Series smartphones Samsung Galaxy are distinguished by high performance and optimization, but over time even the most powerful devices can slow down. The reason for this is often the accumulation of temporary files and residual data that are saved by applications to speed up their work. This mechanism is useful in the short term, but if it accumulates in excess, it begins to consume precious space in the internal memory and cause crashes.
Many users mistakenly believe that to clean the system it is necessary to remove the apps themselves or perform a full reset. In fact, there is a more gentle and effective method - mass cache clearing. This procedure is safe for your personal data and allows you to return your phone to its former speed without losing contacts, photos or installed games.
In this article we will analyze in detail all the available methods for deleting temporary files on devices with shell One UI. You will learn how to use the system's built-in tools, hidden engineering menus, and third-party software for deep cleaning. We will also touch on the nuances of working with different versions Android, since the path to the settings may differ slightly depending on the year of manufacture of your Galaxy S or Galaxy A.
Why the cache accumulates and how it affects the operation of Samsung
The cache is an area for storing temporary data that applications use for quick access to frequently used information. For example, the browser saves images of websites, and social networks save thumbnails of photos, so as not to download them from the Internet each time. This saves traffic and speeds up opening pages.
However, over time, the size of this folder can reach several gigabytes. When there is little free space left on the disk, the system begins to work slower. File system experiences difficulties with indexing, and the processes of writing and reading data slow down. This is especially noticeable on models with a small amount of built-in memory, for example, 64 GB or 128 GB.
In addition, damaged cache files can cause apps to not work correctly. You may experience sudden application crashes, interface freezing, or elements not displaying correctly. Regular cleaning helps eliminate these software conflicts and restore the stability of the operating system.
⚠️ Attention: Clearing the cache does not delete your logins, passwords, correspondence or game saves. However, after the procedure, applications will take some time to re-load the data, so the first time they launch they may work a little slower than usual.
The standard cleaning method is through the device maintenance menu
The company Samsung has introduced a convenient system optimization tool into its smartphones, which is located in the settings. This is the safest and recommended method for most users as it eliminates the risk of deleting important system files. The interface is intuitive and accessible even to beginners.
First, you need to go to the main settings menu of your device. Find the section, which in different firmware versions may be called Device maintenance or Device care and battery. Typically, this icon is located at the top of the settings list and has a characteristic icon in the form of a battery or a gear.
Inside this section, the system will automatically analyze the memory status and offer to optimize the phone's operation. Click on the item Memoryto see detailed statistics on storage usage. Here you will see a button Clean up nowthat will start the process of deleting temporary files and unnecessary leftovers.
Before pressing the cleanup button, pay attention to the amount of freed up space. If the system shows less than 100 MB, it may be worth manually checking individual heavy applications such as YouTube or Telegram.
After the process is completed, the system will show a notification about successful optimization. It is recommended to restart your smartphone for the changes to take effect completely. This method clears not only the application cache, but also the system cache, as well as advertising identifier files.
The built-in One UI tool cleans system junk safely, but may miss the cache of some third-party instant messengers that store data in protected directories.
Manually clearing the cache for each application separately
Sometimes automatic cleaning does not give the desired result, since some applications store huge amounts of data in their private folders. In such cases, a manual approach is required to control what exactly is deleted. This is especially true for social networks and video players.
Go to the section Settings and select item Applications. You will see a complete list of all installed apps. For convenience, you can sort them by size by clicking on the filter icon or three dots in the corner of the screen and selecting the appropriate sorting option.
Select the application that takes up the most space. Inside the app card, find the section Storage. Here you will see two main buttons: Clear cache and Clear data. It is important not to confuse them: the first deletes only temporary files, the second resets the application to the “as after installation” state.
| Clearing type | What deleted | Security | Recommendation |
|---|---|---|---|
| Clear cache | Temporary files, thumbnails, logs | Absolutely safe | Can be done regularly |
| Clear data | Settings, logins, databases | Requires re-login | Only in case of failures |
| Delete updates | Application version is being rolled back | Safe, but inconvenient | For critical errors |
| Forced stop | Current processes in memory | Safe | Before cleaning cache |
Repeat this procedure for all resource-intensive applications. Although it takes longer than automatic cleaning, you get full control over the process and are guaranteed to free up space in the heaviest apps.
☑️ Check before manual cleaning
Using secure boot mode for deep cleaning
If standard methods do not help or the phone works extremely unstable, you can use safe boot mode. In this mode, only system applications are launched, which allows you to remove the cache of background processes that are usually blocked by active user work.
