Slow smartphone performance, sudden application crashes and the inability to install important updates are all classic symptoms of a full storage. Device owners Samsung often encounter a situation where the system reports a critically low amount of free space, even if the user has not downloaded terabytes of movies. Understanding how the file system works and where the hidden gigabytes of garbage are hidden is the key to returning your gadget to its former performance.
In this article, we will examine not only the standard cleaning methods available to each user through the settings menu, but also delve into the specifics of the shell. One UI. You'll learn why simply deleting photos from your gallery doesn't always free up space, how the Trash mechanism works, and what system processes consume resources in the background. A competent approach to memory management can extend the life of the device by several years without the need to purchase a new model.
Let's start by analyzing what exactly is taking up space. Users are often surprised to see that the “Other” or “System Data” section has grown to obscene proportions. This could be a cache of streaming services, error logs, or temporary update files. To effectively deal with the problem, you must first carry out a full diagnostic of the storage using built-in tools or third-party utilities, which we will talk about later.
Built-in optimization and maintenance of the device
The company Samsung has introduced into its shell a powerful tool for automatic system maintenance, which many users ignore. This module is capable of independently analyzing the state of RAM and permanent memory, offering to delete unnecessary files. It is accessed through the menu Settings → Device Maintenancewhere the system displays the status of all components in real time.
When you click on the “Optimize Now” button, the phone runs a series of scripts: closes background applications, clears temporary files and scans the device for malware. However, it is worth understanding that automatic cleaning is often superficial. It removes only obvious garbage, but does not touch large files or duplicate media that require manual intervention by the owner.
It is important to regularly go to the “Memory” section inside the maintenance menu. There you will see a color chart that clearly shows the distribution of the data. The system categorizes files into applications, images, videos, audio and documents. If you see that the “Applications” category takes up the lion’s share of space, then the problem lies in instant messengers or social networks that accumulate gigabytes of cache.
⚠️ Attention: The “Optimize Now” function does not delete your personal files (photos, contacts), but can close applications running in the background. Save unfinished documents before starting the procedure.
For deeper work, use the “Clear Now” function in a specific memory section. This action is safer than a full reset, since it only affects temporary data. Regular use of the standard optimizer helps keep the system in good shape, preventing fragmentation of logical space and slowdown of interface response.
Run the built-in optimization once a week, preferably before rebooting the phone, so that the system applies changes most effectively.
Managing the cache of applications and system services
The most power-hungry element in a modern smartphone is the application cache. Messengers like Telegram or WhatsApp save every image and video viewed on disk so that the next time you open a chat, you don’t have to download them again from the network. Over time, this cache can reach tens of gigabytes, quietly eating up all the free space.
To clear the cache of a specific application, go to Settings → Applications. Select the desired app from the list and click on “Storage”. Here you will see two buttons: “Clear cache” and “Clear data”. The first deletes only temporary files, the second resets the application to its factory state, deleting logins and settings.
Particular attention should be paid to the browser Samsung Internet or Chrome. They store cached versions of web pages, cookies, and download history. Clearing this data will not only free up space, but may also solve problems with some sites not displaying correctly. In your browser settings, find the “Privacy” section and select “Delete browsing data.”
- 🧹 Social network cache: Instagram and TikTok save video previews and feeds, which can take up to 5 GB per month of active use.
- 🗺️ Offline maps: Google Maps and Yandex.Maps store downloaded map areas, which they often forget to delete after a trip.
- 🎵 Streaming cache: Spotify and YouTube Music cache tracks for offline listening, even if you do not have a premium subscription (to a limited extent).
The system cache also requires attention, but access to it is limited in new versions of Android. Previously, it was possible to clear the partition cache through Recovery Mode, but now this function is hidden or removed for security reasons. Instead, the system independently manages the system cache, deleting old files when there is not enough space.
Working with the gallery and cloud storage
Media files traditionally occupy the largest amount of memory on smartphones. Modern cameras Samsung record in high resolution, and the mode Expert RAW creates huge files. Often, users make hundreds of duplicates of the same frame or save screenshots that they never view.
The Gallery app has a built-in feature to find duplicates and similar images. The system offers to select the best frame from the series and delete the rest. It’s also worth checking the “Downloads” folder, where advertising images from browsers and attachments from mail often end up.
Integration with Google Photos or OneDrive allows you to free up local space by transferring files to the cloud. After successful synchronization, you can use the Free Up Space feature, which will delete copies already stored in the cloud from your device. This is a safe way to store archives without filling up the phone's internal memory.
| File type | Average size (MB) | Recommended action |
|---|---|---|
| Photo (JPEG) | 3 - 8 | Compress or delete duplicates |
| Video (4K 60fps) | 350 - 600 (per minute) | Transfer to PC/Cloud |
| RAW (DNG) | 25 - 50 | Process and delete source |
| Screenshots | 1 - 3 | Bulk deletion of old ones |
Don't forget about the "Trash" folder in the gallery. Deleted files do not disappear immediately, but are stored there for 30 days, continuing to take up space. To instantly free up memory, you need to go to the trash menu and select “Empty”. This action is irreversible, so make sure that you delete what is really unnecessary.
