volume in the Miscellaneous or System categories, this may indicate error logs or remnants from failed firmware updates. In such cases, standard cleaning may not help, and deeper intervention into the file structure through a computer or special utilities will be required.
⚠️ Attention: Do not try to delete files from system folders if you are not 100% sure of their purpose. The error may cause the phone to stop booting or lose the ability to make calls.
Using the built-in Samsung optimizer
Samsung has implemented a powerful built-in maintenance tool in its devices, which is often ignored by users in favor of third-party apps from the Play Market. For model A10 this tool is the most secure way to quickly clean up, since it has access to system partitions that are closed to regular applications. Activate it through the “Optimization” shortcut on the home screen or in the notification shade.
Press the button Optimize now, and the system will automatically close background processes, check for malware and clean up unnecessary files. The operating algorithm of the built-in cleaner takes into account the specifics of the Exynos processor installed in this model, preventing aggressive termination of important system services. After completing the procedure, you will see a report on the freed space and battery status.
For more detailed work, go to the section Memory → Clear now. Here you can manually select categories of files to delete, such as thumbnail images or advertising ID files. Regular use of this function, at least once a week, will keep performance the smartphone at a stable level without sudden drops in FPS in games.
Set up automatic optimization in the device maintenance menu so that the phone I cleared the cache on my own during idle moments, for example, at night while charging.
However, it is worth remembering that the built-in tool is not omnipotent. It will not be able to delete deep application logs or duplicate files scattered across different directories. Therefore, manually checking the storage remains a necessary step in comprehensive cleaning, especially if the device has been in active use for several years.
Manually clearing the cache and application data
The most effective way to free up space is to target the cache of heavy applications. Social networks, browsers and video players store temporary files to quickly load content, but over time this data becomes redundant. Go to Settings → Applications, select the desired app (for example, YouTube or Instagram) and click on Memory.
Here you will see two buttons: “Clear cache” and “Clear data”. The first one deletes temporary files without losing your settings and logins, which is safe and recommended to do regularly. The second button resets the application to the “as after installation” state, deleting all accounts and settings, so use it with caution only in extreme cases.
- 🗑️ Browsers: Chrome or Samsung Internet cache can take up to 500 MB, including browsing history and cookies.
- 📸 Camera: Check your camera settings on the presence of saved thumbnails or unsuccessful pictures in hidden folders.
- 💬 Messengers: In the settings of WhatsApp itself there is a “Data and Storage” section where you can delete sent media files en masse.
Pay special attention to applications that you have not used for a long time used it. In the list of applications, sort them by size or date of last use. Removing rarely used apps will not only free up space, but also reduce the load on RAM Samsung A10, which this model does not have much of by modern standards.
☑️ Weekly clearing the cache
Working with the Downloads folder and duplicate files
Folder Download (Downloads) is one of the main sources of digital waste on Android devices. Users often download APK installation files, PDF documents, images from the Internet and forget about them until the memory is completely full. To access these files, use the standard file manager My filespre-installed on Samsung.
Inside the manager, go to the “Downloads” category and carefully review the list. Delete all application installation files (.apk extension) as they are no longer needed after installation. Also check folders created by third-party apps, for example Telegram Images or WhatsApp Video, which often duplicate content from the gallery.
| File type | Extension | Recommendation | Where to look |
|---|---|---|---|
| Application installer | .apk | Delete immediately | Download folder |
| Temporary files | .tmp | Delete | Root folder |
| System logs | .log | Can be deleted | Android/logs folder |
| Photo thumbnails | .thumbdata | Clear cache galleries | Hidden DCIM folders |
Finding duplicates is another important task. Often, users save the same photos several times or download files that are already in memory. It takes a long time to manually search for them, so you can use the “Search for duplicates” function in some file managers or just visually scroll through the gallery, paying attention to similar pictures.
⚠️ Attention: Before mass deleting files from the Android/obb folder, check whether they are data for installed games. Removing them will reset your progress in games.
