Series smartphones Samsung Galaxy, despite powerful hardware and an optimized One UI shell, over time they inevitably face a lack of free space. This is due to the accumulation of system junk, the growing size of modern applications and the increasing resolution of the photos and videos we take every day. When the internal storage is almost completely full, the device begins to work slower, lags appear in the interface, and cameras may refuse to save new pictures.
Users often wonder which files can be deleted without risk to the system, and which are better left. In this article, we will analyze not only standard cleaning methods through settings, but also the hidden capabilities of the operating system Androidavailable to device owners Galaxy S, Galaxy A i Galaxy Z. You will learn how to effectively manage cache, transfer heavy media files, and use cloud services to offload your device.
Freeing up memory is not a one-time event, but a process of regular maintenance of your gadget. A competent approach to data storage will extend the life of your smartphone and maintain its high performance over several years of use.
Analyzing storage fullness and searching for large files
The first step before cleaning is to accurately diagnose what exactly is taking up space. Built-in tools Samsung provide detailed statistics, but for in-depth analysis it is better to use specialized utilities or a built-in file manager. Go to Settings → Device maintenance → Memoryto see the overall picture of the distribution of data by category: applications, images, videos, audio and documents.
It often turns out that the lion's share of space is occupied by forgotten downloads or messenger caches, which automatically save all received media files. Using third-party disk analyzers, such as DiskUsage or the built-in Files by Google analysis mode, allows you to visualize memory occupancy in the form of a block map. This helps to instantly find hidden folders with gigabytes of unnecessary data that are not displayed in the standard gallery.
Pay attention to the folder Download and directory DCIM/.thumbnails. The latter contains thumbnails of your photos and can grow to several gigabytes if you have a large media library. Deleting these files is safe, the system will recreate them as needed, but this will instantly free up space.
⚠️ Attention: When deleting files through third-party analyzers, be extremely careful with system folders whose names you do not know. Deleting files from directories
Android/dataorAndroid/obbcan lead to resetting the settings of games and applications.
Clearing the application cache and system reset of temporary files
The application cache is temporary data that apps save to speed up their work. Over time, this cache can reach enormous sizes, especially in social networks and browsers. Clearing the cache does not delete your personal data, logins or passwords, but it forces the application to reload information from the network, which can temporarily slow down its launch.
There is a convenient tool for mass clearing in the shell. One UI here. Go to Settings → Device maintenance → Memory and click the Clear nowbutton. The system will automatically delete temporary files that have not been used for more than 30 days. However, for deep cleaning of specific applications, for example Telegram or YouTube, it is better to go into the settings of each of them separately.
Inside Messengers often have their own memory management tools. For example, in Telegram you can configure the media file cache to be automatically cleared after a certain period of time. This prevents the repeated accumulation of gigabytes of watched videos and pictures.
- 🗑️ Go to
Settings → Applications, select a heavy application and pressStorage. - 🧹 Press the button Clear cache, but do not confuse it with the "Clear data" button.
- ⚙️ In the browser Chrome or Samsung Internet go to history and delete downloaded files and image cache.
- 📱 Check your auto-upload settings in the gallery and disable saving high-resolution thumbnails if this option is available.
Use the Unlimited Storage mode in Google Photos to automatically upload photos to the cloud and then delete them from your phone's memory with one button.
Clearing your cache regularly should become a habit, especially if you actively use streaming services. Video services cache large portions of video, which quickly eats up free space. If you do not plan to watch this video again offline, feel free to delete the cache.
Managing media files and using cloud storage
High-resolution photos and videos shot on modern matrices Samsung Galaxytake up a colossal amount of space. One minute of 4K video can weigh over 300MB. It is impractical to store this entire collection in internal memory, especially on models with basic storage capacity.
The most effective solution is to transfer the media archive to the cloud or to an external storage device. The service Google Photos offers the "Free up space" function, which finds pictures already uploaded to the cloud and deletes their local copies. Similar functionality is available in OneDrive, which is deeply integrated into the ecosystem Samsung.
For users who prefer local storage, a memory card would be an ideal option. microSD. Devices of the series Galaxy A and some flagships of the previous generation have a slot for it. You can configure the camera so that all new pictures and videos are saved directly to the card, bypassing the internal memory.
| Storage method | Advantages | Disadvantages | Recommended capacity |
|---|---|---|---|
| Internal memory | High read/write speed | Limited volume, expensive | 128 GB and higher |
| microSD card | Cheap, easy to expand | Lower speed, risk of breakdown | up to 1 TB |
| Cloud (Google/OneDrive) | Access from any device, security | Internet required, paid subscription | Unlimited (by tariff) |
| External SSD (USB-C) | Very high speed, reliability | Need to be carried with you, price | 500 GB - 2 TB |
How to transfer photos to an SD card in bulk?
