The “Device memory is full” notification on Samsung Galaxy smartphones blocks the saving of new photos, causes application crashes and a serious slowdown in the One UI system due to a critical lack of free space in the internal storage.
Users often wonder where exactly what gigabytes disappear and why memory disappears so quickly. The answer lies in the way modern applications and multimedia work. Cameras are becoming more powerful, shooting video in 4K, and social networks are caching gigabytes of temporary files to quickly load the feed. Understanding the structuring of space is the first step to solving the problem. In this article, we will look at specific steps to free up space on devices. Samsung.
Don’t panic and immediately run to the store for a new phone. In most cases, the situation can be corrected using software methods without losing important data. We'll look at built-in optimization tools, manual cache clearing, working with cloud services, and proper use of memory cards. Following the instructions will help restore your smartphone to its former speed and free up valuable gigabytes for new tasks.
Diagnostics: analysis of occupied space
Before deleting files at random, you need to determine exactly what is eating up your memory. The system Android provides detailed statistics, but smartphones Samsung have their own unique tool for this. Log in Settings → Device maintenance → Storage. Here you will see a color chart that clearly shows the distribution of the data. Usually the lion's share is occupied by applications, images and videos, but sometimes the “Other” folder becomes a surprise.
Pay attention to the “Applications” section. Often messengers like Telegram or WhatsApp unnoticeably accumulate terabytes of correspondence and sent media files. By clicking on a specific application in the list, you can see the details: how much space is occupied by the installation file itself, and how much is user data and cache. Application cache These are temporary files that speed up the operation of apps, but over time can grow to unimaginable sizes without bringing real benefit.
If you find, If the “Images and Videos” category takes up more than half of the memory, it’s worth checking the folder DCIM i Downloads. Often, screenshots, unsuccessful duplicate photos, and files downloaded from the Internet that you have long forgotten about accumulate there. The built-in file manager My Files (My files) allows you to sort content by type and date, which greatly simplifies the search for “heavy” objects.
⚠️ Attention: Before bulk cleaning of folders, be sure to check their contents. Deleting system files or important documents from root directories can lead to data loss or malfunctions of some apps.
For a deeper analysis, you can use the “Storage Analysis” function, which will suggest deleting unused applications or duplicate files. The system itself will tell you which apps you have not opened in the last few months. This is a great way to find “digital junk” that is just lying around.
- 🔍 Check the "Downloads" section - installation APK files are often stored there, which are no longer needed after installing apps.
- 📊 Pay attention to the size of the social network cache - it can reach several gigabytes even with moderate use.
- 🗑️ Use the built-in cleaning advisor in the device maintenance menu to automatically search for large files.
Using Samsung’s built-in optimization
The company Samsung has integrated into the shell One UI a powerful maintenance module that allows you to quickly free up space in a couple of clicks. This tool not only deletes files, but also analyzes the state of the system as a whole. To run it, go to Settings → Device maintenance and click the "Optimize Now" button. The system will automatically close background processes, check security and clear unnecessary files.
The “Memory” section inside the maintenance menu deserves special attention. There is a "Clean Now" button here, which removes temporary files and leftovers from uninstalled applications. It is important to understand the difference between a full cleanup and a selective cleanup. Automatic mode is safe for the system, but it may not remove large media files that you forgot in your downloads folder. Therefore, after automatic optimization, a manual check is recommended.
The “Delete unused applications” function is a real lifesaver for those who like to install games “to try.” The smartphone will show a list of apps that you have not used for a long time and offer to uninstall them. This is an effective way to regain several gigabytes of free space without the risk of deleting something important. Uninstallation in this case, it goes through completely, removing both the cache and application data.
Enable the “Auto-optimization” function in the device maintenance settings so that the phone itself clears the cache and closes background applications at night time when you are not using it.
Also in this menu you can find settings for managing application permissions. Sometimes apps take up space because they have access to persistent data storage in the background. Limiting background activity for rarely used services will help not only save memory, but also extend battery life.
| Type of cleaning | What is removed | Security | Efficiency |
|---|---|---|---|
| Automatic optimization | Temporary files, background processes | High | Medium |
| Clearing application cache | Temporary app data | High | High |
| Removing unused applications | Full package of apps and data | Medium (needs checking) | Very high |
| Cleaning the Downloads folder | Downloaded files user | Low (risk of deleting what you need) | High |
Clearing cache and messenger data
Messengers are the main “eaters” of memory on modern smartphones. Telegram, WhatsApp i Viber save every received photo and video to local storage, even if you have already viewed them once. Over time, this collection can take up 10, 20 or more gigabytes. The easiest way to solve the problem is to use the built-in cleaning tools inside the applications themselves.
In Telegram go to Settings → Data and memory → Memory usage. Here you will see a “Clear Telegram Cache” button. Don't be afraid to click it: it won't delete your conversations or sent files from the cloud. If necessary, you can download any photo or video from the chat again by simply opening it. These are temporary filesthat take up space only for quick offline access.
With WhatsApp the situation is a little more complicated, since the correspondence history is stored locally. Go to Settings → Data and storage → Storage management. The application will show a list of chats that take up the most space. You can select a specific conversation and delete only media files (photos, videos, voices), leaving text correspondence untouched. This allows you to free up space while saving important information.
⚠️ Attention: Clearing application data (not to be confused with clearing the cache) will completely reset the app. You will lose your chat history if you haven't made a backup copy in advance. Be extremely careful with the “Erase data” button in Android settings.
It is also recommended to disable autosaving of media to the gallery. In the messenger settings, find the “Save to gallery” option and disable it. Now the received images will not be duplicated in the system folder DCIM, which will significantly slow down the filling of memory in the future. This simple setting saves hundreds of megabytes every month.