Cleaning the gallery and optimizing media files
Photos and videos take up the lion's share of memory on a smartphone, and Samsung A10 is no exception. This device's camera produces files of sufficient quality that it can quickly exhaust the 32GB of internal storage. Start by deleting blurry photos, screenshots, and videos that were recorded in error or are no longer valuable.
Use the Trash tool in the Gallery app. Many users forget that deleted photos go there first and continue to take up space for 30 days. Manually empty your Trash to free up gigabytes of space in no time. Also check the folder Screenshots, where images of interfaces that are no longer needed are often accumulated.
For a long-term solution to the problem, it is recommended to set up automatic uploading of photos to cloud storage, for example, Google Photos or Yandex.Disk. After a successful download, enable the Free up space feature, which will delete the originals from your phone, leaving them only in the cloud. This will allow you to store thousands of pictures without filling up the internal memory of the device.
Hidden folders in the Gallery
Service folders, such as .thumbnails, can be displayed in the gallery. They contain thumbnails for quick viewing. They can be safely deleted through the file manager, but the system will create them again over time.
Resetting settings as a last resort measure
If all of the above methods did not bring the desired result and the phone continues to slow down, the system may have accumulated critical registry errors or damage to the file structure. In this case, the only effective solution is a full reset to factory settings (Hard Reset). This procedure will return Samsung A10 to the state it was in when purchased.
Before performing a reset, it is critical to back up all important data: contacts, messages, photos and notes. Use your Samsung or Google account to sync, or connect your phone to your computer and copy the files manually. Remember that after a reset, it will be impossible to restore data without a backup.
To perform a reset, go to Settings → General settings → Reset → Reset data. Confirm the action by entering your PIN code or pattern. The process will take a few minutes, after which the phone will reboot and offer the initial setup. Do not install all applications in a row at once - install only the essentials to evaluate the cleanliness of the system.
A full reset deletes absolutely all data from the internal storage, including photos and contacts, so backup is a mandatory step.
⚠️ Attention: Make sure the battery level is at least 50% before starting the reset. Turning off the power during the process can lead to software failure.
Prevention and good habits
In order not to return to the problem of lack of memory every few months, it is worth developing several useful habits for using your smartphone. Check your storage regularly once a month, removing accumulated garbage before it becomes critical. Do not store files on your phone that can be easily found on the Internet or transferred to a computer.
Disable automatic downloading of media files in instant messengers. In the settings of WhatsApp and Telegram, you can prohibit saving received photos and videos to the phone gallery. This will prevent duplication of files: they will remain available inside the chat, but will not take up space in the general memory of the device.
It is also recommended to periodically restart the device. A simple reboot once a week helps clear RAM of frozen processes and temporary service failures. For Galaxy A10 with its modest characteristics, this is a simple but effective measure to maintain stability.
Use a microSD memory card to store photos and music, leaving the internal memory solely for installing applications and operating the system.
Frequently asked questions (FAQ)
Is it possible delete the Android folder on Samsung A10?
No, you absolutely cannot delete the entire folder Android since it stores data from all installed applications and system files. This will cause apps to malfunction. However, you can clear the contents of subfolders cache inside it if you know exactly what you are doing.
Why do you quickly run out of space again after cleaning?
Most likely, you have automatic saving of media files enabled in messengers or background photo synchronization is running. Check the settings of WhatsApp, Telegram and Google Photos, and also disable auto-downloading of application updates via the mobile network.
Do you need to install applications like Clean Master for cleaning?
For Samsung A10 this is not recommended. The built-in optimizer is quite sufficient. Third-party “cleaners” themselves often consume a lot of resources, show ads and can delete necessary files, slowing down the device instead of speeding it up.
How to transfer applications to a memory card on this model?
In modern versions of Android, the ability to transfer applications to an SD card is limited by the developers of the applications themselves. You can try going to Settings → Applications, select the app and click “Change”, but if the button is inactive, it means the application does not support transfer.
What to do if the phone says “Memory full”, although the files are deleted?
Try clearing the cache of the Media Storage application. Sometimes the system does not update the file index immediately. A simple reboot of the phone will also help, which will forcefully update the free space data.