Open the "My Files" application, hold your finger on the DCIM folder, select "Move" and specify the path to the memory card. This is faster than transferring each photo separately through the Gallery.
Removing unused applications and optimizing games
Applications are the second largest category of memory consumers after media files. Many users install apps “just in case” and forget about them, while they continue to take up space and sometimes run in the background. Revision of installed software is a mandatory stage of optimization.
Go to the section Settings → Applications and sort the list by size. You'll be surprised to find games you haven't played in six months that take up 5-10 GB each. Modern games often download additional resources after installation, and this data is not always deleted along with the application itself during standard deletion.
For games that you want to save but rarely use, check for the archive function. Some launchers and game managers allow you to compress unused resources or upload them to the cloud. It is also worth paying attention to the “light” versions of popular applications, for example Facebook Lite or Google Go, which take up much less space.
⚠️ Attention: Before deleting system applications that can be deactivated (but not deleted without root access), make sure that they are not used by other services. Disabling a system component can lead to unstable operation One UI.
- 📉 Remove duplicate applications (for example, two browsers or two players).
- 🎮 Check the download folders inside game launchers for old versions of resources.
- 🚫 Disable pre-installed software (bloatware) that you do not use, through the app menu.

Using a memory card and the Adoptable Storage function
Owners of smartphones Samsung with memory card support have a powerful means of expanding memory. However, it is important to understand the difference between using the card as portable storage and as part of internal memory. In modern versions Android on devices Samsung the function of combining the card with internal memory (Adoptable Storage) is often hidden or disabled by the manufacturer to ensure stability.
However, you can configure the memory card as the main storage location for photos, videos, music and documents. When you insert a new card, the system will prompt you to select a method of use. Select the "Data Transfer" option or configure it manually in the storage options. This will allow applications that support working with the SD card to save their data to it.
It is important to choose cards of a high speed class, for example UHS-I U3 or V30. Slow cards can become a bottleneck for the system, causing slowdowns when launching applications installed on them or when recording high-definition video.
A memory card is ideal for storing media files, but installing heavy applications and games is best left to the fast internal drive for maximum performance.
If your model does not support memory cards, consider using flash drives with interface USB Type-C. By connecting such a drive via an adapter or directly, you can instantly transfer archived files to it, freeing up gigabytes of internal space.
Advanced methods: Developer mode and cleaning via ADB
For experienced users who have exhausted standard methods, there are deeper cleaning methods. Developer mode in Android gives access to settings for limits on background processes and animations, which indirectly affects the speed of work when memory is full, but also allows you to manage the cache more flexibly.
One of the most effective tools is the utility ADB (Android Debug Bridge) on your computer. By connecting your smartphone via USB and turning on debugging, you can run a command to clear the cache of all applications at once, including system ones that are usually inaccessible to the user. This is especially useful if the system writes "Memory full" but visually the files are not found.
adb shell pm trim-caches 999999999This command instructs the package manager to trim cache files across all apps to free up the specified amount of space (in this case, a very large number to clear as much as possible). Use this method with caution as it will cause apps to take a little longer to load when first launched.
⚠️ Warning: Using ADB commands requires USB debugging mode to be enabled. Do not connect your phone to untrusted computers with debugging enabled to avoid unauthorized access to your data.
You can also limit the background activity of applications in developer mode. Find the item "Background process limit" and set the value to "No more than 2-3 processes." This will prevent the accumulation of temporary data by many apps running in the background.
What to do if the memory is full of “System”?
Often this is a display error or accumulation of logs. Try rebooting into safe mode (hold down the power button, then long-tap on the “Shut Down” icon). If space is freed up, the third-party application is to blame.
Frequently asked questions (FAQ)
Why is the space not freed up after deleting files?
Check the trash in the "Gallery" and "My Files" applications. Deleted files are often moved there and stored for another 30 days. It is also possible that the application cache was automatically restored immediately after clearing.
Is it possible to delete the Android folder on a memory card?
No, this cannot be done. The folder Android/data on the memory card stores the cache and data of applications that you have configured to work with the SD card. Removing them will reset the settings of games and apps.
How to transfer applications to a memory card on a Samsung Galaxy?
Go to Settings → Applications, select the desired application. If the developer has allowed the transfer, there will be a "Change" button in the Storage section where you can select the SD card. If there is no button, transfer is not possible.
What is "Other" in the phone storage?
The "Other" category usually includes system files, cache, application data that did not fall into the main categories, and sometimes files with an unknown extension. Clearing the cache and deleting old software updates helps reduce this partition.
Does filling the memory affect the charging speed?
There is no direct effect on the charging speed, but when the memory is critically full, the system is unstable, the processor may overheat due to constant work with the file system, which indirectly affects the power consumption and heating of the device.
