Modern smartphones Samsung have powerful hardware, but over time, even flagship models begin to work slower due to the accumulation of digital garbage. This is a natural process of exploitation in which applications create temporary files, cache data, and leave traces of uninstalled apps. Understanding how to clean the system on a Samsung Androidis a key skill for maintaining high performance of the device throughout its entire service life.
Users often encounter a low memory notification when the storage is 90% full or more. At this point, the operating system begins to experience difficulties with writing new data and swapping processes. Regular maintenance, including deleting unnecessary files and optimizing settings, allows you to avoid a critical drop in interface speed and application freezes.
In this article we will look at not only the company’s standard tools, but also advanced methods available through the engineering menu and third-party utilities. You will learn which folders can be deleted without fear of losing personal data, and which ones are strictly prohibited from being touched. An integrated approach to the issue will provide your gadget with a second youth without the need to visit a service center.
Use of the built-in Samsung optimizer
The company Samsung has introduced into the shell One UI a powerful system tool that automatically analyzes the state of the device. This mechanism scans RAM, data storage and battery status, suggesting simple actions to the user to improve the situation. It is accessed through the settings menu or a widget on the main screen.
To start the process, you need to go to the section Settings → Device maintenance. Here you will see a pie chart showing the current system status. Clicking the button Optimize now runs an automatic script that closes background applications, deletes temporary files and checks the security of the device. This is a basic level of maintenance that is recommended to be performed daily.
However, the automatic mode does not always remove everything unnecessary, especially large files that the system considers potentially important. In the section Memory inside the maintenance menu, you can manually select categories of files to delete. The system will offer to clear application cache, advertising identifiers and unused files. This approach allows you to free up from 500 MB to several gigabytes of space in one session.
⚠️ Attention: When using the “Clear All” function in the memory section, carefully check the list of files. Sometimes the system marks downloaded documents or photos as garbage that you have not yet had time to view.
Set up automatic optimization in the "Auto-optimization" menu so that the phone cleans itself at night when you do not use it.
Manually clearing the application and data cache
The largest amount of garbage is usually accumulates in the cache of social networks, instant messengers and browsers. Applications like Telegram, WhatsApp or YouTube can take up several gigabytes of space, saving watched videos and images for quick access. Manually clearing this data requires a more targeted approach than using a general optimizer.
To clear the cache of a specific application, go to Settings → Applications. Select a app from the list that consumes a lot of resources. Inside the application card, find the item Memory or Storage. You will see two buttons: "Clear cache" and "Clear data". The first deletes temporary files, the second resets the application to factory settings, deleting logins and correspondence.
Particular attention should be paid to the browser Chrome or Samsung Internet. Over the years of use, they accumulate gigabytes of cached pages and cookies. Clearing your browser history and cache not only frees up space, but also improves your privacy by removing traces of your online browsing. This is especially true before selling the device or transferring it to another person.
- 🗑️ Application cache - safe to delete, does not delete your accounts.
- 🔒 Application data - deletes logins, settings and local game saves.
- 📂 Media cache - files downloaded from chats, but not saved to the gallery.
There is a nuance when working with instant messengers. Internal settings Telegram allow you to control the cache size more flexibly than the system menu Android. You can set a limit, for example, 1 GB, and the messenger itself will delete old files as they fill up. This prevents the memory from suddenly filling up at the time of an important call or update.
☑️ Check before clearing data
Storage analysis and removal of duplicates
Often the problem of lack of space is associated not with system garbage, but with the user’s personal files. Duplicate photos, forgotten downloads and old videos take up the lion's share of space. The built-in storage analyzer in smartphones Samsung helps you visualize what exactly is taking up space on your disk.
Go to the application My files and select Storage analysis. The system will show a graph of data distribution by category: images, videos, audio, documents and applications. By clicking on any category, you will see a list of the largest files. This allows you to quickly find a forgotten movie in 4K resolution or a series of photographs taken six months ago.
The folder Download (Downloads) deserves special attention. All files from the Internet, attachments from mail and documents from work chats are automatically saved here. Many users do not look here for years, allowing the folder to grow to tens of gigabytes. Regular audit of this directory is the easiest way to quickly free up space.
| File type | Average size | Recommendation | Deletion security |
|---|---|---|---|
| Application cache | 100 MB - 2 GB | Clean regularly | High |
| Downloads | Unlimited | Check manually | Medium |
| File .thumbnails | Up to 1 GB | Delete when gallery freezes | High |
| Logs system | 50-200 MB | For developers only | Low |
What is the .thumbnails folder?
This is a hidden system folder where thumbnails of your photos for quick display in the gallery. Over time, it can grow to enormous sizes if you have a lot of photos. Deleting it is safe - the system will re-create it, but the first launch of the gallery may be slow.
