Smartphone Samsung Galaxy A10 is one of the most popular budget models of past years, but its built-in 32 GB storage fills up at lightning speed in modern realities. Reinstalling the system often seems like the only solution, but in fact there are many ways to restore your device to its former speed without losing valuable data. When the internal memory is full to capacity, the phone begins to slow down, applications crash, and notifications about lack of space appear with alarming regularity.
In this article we will look in detail at how to effectively free up space on your gadget, using both built-in tools One UIand third-party methods. We won’t just delete files at random, but will approach the process systematically, starting with an analysis of what exactly is taking up gigabytes. Proper optimization will extend the life of your device for a long time.
Analyzing storage fullness
The first step to solving the problem is to understand exactly where the free space has gone. The shell One UI ot Samsung has an excellent monitoring tool that clearly shows the distribution of data. You should not rely on guesswork - the system itself will tell you what type of content is the main “eater” of gigabytes.
To start the analysis, you need to go to the menu Settings and select the item Device maintenance. Here you will see a color chart, where applications, images, videos, audio files and documents are indicated in different shades. By clicking on any of the sectors, you will be taken to a detailed menu for managing this particular type of data. This allows you to specifically remove unnecessary things without affecting important system files.
⚠️ Attention: If the “Miscellaneous” or “Other” section takes up an abnormally large amount of space (more than 5-7 GB), this may indicate accumulation of the system cache or residual files from remote apps. In this case, simply emptying the trash will not help; a deeper approach will be required.
Often users do not notice that old application updates or downloaded offline maps take up gigantic amounts of space. Regularly checking this section should become a habit, especially if you actively use instant messengers and social networks. Memory control is not a one-time action, but a process of maintaining the health of the device.
Deleting cache and temporary application files
The fastest way to get a few hundred megabytes of free space is to clear the cache. The cache is temporary data that applications store to speed up their work, but over time it bloats to enormous sizes. On Samsung A10 this procedure is performed securely and does not delete your logins, passwords or correspondence.
You can clear the cache for each application manually through the settings. Go to the Applicationssection, select a heavy app (for example, YouTube, Instagram or Chrome) and click on the item Storage. There you will see two buttons: “Clear data” and “Clear cache”. We need exactly the second option. Clicking on it will instantly free up space occupied by temporary thumbnails, loaded pages and the playback buffer.
- 🗑️ Clearing the browser cache deletes download history and temporary website files, speeding up the Internet.
- 📸 The cache of the gallery and social networks often contains thousands of thumbnails of viewed photos, which can be safely deleted.
- 🎮 The game cache can take up several gigabytes if the game has not been updated for a long time or was installed incorrectly.
There is also a mass clearing function through the maintenance menu. The system itself will offer to delete unused files if they are not needed for the apps to work correctly. However, it is worth remembering that after clearing the cache, applications may take a little longer to load when first launched, since they will have to regenerate temporary files. This is normal behavior Android operating system.
Use the "Clean Now" function in the "Device Maintenance" section once a week to prevent temporary files from filling up the memory critically.
Transfer photos and videos to a memory card
Media files - this is the main source of memory filling on any smartphone, and Galaxy A10 is no exception. The good news is that this model supports the installation of memory cards microSD up to 512 GB. Transferring the gallery to an external drive is the most effective solution for those who like to shoot a lot of videos and photos.
To transfer files, open the application My files, which is Samsung's standard file manager. Go to Internal storage, find the folder DCIM (photos from the camera are stored here) and Pictures. Select the desired folders or individual files, click the menu (three dots) and select Move or Copy. Then go to the Memory card section and paste the files there. After successful transfer, the originals in the internal memory can be deleted.
| Type data | Default location | Recommended action | Save space |
|---|---|---|---|
| Photo from camera | DCIM/Camera | Transfer to SD | High |
| Screenshots | Pictures/Screenshots | Removing unnecessary ones | Medium |
| Downloads from the browser | Download | Archiving or deleting | Medium |
| Video from instant messengers | Android/Media | Setting up autosave | Very high |
It is also important to set the camera so that new pictures are immediately saved to the memory card. Go to the application Camera, click on the settings gear and find the item Save location. Switch it to Memory card. Now all new frames will be automatically recorded to external storage, leaving the internal memory free for the system and applications.
☑️ Transferring media files
Optimizing the operation of instant messengers
Messengers like WhatsApp, Telegram i Viber have an insidious feature: they save every photo and video received to the phone’s memory, even if you just glanced at it in a chat. Over time, the folders with media files of these applications grow to tens of gigabytes, quietly eating up all the free space on Samsung A10.
In Telegram the situation is resolved most elegantly thanks to the cloud-based nature of the messenger. Go to Settings applications, select Data and memory, and then Storage usage. Here you can set a cache size limit (for example, 200 MB) and configure automatic cleaning. If you set the auto-delete period to 3 days, the application itself will delete old media files from the device, leaving them available in the cloud for re-downloading if necessary.
