Users regularly encounter situations where a complete cleaning of the smartphone is required. This may be due to selling the device, transferring it to another family member, or the need to resolve critical software glitches. The process of returning a gadget to its original state, known as Factory Reset, is a radical, but often the only correct measure to restore the system's functionality.
Before starting the procedure, it is necessary to realize the irreversibility of actions. All your personal files, photos, contacts, message history and installed applications will be permanently deleted from the device's internal memory. The operating system Android will return to the state in which it was immediately after unpacking the box. Therefore, preliminary creation of a backup copy of critical data is a mandatory step, ignoring which can lead to loss of information.
In this guide, we will examine in detail the two main methods of performing this operation: through the settings menu of a working device and using the control buttons in Recovery mode. The nuances of protection against theft through a Google account and reset features on devices from different manufacturers will also be discussed.
Preparing the device for a full data reset
Immediately before initiating the cleaning process, you need to perform a number of preparatory steps. This will ensure the safety of your data and prevent possible problems with activating the device after a reboot. The most important step is to synchronize your contacts, calendar and notes with cloud storage.
Make sure that synchronization with servers Google was successful. Go to your account settings and check the latest update status. If you have important files in your downloads folder or documents, copy them to your computer or cloud storage such as Google Drive or Yandex.Disk.
⚠️ Attention: If you plan to sell the phone, be sure to delete Google account from settings before resetting. Otherwise, FRP (Factory Reset Protection) protection will work, and the new owner will not be able to activate the device without your password.
The second critical point is the battery charge. The process of formatting internal memory and reinstalling system partitions consumes energy. If the phone turns off at the most critical moment, this can damage the bootloader and turn the smartphone into a “brick”. The charge level should be at least 50-60%.
☑️ Preparing to reset the settings
Don't forget to remove the memory card microSDif it is installed in the slot. Although modern versions Android usually ask whether to format the external card, physically removing the media guarantees 100% safety of your media files stored on it.
Resetting through the settings menu of a running system
This is the safest and easiest method available to the user if the smartphone turns on and the screen responds to touches. The interface may differ slightly depending on the manufacturer's shell (MIUI, OneUI, ColorOS), but the logic of actions remains the same for the entire ecosystem.
Open the “Settings” application and scroll the list to the very bottom. You need to find the section responsible for general system parameters. It is usually called "System", "General Settings" or "Advanced Settings". Inside this section, look for an item containing the word “Reset” or “Restore.”
On a clean Android path often looks like this: Settings → System → Advanced → Reset settings. On devices Samsung the route can be like this: Settings → General management → Reset. Owners Xiaomi should look for the item in the "Advanced settings" → "Recovery and reset" section.
After selecting “Reset data” or “Delete all data”, the system will show a list of what will be deleted. Please read the list carefully. When you press the confirm button, your device will ask you to enter your PIN, pattern, or screen unlock password. This is a security measure to prevent accidental or unauthorized reset.
After confirmation, the phone will reboot and begin the deletion process. The manufacturer's logo or robot animation may be displayed on the screen. Do not touch the device at this time. The process may take from 5 to 15 minutes depending on the amount of full memory and the speed of the drive. Android. Do not touch the device at this time. The process may take from 5 to 15 minutes depending on the amount of memory used and the speed of the drive.
If the phone asks for a password for your Google account after resetting, and you don’t remember it, try restoring access through your computer before starting the reset procedure.
Hard Reset via Recovery mode (for locked phones)
If the device is frozen, does not load to the desktop or you forgot the pattern key, the only way out is to use Recovery Mode. This method is called Hard Reset and is performed using physical control buttons.
To enter Recovery mode, you must first turn off your smartphone completely. Then you need to hold down a certain key combination. On most devices, this is the power button along with the volume up button (Volume Up). On some models Samsung you may need to connect the USB cable to the computer while pressing the buttons.
Hold the buttons until the logo or recovery menu appears. Navigation in this menu is carried out using the volume buttons (up and down), and the selection of an item is confirmed with the power button. You need to find the line Wipe data/factory reset.
⚠️ Attention: In Recovery mode, the touch screen does not work. Be extremely careful when navigating the buttons so as not to select the clear cache option instead of a full reset, or vice versa.
After selecting the reset item, the system will ask for confirmation, usually requiring you to select Yes or Factory data reset. Confirm the action. The data and cache partitions will begin formatting. When the process is complete, select Reboot system now to reboot the device.
What to do if the Recovery menu does not appear?
On some new smartphones, logging into Recovery is only possible when the computer is connected via USB. Try holding down the power and volume buttons while simultaneously connecting the cable to the PC. If it doesn’t help, try a combination with the volume down button.