☑️ Clearing messengers
Working with the gallery and cloud storage
Photos and videos in high resolution - the most volumetric category of data. Modern flagships Samsung film in excellent quality, but one minute video in 4K can weigh hundreds of megabytes. It becomes impossible to store all this on an internal drive. The solution is to transfer the archive to the cloud or to external media.
Service Google Photos comes pre-installed on most devices and offers a convenient Free Up Space feature. Once you are sure that all your photos have been uploaded to the cloud (the cloud icon with a check mark), click on your profile avatar and select “Free up space.” The application will delete from the device those copies of photos that are already securely stored on Google servers. You can view them at any time via the Internet.
An alternative is to use a proprietary cloud Samsung Cloud or integration with OneDrive. In the gallery settings, you can enable synchronization so that new pictures are automatically sent to the cloud. This creates the effect of endless memory: old photos are archived, and only the latest photos for the month or year remain on the phone, depending on your settings. Synchronization requires a stable Wi-Fi connection.
If you don’t trust the clouds or don’t have unlimited Internet, use a computer. Connect the phone to the PC with a cable, select the file transfer mode (MTP) and manually copy the folders DCIM and Pictures to your hard drive. After double-checking, delete the originals from your phone. This is the most reliable way to create a local backup and instantly free up tens of gigabytes.
How to set up automatic photo uploading?
Go to the Google Photos application, click on your profile avatar → Photo Settings → Backup. Make sure the switch is active. To save space, select the "Express" (compression) mode, if the perfect quality of each pixel is not critical to you.
Transferring applications and files to an SD card
Many models Samsung support the installation of microSD memory cards, which is an excellent solution to the problem of lack of space. However, simply inserting a card is not enough - you need to configure the system correctly. First, transfer all media files. Open the application My files, hold down the folder with photos or videos, click "Move" and select the path SD card. This will instantly free up internal memory.
The situation with transferring applications is more complicated. Starting from version Android 6.0, the Adoptable Storage function appeared, but Samsung often disables it in its firmware to ensure stability. However, some apps allow you to manually change the data storage location in their settings. Go to Settings → Applications, select the app and see if the “Change” button is active in the Storage section. If it is gray, transfer is impossible without superuser rights.
Even if applications cannot be transferred entirely, you can configure the camera and voice recorder to save files directly to the card. In the Camera application, click on the settings gear and find the “Save location” option. Select SD card. Now all new photos and videos will be recorded directly to external media, without taking up a single byte of internal memory. This is a critical setting for owners of large capacity cards.
⚠️ Warning: Memory cards are less reliable than internal flash memory. Do not store the only copy of important documents on them. In addition, applications from an SD card may be slower, especially if the card is of a low speed class (below Class 10 or UHS-I).
For maximum efficiency, use UHS-I or UHS-II cards with a capacity of 64 GB or more. It is better to format the card using the phone itself: Settings → Device maintenance → Storage → SD card → Format. This will ensure compatibility of the file system with the shell One UI.
Radical measures: resetting and removing system garbage
If none of the above methods helped and memory fills up literally before our eyes, perhaps a deep software glitch or “garbage” from long-deleted applications has accumulated in the system. In this case, you can consider the option of returning to factory settings. This is an extreme measure that will delete absolutely all data from the phone, returning it to the “as from the store” state.
Before performing a reset, be sure to create a full backup via Samsung Smart Switch to your computer or to the cloud. To perform a reset, go to Settings → General settings → Reset → Reset data. The phone will reboot and begin the cleaning process. After turning it on, you will have a clean system with the maximum amount of free memory. This often solves problems with brakes and strange behavior of the storage.
There is also a hidden section cache partition, clearing which is safe for user data. To enter recovery mode, turn off the phone, then hold down the button combination (usually Volume up + Power or connecting to a PC via a cable for new models). Select item Wipe cache partitionfrom the menu. This will delete temporary system files that may have been damaged after the software update.
Resetting to factory settings is a 100% guarantee of freeing up memory, but requires careful preparation of a backup, since it will be impossible to restore data deleted without a copy.
After the reset, install applications selectively. Do not restore all apps from an old backup at once, as you may return the problem along with the data. It is better to set up your phone again, installing only the necessary software. This will help you understand which application caused memory leaks in the past.
Why is the memory full immediately after cleaning?
If you cleaned your phone, but after an hour the memory is full again, most likely the culprit is an application with an error (bug) that creates circular logs or a cache. It is also possible that synchronization of large amounts of data from the cloud is enabled. Check which application is most active in the background immediately after launch.
Is it possible to delete the Android folder?
No, deleting the entire folder Android is absolutely not allowed. Application data (obb and data) is stored inside it. Removing it will cause games to stop launching and apps to be reset to their original settings. You can only delete the contents of a folder cache inside it, and it is better to do this through the system settings.
Does full memory affect Internet speed?
Indirectly - yes. When memory is full, the system has no place to create temporary files to buffer web pages and stream videos. This can lead to the browser freezing and slow loading of content, although the speed of the connection itself from the telecom operator does not change.
How often should you clear the memory on Samsung?
It is recommended to carry out preventive cache cleaning and deleting unnecessary files once every 1-2 months. Built-in auto-optimization does this daily, but manual monitoring of the “Downloads” folder and instant messengers should be carried out regularly to prevent critical filling.
Is it true that memory cards slow down the phone?
If the memory card is very slow (cheap, old standard), then yes, accessing it can cause the interface to slow down if applications are installed on it or The gallery database is stored. Use only high-quality cards from trusted brands (Samsung Evo, SanDisk Extreme) with a high speed class.
