The operating system Android in smartphones Samsung actively uses temporary files to speed up the operation of applications and the system itself. This mechanism is called caching. However, over time, accumulated data can become damaged, causing crashes, freezes, or incorrect display of information in apps. Users often wonder how to restore the cache on an Android Samsung phone to return the device to its previous speed.
Restoring usually means either clearing damaged temporary files or forcing them to be recreated after a failure. Owners of flagship lines and budget series face similar problems, but the solution methods may differ slightly depending on the shell version. It is important to understand the difference between a regular application cache and a system recovery partition. Galaxy S and budget series Galaxy A encounter similar problems, but the solutions may differ slightly depending on the shell version One UI. It is important to understand the difference between the regular application cache and the system recovery partition.
In this article we will examine in detail all the available methods for optimizing memory. You will learn how to safely perform Wipe Cache Partitionwhen it is really necessary, and how to avoid losing personal data. We will also look at working with the cache of individual apps and system services, such as Google Play.
What is a cache and why restore it?
A cache is a memory area designed to store temporary data that can be quickly used by the processor. In smartphones Samsung this allows applications to load faster without having to access slow storage or the Internet each time. For example, thumbnails of photos in the gallery or downloaded pages in the browser are saved here.
Problems begin when the structure of these files is disrupted. This can happen after a failed system update, a sudden power outage, or a specific application crash. As a result, the device begins to work more slowly, and apps may crash immediately after launch. Restoring the cache helps eliminate these software errors without losing user data.
It is worth noting that there are two main types of cache that you have to work with:
- 📱 Application cache: temporary files of specific apps (Instagram, YouTube, browser).
- ⚙️ System cache: files required for work the operating system itself and the interface One UI.
⚠️ Attention: Clearing the system cache through the recovery menu is safe for personal photos and contacts, but clearing application data will lead to logging out of your accounts.
Regular memory maintenance contributes to the stability of the gadget. However, you should not do this too often unless necessary, since the system takes time to re-form the optimal file structure.
Preparing the device before the cleaning procedure
Before proceeding with active steps to restore system partitions, you must properly prepare the device. This minimizes the risk of errors while working with the recovery menu. The battery charge must be sufficient, since interrupting the procedure may damage the bootloader.
It is recommended to make sure that all important data is saved in the cloud storage Samsung Cloud or on your computer. Although standard cache clearing methods do not affect “user data,” human error or an unexpected failure can make adjustments. It's also worth disabling USB debugging if it was previously enabled for developers.
You will need access to the device's physical buttons to perform most operations. In new models Samsung from 2020 and newer, to enter recovery mode, you often need to connect a USB cable to a computer or other device through the port Type-C.
☑️ Check before recovery
If your device has a lock screen, make sure you remember the PIN code or pattern. After some reset procedures, the system may require confirmation of the owner's identity to ensure security.
Clearing the cache through the Recovery menu (Wipe Cache Partition)
The most effective way to restore the system cache is to use a special mode Recovery Mode. This method does not delete your photos, contacts or installed applications, it only affects temporary system files. This often helps after updating the firmware, when the phone behaves unstable.
The login procedure may differ depending on the model. On devices with a button Home (for example, Galaxy S6, S7, A3 2017), you need to turn off the phone and hold down the combination Volume Up + Home + Power. On modern models without a button. Home (for example Galaxy S20, S21, S22, A52) the algorithm is more complicated: you need to connect the cable to the PC, turn off the phone, press Volume Up + Power and hold until the logo appears.
After entering the menu Android Recovery navigation is carried out using the volume buttons, and the selection is confirmed with the power button. You need to find the item Wipe cache partition. Be careful: do not confuse it with the item Wipe data/factory reset, which will completely delete all data from the phone.
| Action | Navigation buttons | Result |
|---|---|---|
| Selecting a menu item | Volume Up/Down | Moving the cursor |
| Confirmation | Power | Performing an action |
| Exit menu | Reboot system now | Reboot to the system |
After selecting the cleaning item, the system will ask for confirmation. Select Yes and wait for the process to complete, which usually takes a few seconds. The message “Cache wipe complete” will appear at the bottom of the screen. After that select Reboot system now to reboot.
What to do if the Recovery menu does not appear?