To enter this mode, hold down the power button on the screen until the power menu appears. Then press and hold your finger on the icon Turn off on the screen until you are prompted to enter safe mode. Confirm the action and the phone will reboot.
In Safe Mode, you can follow the path Settings → Applications and clear the cache of system services that are usually not available for modification. This includes the cache of the interface One UI Home, system launcher and services Google Play.
⚠️ Attention: In safe mode, some phone functions will not be available, and a corresponding message may be displayed in the corners of the screen. To exit the mode, simply reboot your device as usual.
This method is especially effective if you suspect that some third-party application is interfering with normal cleaning or consuming resources in the background. After cleaning, be sure to perform a full reboot to exit the special mode.
How to understand that the problem is in a third-party application?
If in safe mode the phone works quickly and the cache is cleared without errors, then the problem is caused by one of the applications you installed. Try deleting them one by one to find the culprit.
Cleaning through the engineering menu and Recovery Mode
For advanced users, it is possible to clear the system cache partition through the recovery menu Recovery Mode. This method deletes temporary files at the system-wide level, rather than individual applications. It is useful when updating firmware or serious malfunctions Android.
To enter this menu, you must turn off your smartphone. Then, depending on the model, you need to hold down a combination of buttons. On new models Samsung without a physical "Home" button, you need to connect the phone with a cable to the computer and hold down the Volume up and Power buttons at the same time.
In the menu that appears, navigation is carried out using the volume buttons, and selection is made using the power button. Find the item Wipe cache partition and confirm your choice. The system will warn you about the actions, after which it will begin the cleaning process, which will take a few seconds.
Recovery Menu Navigation:Volume Up/Down - Move cursor
Power Button - Select option
Wipe cache partition - Confirm action
After completing the procedure, select the item Reboot system now. The phone will reboot normally. This method does not affect your personal files, but requires care not to select the option to reset all data (Wipe data/factory reset).
Using Recovery Mode is the most radical method of clearing the system cache, which is recommended only if there are obvious problems with the operation of the operating system.
Third-party applications to automate the process
If you do not want to manually go through the settings each application, you can use specialized software from the store Google Play. There are many utilities that promise to speed up the phone in one click, but their choice should be approached with caution.
Applications from well-known developers such as CCleaner or Files by Googleare considered the most reliable. transparent operating algorithm and do not impose unnecessary advertising. Such apps scan the system and offer to delete only those files that are definitely garbage.
- 🚀 Files by Google - an official application from the search giant that safely cleans duplicates and temporary files.
- 🧹 CCleaner - a powerful tool with real-time system monitoring and automatic cleaning.
- 🛡️ SD Maid —an advanced solution for experienced users that allows you to find the “corpses” of deleted applications.
- ⚡ 1Tap Cleaner —a utility designed specifically to quickly clear the cache of all applications in one click.
When using third-party apps, it is important to grant them the necessary permissions. Usually, access to storage and usage statistics is required. Without these rights, the application will not be able to see the cache size of other apps and. clear it.
⚠️ Attention: Avoid installing “boosters” from unknown developers that promise to increase RAM significantly. Often such apps themselves are a source of advertising and slow down the device.
Why doesn’t Android clear the cache itself?
Modern versions of Android are designed so that free memory space is used. for caching to speed up work. The system itself deletes old files when space runs out, but sometimes this mechanism fails.
Frequently asked questions (FAQ)
Will my WhatsApp correspondence be deleted when clearing the cache?
No, clearing the cache does not affect message databases, media files and account settings. Your chats will remain completely intact. Only temporary files are deleted, for example, image thumbnails, which will be reloaded when you open the chat.
How often do you need to completely clear the cache on Samsung?
The optimal frequency is once every 1-2 months. If you actively use social networks and video services, you can do this more often. Daily cleaning does not make sense and may even slow down the phone, since applications will have to constantly re-create temporary files.
Why does the application cache grow quickly again after cleaning?
This is normal behavior. Applications create a cache for their fast operation. If the cache grows abnormally quickly (gigabytes per day), this may indicate an error in the application code or incorrect loading of content. In this case, you should try updating or reinstalling the app.
Is it possible to clear the cache of all applications with one command without root access?
It is impossible to clear the cache of absolutely all applications with one button using standard Android tools without root access for security reasons, however, the built-in “Device Maintenance” tool does this as close to ideal as possible, clearing most system and user temporary ones. files.
Does clearing the cache affect battery life?
Indirectly, yes. When memory is low, the phone's processor works harder trying to manage files, which consumes more energy. Freeing up space and deleting bad cache files can reduce the load on the processor and extend battery life a little.