Before deleting the original photos after uploading to the cloud, check the compression quality in the cloud service settings so as not to lose the detail of the images.
Analysis of large files and download folders
Often space is taken up not by thousands of small files, but by a few forgotten ones archives or installation packages. The file manager My Files, which is preinstalled on all Samsung, has a convenient “Storage Analysis” tool. It shows files sorted by size, allowing you to quickly find the heavyweights.
Pay attention to the folder Download and messenger subfolders, such as WhatsApp/Media/WhatsApp Video. All received video files are automatically saved here, even those that you just scrolled through in the chat. Manually sorting this folder by date helps to identify and delete old content in a couple of minutes.
It is also worth checking for files with the extension .apk. These are application installation packages that remain in memory after the app is installed. They are no longer needed and can be safely removed. Searching by extension in the file manager will help you find them all at once.
⚠️ Attention: When deleting files from system application folders (Android/data), be extremely careful. Deleting the game cache may reset your progress if it is not saved in the cloud.
If you use your phone to work with documents, check the folder Documents. Often old versions of reports, presentations and tables accumulate there. Move current files to cloud storage, and delete local copies to save space.
Using maintenance mode and secure folder
A unique feature of the ecosystem Samsung is the “Secure Folder” function. This is an isolated space, protected by a password or biometrics, where you can store private photos, applications and files. Data inside this folder is encrypted separately and is not counted in the total space during standard browsing, but takes up real disk space.
If you rarely use Secure Folder, check its contents. There may be a cache of applications or old backups that can be deleted. To clear the space associated with this function, you need to go inside the folder and carry out the standard procedure for deleting files.
Maintenance Mode is a new feature designed primarily for sending the phone for repair. However, it is also useful for diagnosis. In this mode, the phone works with a minimal set of applications and a temporary user profile. This allows you to understand whether third-party apps are affecting the memory.
How to enter maintenance mode?
Go to Settings → Device maintenance → Maintenance mode. The phone will reboot into a special mode where your personal data will be hidden. A PIN code and a reboot will be required to exit.
Using these tools requires an understanding of the security structure One UI. The data in the Safe Folder is not visible when the phone is connected to the computer in normal mode, which often causes confusion among users looking for missing gigabytes.
Third-party utilities and advanced cleaning methods
When built-in tools are not enough, specialized applications come to the rescue. Files by Google is one of the most reliable utilities that can find memes, duplicates and unused applications. It works more softly than aggressive “cleaners” and does not delete system-important files.
For advanced users, it is possible to use ADB (Android Debug Bridge) via a computer. This allows you to remove system bloatware (pre-installed Samsung applications) that cannot be removed in the usual way. Commands like pm uninstall -k --user 0 require caution, but can free up a significant amount of the system partition.
adb shell pm list packages | grep samsung
adb shell pm uninstall -k --user 0 com.samsung.android.bixby.agent
However, using third-party “boosters” and “coolers” from the Play Market often does more harm than good. They themselves consume resources, show advertisements and create the illusion of cleaning by simply closing processes, which the system immediately starts again.
- 🛠 SD Maid: A professional tool for finding “corpses” of applications (residues after deletion).
- 📂 Total Commander: Allows you to manually manage the file system and find hidden folders.
- 🔍 DiskUsage: Visualizes memory in the form of a block map, showing what exactly is taking up space.
⚠️ Attention: Interfaces and menu names may vary slightly depending on the One UI version (4.0, 5.0, 6.0) and device model. If you do not find the specified item, use the search in the settings.
☑️ Complete cleaning checklist
Frequently asked questions (FAQ)
Why does the memory fill up by itself immediately after cleaning?
This is normal system behavior. Applications re-create the cache for faster operation, and the system writes logs. If the memory fills up critically quickly (in hours), it is possible that some application is not working correctly and is creating cyclic error logs. Try updating the problematic application or reinstalling it.
Is it possible to transfer applications to a microSD memory card on Samsung?
In modern versions of Android and the One UI shell, support for the Adoptable Storage function (when the card becomes part of the internal memory) is disabled by the manufacturer. You can transfer only some media files and documents to the card, but the applications themselves will only work from the internal memory to ensure speed and security.
Is it safe to delete the Android/data folder?
You cannot delete the entire folder - this will break the applications. However, you can go inside Android/data and delete the contents of specific application folders (for example, game cache) if you know what you are doing. It is better to do this through the settings of the application itself.
How to clear the memory if the phone freezes and does not allow you to enter the settings?
Try to boot into Safe Mode (hold the power off button on the screen, then press and hold the “Power off” icon on the screen until the prompt to boot into safe mode appears). In this mode, third-party applications are disabled, and you can remove the culprit of the problems.
Does clearing memory affect battery life?
Indirectly - yes. When the memory is full, it is more difficult for the memory controller to write new data (write slowdown effect), the processor works harder, which increases power consumption. Free 10-15% of memory ensures stable and energy-efficient operation of the storage controller.