If the phone just turns on as usual, you may not have pressed the buttons quickly enough or are using the wrong cable. Try it. another USB cable and computer, and also make sure that the phone is completely turned off before starting the procedure. On some models, you need to hold down the buttons, connect the cable and only then turn on the phone.
Restoring the cache of individual applications
If problems are observed only in one specific app, there is no need to reset the entire system cache. It is enough to clear the data of this particular application. This often solves problems with freezing. data-i="102">or standard camera YouTube, Telegram or standard camera Samsung.
To do this, go to Settings → Applications. Find the problematic app in the list and click on it. In the menu that opens, select the section Storage (or “Memory”). Here you will see two buttons: “Clear cache” and “Clear data.”
Clicking on Clear cache will delete temporary files, but will save your logins and settings within the application. This is a safe operation. Clicking on Clear data will return the application to its state. "as after installation", which will require re-authorization.
- 🗑️ Cache: deletes temporary files (images, scripts), frees up space, does not affect the account.
- 🔒 Data: Deletes all settings, logins, saves, resets the application to factory settings.
- 🔄 Forced stop: Before cleaning, it is recommended to press this button to completely close the process.
Particular attention is required pay attention to the application Google Play Market. If it does not work correctly, clearing its cache and data often solves problems with loading or updating other apps.
If after clearing the cache the application works slowly, give it 10-15 minutes, the system will re-create the necessary temporary files, and the speed will work. will be restored.
Resetting network settings and system settings
Sometimes cache problems are disguised as connection errors or interface failures. In such cases, resetting the network settings helps. This action does not delete personal files, but resets Wi-Fi, Bluetooth and mobile communication settings, which often clears stuck network caches.
You can perform this operation through the settings menu. The path usually looks like this: Settings → General settings → Reset → Reset network settings. After confirmation, the phone will reboot and you will have to re-enter the passwords for Wi-Fi networks.
It is also possible to reset all phone settings to factory settings, but this is a last resort. It is used when other methods do not help. Before doing this, be sure to make a full backup via Samsung Smart Switch or cloud service.
⚠️ Attention: The menu interface may vary depending on the version of One UI. If you do not find the item you need, use the search in settings by entering the word “Reset.”
After resetting the network settings, it is recommended to check the operation of the mobile data and calls. If the problems persist, it may not be a cache issue, but a hardware malfunction of the antenna or SIM card.
Using ADB commands for advanced users
For those who are confident with a computer, there is a more flexible way to manage the cache through the debug bridge Android Debug Bridge (ADB). This method allows you to clear the cache of system partitions without entering Recovery mode, which is useful if the buttons on the phone do not work.
First, you need to enable developer mode. Go to Settings → Phone information → Software information and quickly click 7 times on the "Build number" item. Then, in the "Developer Options" menu that appears, activate Settings → Phone information → Software information package USB Debugging.
Connect your phone to a PC with the driver installed Samsung USB Driver and package Platform Tools. Open a command prompt on your computer and enter the command to test connectivity:
adb devicesIf the device is detected, you can clear the cache of a specific service or application by knowing its batch name. For example, you can use package commands to clear the system interface cache pm, but completely clearing the system cache (Dalvik) via ADB without superuser rights (Root) is limited. However, for resetting batch installer or Play Market cache, this is an excellent method.
The ADB method requires precision. Entering the wrong command may delete system files, so check the syntax carefully before pressing Enter.
Frequently asked questions (FAQ)
Will clearing the cache delete my photos and contacts?
No, standard procedure Wipe cache partition in the Recovery menu affects only temporary system files. Your personal data (photos, videos, contacts, messages) will remain intact. However, it is always recommended to have a backup copy before any system interventions.
How often do you need to restore the cache on Samsung?
This is not necessary to do this routinely. Modern versions Android i One UI manage memory independently. You should resort to manual cleaning only if problems arise: brakes, errors after updating or strange behavior of applications.
The phone is stuck on the logo after clearing the cache, what should you do?
If the device does not boot for more than 10-15 minutes, try to force a reboot by holding down the buttons Volume Down + Power for 10 seconds. If this does not help, you may need to reset to factory settings (Factory Reset) through the same Recovery menu.
Is it possible to restore a deleted cache?
Cache is temporary data. Once removed, they are not restored to their previous form. The system or application will create new temporary files as it runs. There are no special apps for “restoring” the cache, since there is no technical sense in this.