With WhatsApp things are more complicated, since it stores everything locally. Inside chats, you can go to information about a contact or group, click Media, links and documents and manually delete heavy videos. Also in the WhatsApp settings there is an item Storage and data -> Storage managementwhere the system will show the most voluminous chats. This allows you to precisely delete gigabytes of useless postcards and forwarded videos without deleting the correspondence itself.
⚠️ Attention: Before mass clearing media files in messengers, make sure that important documents or work photos are already saved in another location. Automatic deletion in Telegram is reversible (the file can be downloaded again), but manual deletion in WhatsApp without a backup may be irreversible.
Another useful tip is to disable autosaving to the gallery. In the settings of both instant messengers, you can prevent automatic saving of received media to a shared folder on your phone. This will prevent duplication of files: they will only be located inside the application, and not copied to the system gallery, taking up double the volume.
Why do instant messengers take up so much space?
Messengers create copies of all files for quick access. In addition, they store message databases and index files, which become fragmented and increase in size over time, especially if there is a lot of forwarded content in chats.
Deleting unused applications and games
Often, apps that you have not used since purchase have been lying on your smartphone for years. Games weigh especially a lot - modern projects can take up 2-4 GB each, including a cache with textures and sounds. Getting rid of digital “junk” will not only free up space, but also reduce the load on the RAM and processor Exynosinstalled in the A10.
Go to Settings -> Applications and sort the list by size. You will immediately see the leaders in space consumption. If you see a game you haven’t played for six months, or a food delivery app you don’t use, feel free to delete it. To do this, click on the application and select the button Delete. System applications that cannot be deleted can at least be disabled so that they are not updated and do not take up space in the list.
Do not forget about the pre-installed software from the telecom operator or manufacturer, which is often called bloatware. Although Samsung A10 it is not overloaded with them as much as some other brands, there will certainly be a couple of extra apps there. Removing them or disabling them through the menu Application Settings (if available) or through the hidden developer menu can provide additional space gains.
- 🎮 Heavy games with 3D graphics take up the most space due to texture and sound resources.
- 🛒 Marketplace applications often cache product catalogs, taking up hundreds of megabytes.
- 📺 Streaming services can store downloaded movies for offline viewing that you forgot about.
If deleting the application is not possible (the button is inactive), try first clear data of this application. This will return it to the “as after installation” state, deleting all your settings and the cache inside it, which often frees up a significant amount of memory without completely demolishing the app.
Regular audit of installed applications (once a month) allows you to keep the system clean and prevents unused software from running in the background.
Resetting the settings to factory settings as a last resort
If none of the above methods helped, and the memory is still occupied by “ghost” files that cannot be found and deleted, a radical but effective method remains - a complete reset to factory settings (Hard Reset). This procedure will return your Samsung Galaxy A10 to the state it was in when purchased, completely clearing the internal memory of user data.
Before starting the procedure, it is critical to create a backup copy of all important data. Use the cloud service Samsung Cloud or Google Drive to save contacts, calendar and notes. It is better to manually copy photos and videos to a computer or memory card, since when resetting, everything in the internal memory will be irretrievably destroyed. Make sure that the battery charge is at least 50% so that the phone does not turn off during the process.
Settings → General settings → Reset → Reset dataAfter confirming the action, the phone will reboot and begin the cleaning process, which may take from 5 to 15 minutes. Upon completion, you will have a clean system. When setting up for the first time, do not restore all applications from Google backup at once, otherwise you risk returning the same garbage that clogged up the memory before. Install apps selectively, only those that are really needed.
⚠️ Attention: Resetting the settings deletes ALL data from the internal memory, including photos, contacts (if not synchronized), messages and account settings. The microSD memory card is usually not formatted in this case, but for safety it is better to remove it before the procedure.
This method also helps to correct software errors that could lead to incorrect display of the amount of free memory. Sometimes the system “thinks” that the space is occupied, although the files have already been physically deleted - a reset corrects the file system table.
Why is the space not freed up after deleting files?
Often files end up in the “Trash” inside the “Gallery” or “My Files” application. They continue to take up space until you empty the trash completely. It is also possible that the deleted file is still in use by some background process - in this case, rebooting the phone will help.
Is it possible to transfer the applications themselves to a memory card on a Samsung A10?
In modern versions of Android and the One UI shell, the ability to transfer applications (Adoptable Storage) is often disabled by the manufacturer or is unstable. Even if the function is available in the settings of a specific application, migrated apps may run slower, since the speed of memory cards is usually lower than the speed of internal flash memory.
How to clear the "Miscellaneous" folder in the storage?
The "Miscellaneous" folder contains system files, cache, application data, and files that the system could not categorize. The best way to clear it is to delete the cache of heavy applications, clear downloads and, as a last resort, reset the settings. Third-party cleaners are often powerless here.
Does filling the memory affect the speed of the Samsung A10?
Yes, directly. When the internal memory is more than 90% full, the system does not have enough space to create temporary files and swap (virtual memory). This leads to severe interface slowdowns, long application launches and possible system freezes.