The first boot after a Hard Reset always takes longer than usual. The system reinitializes the partitions and prepares the environment for work. Be patient and do not try to interrupt this process by pressing buttons.
Deleting a Google account and FRP protection
The anti-theft mechanism (FRP - Factory Reset Protection) is an integral part of security Android since version 5.1. Its essence is to link the device to the last entered Google account. After resetting the settings, the phone will require you to enter the password for this account during the first setup.
This creates a problem when selling the phone. If you reset without first deleting the account, the buyer will be faced with an activation lock screen. He will not be able to use the phone until you enter your data remotely or provide a password.
| User action | Google account status | Result after reset |
|---|---|---|
| Deleting an account in settings | Untied from the device | The phone is activated without a password |
| Reset without deleting the account | Linked (FRP active) | Requires entering the owner's password |
| Reset via Recovery | Bound (FRP active) | Requires entering the owner's password |
To correctly prepare the device for transfer to another person, go to the menu Settings → Accounts (or “Users and accounts”). Select your Google profile and click the "Delete Account" button. Repeat this procedure for all added accounts, including social network profiles, if they are integrated into the system.
Only after your data is no longer in the list of accounts can you proceed with_factory reset_. In this case, FRP protection will not work, and the new owner will be able to customize the phone for himself by entering his own username and password.
Selling a phone without first logging out of your Google account will make the device useless for the buyer due to activation lock.
Reset features on popular brands
Various smartphone manufacturers make their own changes to standard interface Android, which affects the menu layout and item names. Knowing these nuances will save time when searching for the desired function.
Devices Samsung with shell One UI often require confirmation of the action by entering the screen unlock PIN code at the very end of the process, before the “Reset” button. Also, on new models, a warning may appear that the password has changed in the last 24 hours, and reset will be available only after 24 hours - this is protection against theft.
Smartphones Xiaomi, Redmi and Poco based MIUI have additional protection. When you try to reset through settings, the system may require you to enter the password for your Mi account. This is done so that an attacker cannot erase the data of a stolen phone.
On phones Huawei i Honor the reset path may be hidden in the “System and Updates” section. In Recovery mode on these devices, it is sometimes necessary to enter a confirmation code that is displayed on the screen using the volume buttons to confirm the user's intentions.
⚠️ Attention: Shell interfaces are updated regularly by manufacturers. If the described paths do not match your screen, use the settings search by entering the word “Reset.”
Device owners Sony i Motorola are the luckiest: their interface is as close as possible to the stock one Android, so the standard path System → Reset works flawlessly in 99% of cases.
Solving problems after resetting
After successful completion of the procedure and the first boot, the user is faced with the initial setup screen. It is important to act consistently here. Connect to a Wi-Fi network, as some services require Internet access to activate some services and check for security updates.
If after a reset your phone continues to function incorrectly, freezes, or discharges quickly, the problem may lie not in the software data, but in the hardware or damage to system files that were not restored automatically. In this case, you may need to flash the device through a computer using special software (Odin for Samsung, Fastboot for others).
It is also worth checking whether there are any hidden folders from old applications left in the internal memory, although a full reset should clear the partition /data completely. If you restored the backup immediately after the reset and the problems returned, then the error is contained in the saved data itself or the application settings.
Why does the phone get warm after the reset?
In the first 1-2 hours after the factory reset, the system indexes files and optimizes applications in the background. This is normal behavior and causes heat and increased battery consumption. Wait a while.
If the device requests an activation code from the previous owner, and it is impossible to contact him, it is extremely difficult to officially unlock the phone. You will need to provide a receipt of purchase to the manufacturer's service center to prove ownership.
What exactly is deleted when resetting to factory settings?
All user data is deleted: photos, videos, music, documents, installed applications and their data, system settings (wallpapers, sounds, Wi-Fi access points, saved passwords). The operating system and pre-installed factory applications remain untouched.
Is it possible to recover data after a Factory Reset?
Restoring data after a full reset on modern smartphones with memory encryption is almost impossible for the average user. Specialized software can help only in rare cases, if the memory has not been overwritten with new data, but there is no guarantee.
Is the Android version reset during a Factory Reset?
No, the operating system version does not change. If you had Android 13 installed, then after the reset you will be left with Android 13. The reset only returns the settings and deletes data, but does not roll back the firmware to an older version.
Do you need to remove the SIM card before resetting?
It is not necessary to remove the SIM card, since resetting the settings does not affect the data on the SIM card (contacts, if saved on it, and tariff settings). However, removing the SD memory card is highly recommended.
How long does the reset process take?
The process usually takes 5 to 15 minutes. The time depends on the amount of internal memory that needs to be cleared and the speed of the device's processor. The first boot after a reset may take longer, up to 10 minutes.
