Slow operation Galaxy and constant notifications about lack of space are familiar to many users. Internal storage Android over time becomes clogged with system garbage, duplicate photos and forgotten applications, which leads to a critical slowdown of the interface. Restoring the device's functionality begins with competent diagnostics and consistent cleaning of available space.
In this article we will examine not only standard methods for deleting files, but also specific shell functions One UIthat allow you to return gigabytes of free space without losing important data. You will learn how to find hidden large files, optimize work messengers and correctly use cloud services to unload the built-in storage.
Storage diagnostics and analysis of occupied space
Before deleting something, you need to understand what exactly is taking up space on your disk. The system Samsung provides a built-in analysis tool that visualizes the distribution of data by category. Go to Settings → Device maintenance → Memoryto see a detailed diagram.
Here you will find that the lion's share is often occupied not by applications, but by their cache or media files from instant messengers. The system automatically highlights categories that can be optimized. Pay attention to the section "Other" —sometimes remnants of uninstalled apps or temporary update files are hidden there.
⚠️ Attention: Do not delete files from system folders manually through the file manager if you are not sure of their purpose. This can lead to unstable operation Android or loss of application settings.
For a more in-depth analysis, you can use third-party utilities, but the built-in tool is usually sufficient for an initial assessment. Regularly checking statistics helps you notice in time an abnormal increase in space, for example, due to a malfunction of the voice recorder or camera.
Clearing the cache and deleting temporary files
The fastest way to free up space is to clear cached data. The cache speeds up the launch of applications, but over time it grows to gigantic proportions, especially in social networks and browsers. Unlike user data, deleting the cache safe does not erase your logins or correspondence.
You can clear the cache of each application separately through the menu Applications in the settings by selecting a specific app and pressing Storage → Clear cache. However, for global cleaning it is more convenient to use the “Clean Now” function in the device maintenance menu. This action will delete temporary files that are no longer needed by the system.
- 🗑️ Delete browser cache Chrome or Samsung Internet regularly, as it accumulates gigabytes of images from visited sites.
- 📱 Clear video streaming application cache (YouTube, Netflix) if you watch content online rather than download it.
- ⚙️ Use the "Optimize" function in the maintenance menu to automatically remove background processes and junk files.
After the cleaning procedure, you will notice that The available memory has increased, and the phone began to respond to presses a little faster. If the problem of low space returns too quickly, it is possible that a particular application is not working correctly and is generating redundant logs.
Reboot your phone periodically after clearing the cache - this helps the system to correctly recalculate free space and update the file system index.
Managing multimedia and working with the gallery
Photos and videos are the main consumers of internal memory. Modern cameras Samsung record in high definition, and one minute video in 4K can weigh hundreds of megabytes. Manually sorting through the gallery takes a lot of time, so it is better to use smart sorting tools.
In the "Gallery" application, go to the menu (three bars) and select Suggestions. The system will automatically find blurry pictures, similar frames and screenshots that you haven't opened for a long time. It is also worth checking the folder "Trash"where deleted files are stored for another 30 days, continuing to take up space.
Settings → Applications → Gallery → Storage → Clear cacheIf you have enabled synchronization with Google Photos or OneDrive, use the “Free up space” function. It deletes from the device those pictures that are already securely stored in the cloud. This allows you to store the entire collection in original quality without filling up the built-in storage.
Hidden folders in the Gallery
Check the .thumbnails folder in hidden system directories. Sometimes thumbnails of deleted photos accumulate there, which can be safely deleted through a file manager with access to system files.
Optimization of instant messengers and social networks
Messengers like Telegram, WhatsApp i Viber tend to quietly absorb free space. They automatically download all pictures, videos and documents sent in chats, saving them in duplicate folders. Without configuration, these applications can take up to 10-20 GB of memory per year of active use.
Go to the settings of each messenger and find the section Data and storage. Disable automatic media downloads for group chats. Also inside the applications there are built-in memory management tools that allow you to delete files sent more than a month ago.
| Application | Path to cleanup | Recommended action |
|---|---|---|
| Telegram | Settings → Data and memory | Limit cache (300 MB) |
| Settings → Data and storage | Storage management | |
| Viber | Settings → Memory | Clear media cache |
| Phone settings → Applications | Clear application cache |
Regularly clearing attachments in chats not only frees up space, but also speeds up the search for the desired messages in the chat history. Don't forget to check the "Documents" folder, where work files from work chats are often saved.
⚠️ Attention: The messenger settings interface is often updated by developers. If you do not find the specified menu item, look for a similar section in the privacy or data storage settings.
☑️ Checklist for clearing messengers
Transferring data to a memory card and to the cloud
If the internal memory is critically low, consider expanding the storage. Many models Samsung support memory cards microSD. You can transfer photos, videos, music and documents to them, leaving the built-in memory only for the system and applications.
To transfer files, use the built-in file manager My files. Select the desired folders, select the option "Move" and specify the memory card as the target location. Some applications allow you to change the path where new files are saved in their settings.
An alternative to a physical card is cloud storage. Services like Google Drive, Yandex.Disk or Dropbox allow you to store file archives remotely. Set up automatic photo upload via Wi-Fi so that new pictures are immediately sent to the cloud and deleted from the phone.
The combination of a memory card for media files and the cloud for important documents is the most reliable long-term data storage strategy perspective.
Resetting settings as a last resort measure
If none of the above methods helped free up enough space, it is possible that critical errors or hidden system failures have accumulated in the file system. In this case, an effective solution would be to completely reset the device to factory settings.
This procedure completely deletes all user data, applications and settings, returning the phone to the “as from the store” state. Before you begin, be sure to back up your contacts, messages and important files through your account Samsung Cloud or Google.
To perform a reset, go to Settings → General settings → Reset → Reset data. Confirm the action and wait for the process to complete. After turning on, the phone will work as quickly as possible, and the amount of available memory will be restored to factory settings.
What to do if the reset button is inactive?
If the reset option is locked, check if the function is enabled “Find my device” or account protection. Sometimes you need to remove your Google account from the settings before performing a_hard reset_.
Will the firmware be deleted during a reset?
No, resetting the data only affects the user partition. The operating system version Android and installed firmware updates will remain unchanged.
Is it possible to restore data after a reset?
Without a preliminary backup, it is extremely difficult to restore data. Specialized software gives a low chance of success, so the only hope is cloud backups.
How long does the reset process take?
Usually the procedure takes from 5 to 15 minutes, depending on the amount of data and the speed of the built-in drive. Do not interrupt the power during this time.
Do I need to remove the SIM card before resetting?
Not necessary, but it is recommended to remove the memory card and SIM card to avoid accidentally formatting external media or resetting the operator's network settings.
