Owners of smartphones from the South Korean brand often experience slowdowns in the device after several months of active use. The system Android accumulates temporary files that are designed to speed up the launch of applications, but over time their excess leads to the opposite effect. Users begin to notice “brakes”, interface freezes and rapid battery drain.
However, do not immediately panic or look for a service center. Clearing the cache is a standard maintenance procedure that can be performed by any user. In this article, we will look at various ways to access hidden sections of memory, look at safe methods for deleting temporary data, and answer popular questions about how this affects operation Samsung Galaxy.
Understanding where this data is stored and how to manage it is the key to the long life of your gadget. We will not use third-party cleaning apps, since the built-in tools One UI provide all the necessary capabilities for deep cleaning.
What is the cache and why it needs to be cleaned on Samsung
The cache is an area of RAM or permanent memory where temporary files are stored. When you open an application, for example, a browser or a social network, the system saves some of the data (images, scripts) in cache memory. This is done so that the next time you launch the application, it opens instantly, without downloading content again from the Internet.
However, over time, these files can become damaged or take up a critical amount of space. This is especially true for multimedia applications, such as TikTok, Telegram or Instagramthat accumulate gigabytes of garbage. The accumulation of corrupted cache files is one of the common reasons why applications suddenly close on Samsung.
Regular cleaning helps free up space and eliminate software conflicts. It is important to understand the difference between user data and the cache: deleting the cache will not affect your logins, passwords or correspondence, unlike completely clearing the data.
⚠️ Attention: Do not confuse clearing the application cache with formatting the internal memory. Deleting the cache is safe, but resetting all data will return the phone to factory settings.
The system Android on devices Samsung automatically manages these processes, but manual control is sometimes necessary. If you notice that a particular application is not working correctly, the first thing you should do is clear its cache.
Clearing the cache of a specific application through settings
The safest and most common way to manage memory is to work with the settings of each application separately. This method allows you to specifically delete temporary files of a app that causes suspicion of incorrect operation or takes up too much space.
First, you need to go to the main settings menu. Find the item Applications in the list of main options. This displays a complete list of all installed apps, including system processes One UI.
Select the desired application from the list. If you're looking for a specific app, you can use the search bar at the top of the screen or sort applications by memory size, which is often more convenient.
Inside the application menu, find the section Memory or Storage. Here you will see two buttons: “Clear cache” and “Clear data”. We are interested in the first option. Clicking on it will instantly delete temporary files without losing your personal settings inside this application.
☑️ Checking the application before cleaning
It is worth noting that after clearing the cache, the application may take a little longer to start than usual when first started. This is normal behavior, since the system Android needs to regenerate temporary files.
Using the “Device Maintenance” section for quick cleaning
The company Samsung has implemented a powerful built-in tool into the shell One UI optimization. It allows you to quickly clear the cache of all applications at once, without going through each one manually. This is especially useful when you urgently need to free up space or speed up your phone before starting a heavy game.
To use this function, open Settings and find the item Device Maintenance (or “Device Care”). In some firmware versions, this section may be simply called “Optimization.”
In the menu that opens, select section Memory. The system will perform a quick analysis and show how much space can be freed up. Click the button Clear now. This process will only take a few seconds.
| Action | What is being deleted | Risk of data loss |
|---|---|---|
| Clear cache | Temporary files, thumbnails | No |
| Cleaning data | Logins, settings, databases | High |
| Deleting applications | The app and all its files | Full |
This method is most recommended for ordinary users, as it eliminates the risk of accidentally deleting important information. Algorithms Samsung determine which files are safe to delete.
Use the Device Optimization widget on the home screen for quick access to clearing memory without entering deep settings menus.
Deleting the system cache through the Recovery menu
There is a deeper level of cleaning that affects the system cache itself Android. This method is often used after a firmware update, when the phone becomes unstable, heats up, or discharges quickly. The Wipe Cache Partition does not affect the user's personal files.
To enter Recovery Mode on modern smartphones Samsung you often need to connect to a computer via a USB cable. This is a new security requirement introduced in the latest versions. One UI.
Turn off your smartphone completely. Connect it with a USB cable to a running computer or laptop. Then hold down the volume up button (Volume Up) and the power button (Power) at the same time. Hold them until the logo appears Samsungthen release the Power button, but continue to hold the volume.
When a black menu appears with the text (Recovery Mode), use the volume buttons to navigate up and down. Find the item Wipe cache partition. Confirm your selection by briefly pressing the Power button. A confirmation request will appear on the screen, select Yes.
⚠️ Attention: The touch screen does not work in the Recovery menu. Control is carried out only by physical volume and power buttons. Be careful not to select Wipe Data, which will delete everything from the phone.
After the process is completed, which takes a few seconds, select Reboot system now to reboot. The phone will take longer to turn on than usual - this is normal for the first boot after clearing the system cache.
What to do if the Recovery menu does not open?
If the button combination does not work, try connecting the phone to a wall charger instead of the computer. On some models, this will also activate the debug mode required to log in.
Clearing the DNS and browser cache to speed up the Internet
Often, problems with page loading speed are not related to the total amount of memory, but to a full DNS cache or the browser itself. This is relevant if sites take a long time to open or are displayed incorrectly.
You can use the hidden menu to clear DNS on Android . Open the “Phone” application (dialer) and enter the code *#72786# (the code may vary depending on the operator and model, but often works on Samsung). However, a more universal way is through the developer settings or resetting network settings.
An easier way is to clear the browser cache. Go to Settings → Applications, find your browser (Chrome, Samsung Internet). Go to Memory and click Clear cache. This will delete temporary web page files.
It is also worth checking your private DNS settings. Go to Settings → Connections → Other connection settings → Personal DNS. If the address is registered there, try switching to “Auto” or using a reliable service, for example dns.google.
Regularly clearing the browser cache not only helps speed up your work, but also increases privacy by removing traces of visited sites stored in temporary files.
Automation of cleaning with Using Bixby Routines
Smartphone owners Samsung have a unique advantage - a built-in automation tool Bixby Routines (or “Modes and Scenarios”). It allows you to set up automatic cache clearing on a schedule or when certain conditions are met.
Open the application Modes and scenarios. Go to the Automation tab and click Add. For the condition (“If”), select “Charging” or “Time.” For example, you can set it to clean every night while charging.
As an action (“To”), select “Device care” → “Memory cleaning”. Save the script. Now your phone will independently keep the system clean without your intervention.
This is an ideal option for those who forget about manual maintenance. Automation ensures that the cache does not grow to critical sizes that affect performance.
Using Bixby Routines turns the routine task of clearing memory into an automatic background process, saving you time and device resources.
Frequently asked questions (FAQ)
Will it delete my WhatsApp correspondence after clearing the cache?
No, clearing the cache (Clear Cache) deletes only temporary files necessary for the application to function. Your messages, photos and contacts will remain intact. The correspondence will be deleted only if you click “Clear data” (Clear Data).
How often do you need to clear the cache on Samsung?
There is no special frequency. It is enough to do this once every 1-2 months or when you notice a lack of memory. System optimization One UI itself monitors the state of the memory, therefore daily cleaning is not required.
Is it true that clearing the cache speeds up the phone?
Yes, if the cache is full or contains errors. Freeing up space on the system partition allows the processor to access needed files faster. However, if the phone is old, you should not expect a miraculous increase in speed - this does not replace the purchase of a new device.
Is it possible to restore a deleted cache?
No, cache files are created anew by applications during their use. It is neither necessary nor possible to restore them manually, since this is temporary information. The applications themselves will create a new cache the next time they start.
