Formatting an Android device is a radical, but sometimes necessary step to solve system problems, remove viruses or prepare gadget for sale. Unlike simply clearing the cache, a full reset deletes all user datareturns the smartphone to its out-of-the-box state. However, many users are afraid of this procedure because of the risk of losing important files or disrupting the system.
In fact, with the right approach, formatting Samsung Galaxy, Xiaomi Redmi or any other Android device takes no more than 10-15 minutes and does not require special skills. The main thing is to understand the difference between soft reset (through settings) and hard formatting (through recovery mode), and also know how to save critical data before the process. In this article we will analyze all the current methods, including hidden functions for experienced users.
Preparing for formatting: what you need to do before resetting
Before you start resetting, make sure what are you saved all important data. Formatting deletes:
- ๐ธ Photos and videos (including hidden folders)
- ๐ฑ Contacts, SMS and call log (if not synchronized with Google)
- ๐ฎ Game saves and settings applications
- ๐ Downloaded files and documents
- ๐ Wi-Fi passwords and application accounts
For backup, use:
- ๐ฅ๏ธ Google Drive (automatic synchronization of contacts, photos and some settings)
- ๐ฑ Built-in manufacturer tools (for example, Samsung Smart Switch or Xiaomi Cloud)
- ๐พ Manual copying to a PC via
MTP-protocol (USB connection) - ๐ Specialized applications like Titanium Backup (requires root access)

Method 1: Soft reset via Android settings
The simplest and safest method is resetting direktno from the settings menu. It is suitable if:
- ๐ฑ The phone turns on and responds to touches
- ๐ Do you remember the pattern key or PIN code
- ๐ซ No serious system failures (freezes, reboot cycles)
Instructions:
- Open
Settings(gear in the menu applications). - Go to section
System โ Reset settings(on some devices the path may differ:General settings โ Reset). - Select
Delete all data (factory reset). - Enter the PIN code or pattern to confirm.
- Click
Reset the phoneand wait for completion (usually 5-10 minutes).
After the reboot, you will be asked to set up the device as new. If a request appears on the screen to enter the details of the Google account that was linked before the reset, this means that FRP protection (Factory Reset Protection) has worked. To bypass it, you will need to enter the login and password for this account.
What to do if I donโt remember the password for your Google account?
If you have forgotten your account details, restore access via [Google recovery link](https://accounts.google.com). If your account is deleted or inaccessible, the only way to unlock your phone is to contact a service center with proof of ownership of the device. (receipt, box).
Method 2: Hard formatting via Recovery Mode
If the phone does not turn on, is stuck on the logo or does not respond to touches, you will have to use recovery mode. (Recovery)This method is also useful if:
- ๐ Forgotten pattern key or PIN code
- ๐ฆ The device is infected with a virus that blocks access to settings
- ๐ ๏ธ You need to reflash the phone (for example, after an unsuccessful update)
To log in in Recovery:
- Turn off the phone (press and hold the power button for 10-15 seconds).
- Press the button combination:
- Samsung:
Volume up + Power + Bixby(orVolume up + Power) - Xiaomi/Redmi/Poco:
Volume up + Power - Google Pixel:
Volume down + Power - OnePlus:
Volume up + Volume down + Power
- Samsung:
In the Recovery menu, use the volume buttons to navigate and the power button to select Next:
- Select
Wipe data/factory reset. - Confirm the action (
Yes โ Delete all user data). - After completion, select
Reboot system now. - ๐ฅ๏ธ A computer with installed drivers ADB i Fastboot
- ๐ USB cable (preferably original)
- ๐ง Enabled USB debugging in the developer settings
โ ๏ธ Attention: On some devices (for example, Huawei or Honor) after resetting via Recovery, you may need to enter an unlock code that is generated on the manufacturer's website. Make sure that you have access to the Internet on the other device.
Method 3: Formatting using ADB (for experienced users)
If standard methods do not work (for example, the sensor does not respond, but USB debugging is enabled), you can use Android Debug Bridge (ADB). This method requires:
Instructions:
- Connect your phone to the PC and open the command line (
Win + R โ cmd). - Check the connection with the command:
adb devicesIf the device is displayed, proceed further.
- Reset:
adb shell recovery --wipe_dataOr for a complete wipe (including cache):
adb shell recovery --wipe_data && adb shell recovery --wipe_cache - After completion, reboot the device:
adb reboot
If USB debugging was not enabled in advance, this method will not work. In this case, the only option left is hard reset via testpoints (requires disassembling the device) or contacting a service center.
ADB commands allow you to reset the phone even with a non-working screen, but only if USB debugging was activated IN ADVANCE.
Formatting an external memory card (SD)
If you use memory card. microSD as additional storage, it can also be formatted. This is useful if:
- ๐ The card has become โrawโ (not detected or asks for formatting)
- ๐ฆ Viruses were detected on it
- ๐ You need to change the file system (for example, from
FAT32toexFAT)
Format methods:
| Method | When to use | Instructions |
|---|---|---|
| Through Android settings | The card is determined by the system | Settings โ Storage โ SD card โ Format |
| Via PC | The card cannot be read by the phone | Connect the card to the computer via a card reader and use standard formatting in This computer |
| Via Recovery | You need to clean both the card and the phone | In the Recovery menu, select Wipe โ Format SD card |
| Via SD Formatter | The card is damaged or works slowly | Download the utility from the website SD Association and perform a full format |
โ ๏ธ Attention: If the memory card was used as internal storage (function Adoptable Storage in Android 6+), formatting it via a PC will cause the system to crash. In this case, format only through the phone settings or Recovery.
What to do after formatting: initial setup
After resetting, the device will start in initial setup mode. Follow the instructions on the screen, but pay attention to the key points:
- ๐ถ Connecting to Wi-Fi: Use a reliable network, as you will need to download updates.
- ๐ Login to your Google account: Enter the details of the same account that was linked before the reset (if FRP is enabled).
- ๐ฑ Data recovery: If you made a backup via Google, the system will offer to restore contacts, applications and settings.
- ๐ Setting up a lock: Set a new PIN code or pattern (do not use simple combinations!).
If after resetting the phone asks you to enter the old password for your Google account that you donโt remember, do not try to guess it multiple times - this may block the device for 24 hours. Instead, restore access to your account through a browser on another device.
After completing the setup:
- ๐ฒ Install critical applications (messengers, banking apps).
- ๐ Check for system updates (
Settings โ System โ Software update). - ๐ก๏ธ Set up an antivirus (for example, Google Play Protect or Dr.Web).
