Over time, the operating system Android inevitably slows down. This occurs due to the accumulation of application cache, residual files of uninstalled apps and fragmentation of internal memory. For users facing a critical decrease in performance or planning to sell the device, the issue of complete cleaning becomes paramount.
In this article we will analyze in detail all the available methods of how to clean Android 10 completely, returning the smartphone to factory speed and cleanliness. We will consider both the software of the system itself and radical methods of resuscitation through the recovery menu.
Before taking active steps, you need to realize that any form of a hard reset will lead to irretrievable loss of user data. Photos, contacts and correspondence will disappear if you do not take care of saving them in cloud storage or on your computer in advance.
Preparing the device for global cleaning
The procedure for completely deleting data requires careful preparation, since it will be impossible to cancel it after launch. The first step should always be to synchronize important information with your account Google or create a local backup.
Many users forget to unlink their accounts before resetting, which leads to the protection FRP (Factory Reset Protection) being triggered. This is a security system that requires you to enter the password from the last synchronized account after turning on the phone.
⚠️ Attention: If you do not remember the password for your Google account, be sure to restore it before resetting, otherwise the phone will turn into a “brick”, access to which will be extremely difficult.
It is also critical to check the battery level. The process of formatting the data partition can take from 10 to 30 minutes depending on the amount of memory and speed of the drive.
☑️ Checklist before resetting
Do not ignore removing the memory card microSD. Although modern versions of the system often offer a choice of whether to format an external card, human error or a software failure can lead to the destruction of the external media along with the internal memory.
Standard reset through system settings
The safest and recommended way to clear Android 10 is to use the built-in settings menu. This method correctly closes all active processes and formats without the risk of damaging system partitions.
The interface may differ slightly depending on the manufacturer's shell (MIUI, One UI, ColorOS), but the logic of the path remains the same. You need to find the section responsible for managing the system or general reset.
The action algorithm is as follows:
- 📱 Open the "Settings" application on the main screen.
- 🔄 Go to the section
SystemorGeneral settings. - 🗑️ Select item
ResetorRestore and reset. - 💣 Click on the option
Delete all data (reset to factory settings).
The system will ask you to confirm the action, you may need to enter a pattern or screen lock PIN. Once confirmed, the device will reboot and begin the cleaning process.
If the phone asks for your Google Account password at the end of the reset process through Settings, this is normal operation of the anti-theft feature. Enter the data from the mail you used on the device.
It is important to note that this method only deletes user data from the section /data. System applications and operating system updates are saved, which allows you to immediately start using the phone after booting.
Hard Reset via the Recovery menu
If the device freezes, does not boot, or you have forgotten the unlock password, the standard method becomes unavailable. In such cases, the recovery mode comes to the rescue, known as Recovery Mode.
This menu is entered using hardware buttons before loading the manufacturer's logo. Key combinations vary: most often it is holding the volume up button together with the power button.
⚠️ Attention: In the Recovery menu, the touch screen does not work. Navigation is carried out using the volume buttons (up/down), and the selection is confirmed with the power button.
After entering the menu, you will see a list of technical options. You need to find the item Wipe data/factory reset. Using the volume buttons will allow you to move the cursor, and the power button will select items.
| Action | Navigation button | Confirmation button | Result |
|---|---|---|---|
| Move up | Volume + | - | Cursor goes up |
| Move down | Volume - | - | Cursor goes down |
| Select item | - | Power | Activate function |
| Reset confirmation | Volume - | Power | Start formatting |
After selecting a reset point, the system usually requires additional confirmation to avoid accidental activation. Select Yes or Factory data reset in the menu that appears.
What to do if the Recovery menu does not appear?
If the button combination does not work, try connecting the phone to the computer via a USB cable and then hold down the buttons. Some models require you to enable USB debugging mode first, but this is not possible when your phone is locked. In such cases, all that remains is to wait for the battery to drain or use specialized software on the PC.
When the process is completed, the message about successful wipe will appear on the screen. Select Reboot system nowto restart the device in normal mode. The first boot after a Hard Reset may take longer than usual.
Removing viruses and malware
Often users are looking for a way to clean Android 10 completely, suspecting the presence of viruses that are not removed by standard antiviruses. Complete data wipe is the most effective method of combating deeply embedded malicious code.
However, before a radical reset, you should try less aggressive methods. Sometimes it is enough to remove the problematic application in safe mode, where third-party software does not start automatically.
To enter safe mode, hold down the power button on the screen, and then press and hold the “Shut down” icon on the display until you are prompted to switch to safe mode. Confirm the action.
- 🛡️ In safe mode, remove recently installed suspicious applications.
- 🧹 Clear the browser cache and folder
Downloadfrom unknownAPKfiles. - 🔄 Reboot the device in normal mode and check the operation.
If the symptoms of infection persist, only a full reset via Recovery guarantees the removal of malware that could gain superuser rights or infiltrate system processes.
After returning the phone to factory settings, it is strongly recommended not to Restore backup applications immediately. Install only the necessary software from the official store Google Play.
Cleaning internal memory without losing data
Total deletion of information is not always required. If your goal is to make room for new files, not to sell your phone, use the built-in optimization tools. This will save personal data.
The Android 10 implemented the “Smart Storage” function, which automatically finds and suggests deleting duplicates, old screenshots and unused applications. Access to it is in the storage settings.
Also an effective method is to manually clear the cache of heavy applications, such as social networks and instant messengers. These apps can take up several gigabytes of temporary files.
Go to Settings → Applications, select the desired app (for example, Telegram or YouTube) and press Storage. There you will see a “Clear cache” button. Do not confuse this with the “Erase Data” button, which will delete all application information.
⚠️ Attention: The “Erase Data” function inside a specific application will delete your correspondence and login settings in that application, even if you did not completely reset the phone.
Regular use of these tools allows you to keep your system clean for months without having to resort to extreme measures of full formatting.
Cleaning application cache is safe for your personal data, unlike the “Erase data” function, which deletes settings and history within a specific app.