Working with a memory card and transferring files
If your smartphone Samsung supports the installation of memory cards microSD, this is a great way to relieve internal storage. Transferring media content to external media frees up space for operating the operating system and installing new applications. However, it is important to understand the difference between file transfer and memory pooling.
In modern versions Android the Adoptable Storage function is often hidden or missing. Therefore, the most reliable method is to manually move folders. Through the file manager My files you can move folders DCIM (photos and videos), Music and Documents to a memory card. Applications will remain in the internal memory, which will ensure their fast operation.
It is worth noting that the speed of the memory card is usually lower than the speed of the internal flash drive. Therefore, it is not recommended to transfer active applications or games to it that require fast loading of textures. This can lead to slowdown of the interface and long loading times for levels. The memory card is ideal for archival storage of content.
⚠️ Attention: Formatting the memory card as internal memory will encrypt it, and you will not be able to read data from it on other devices or a computer without special access.
Cleaning through Recovery Mode
For deep cleaning of the system, when the smartphone is unstable or very slow, you can use the recovery mode. This method allows you to clear the partition Cache Partition, which is not available from the regular settings menu. System temporary files for updates and OS operation are stored here.
Entering recovery mode on new models Samsung requires connecting a USB cable to the computer. First, turn off your phone completely. Then press the combination of buttons Volume Up and Powerholding them until the logo appears. On older models, a connection to a PC is not required. In the recovery menu, control is carried out using the volume buttons, and selection is made using the power button.
Select item Wipe Cache Partition. Confirm the action by selecting Yes. The process will take a few seconds. It is important not to confuse this item with Wipe Data/Factory Reset, which will completely delete all your personal data and reset the phone to factory settings. Clearing the cache partition is safe for user files.
The procedure in Recovery:1. Turn off the device.
2. Connect the USB cable to the PC.
3. Press Volume Up + Power.
4. Select "Wipe Cache Partition".
5. Confirm and reboot (“Reboot system now”).
Cleaning the Cache Partition via Recovery does not delete your photos, contacts or applications, it only removes system temporary garbage.
Third-party utilities and cloud services
Although the built-in tools are usually sufficient, sometimes more specialized tools are required. Applications like Files by Google or SD Maid offer advanced algorithms for searching for duplicates, broken links and residual files after uninstalling apps. They can find what a standard analyzer misses Samsung.
The use of cloud storage, such as Google Photos or OneDriveintegrated into the ecosystem Samsungallows for a “store in the cloud, delete locally” strategy. The "Free up space" feature in Google Photos finds photos that are already uploaded to the cloud and deletes them from the phone's memory, leaving them available for viewing via the Internet.
When installing third-party cleaners, avoid aggressive applications that promise to "speed up RAM" by constantly closing background processes. Modern Android manages RAM very well, and forcibly closing services only increases battery consumption, since the system has to constantly restart them. Trust only trusted developers.
- ☁️ Google Photos - automatic upload and deletion of local copies.
- 🧹 SD Maid - search for "corpses" of deleted applications and system garbage.
- 📁 Files by Google - smart detection of duplicates and large files.
⚠️ Warning: Avoid applications with names like "RAM Booster" or "Battery Saver" that require superuser rights. They often contain advertising and can interfere with system stability.
Frequently asked questions (FAQ)
Is it safe to delete the Android folder on a memory card?
No, deleting the entire folder Android is not recommended. It stores application data, caches and game settings. Deleting will reset progress in games and loss of app settings. You can only delete subfolders of specific deleted applications if you are sure of their purpose.
Why does the space quickly run out again after clearing the memory?
Most likely, you have the automatic download function active in instant messengers (WhatsApp, Telegram). Check the settings of these applications and disable auto-downloading of media on mobile networks. It is also possible that the system creates new error logs if some application does not work correctly.
Is it possible to remove Samsung system applications through settings?
Most system applications cannot be deleted in the standard way, only the “Disable” option is available. This hides the application and prevents it from running, freeing up some RAM but leaving storage space occupied. Complete removal requires root access or using ADB through a computer.
How often do you need to clear the cache on Samsung?
It is enough to carry out preventive cleaning once every 1-2 months or when you receive a notification about a lack of space. Daily cleaning does not make sense, since the cache speeds up the operation of applications, and the system will have to create it again, using up processor and battery resources.
Does filling the memory affect Internet speed?
Indirectly, yes. If memory is critically full (less than 500 MB remaining), the system cannot effectively cache browser data and buffer streaming video. This can lead to slowdowns when loading pages and buffering of video content, although the connection speed from the provider does not change.
