Full reset of the smartphone Samsung is a radical, but often necessary measure to restore the device to functionality or prepare it for sale. This operation removes all user data, settings, and installed applications, returning the system to its factory state. Many users confuse regular cache clearing with full formatting, which can lead to unexpected results if the goal was deep cleaning.
The reset procedure affects not only visible files in the gallery, but also hidden system partitions where error logs and temporary data of Google services are stored. Before starting any manipulations, it is critical to understand the difference between a soft reset and hard formatting via Recovery mode. Incorrect actions can block the device through the protection system FRP (Factory Reset Protection) if certain preliminary preparation conditions are not met.
In this guide we will analyze all available methods of returning your Galaxy to its original state, taking into account the features of modern shells One UI. We will pay special attention to the nuances of deleting accounts and bypassing locks, which inexperienced users often experience after a forced restart.
Preparing the device for a complete data reset
Before initiating the data destruction process, it is necessary to perform a number of mandatory actions, ignoring which may make the phone unsuitable for further use by the new owner. The most critical stage is unlinking the account Google i Samsung Account. If this is not done, the first time you turn it on after a reset, the system will ask for a password from the last synchronized account, and without it it will be extremely difficult to unlock the device.
It is also worth taking care of the safety of valuable information. Even if the goal is to sell a phone, you may need contacts or photos in the future. Use cloud services or transfer data to a PC via Smart Switch. Make sure that the battery charge is at least 50-60%, since the process of formatting the data partition is energy-intensive and interruption on a low charge can damage the file system.
⚠️ Attention: Removing a Google account must be done through the settings menu, and not just resetting the phone. A simple reset without logging out of your account will activate anti-theft protection.
☑️ Preparing for reset
Check for the presence of a memory card microSD. In modern versions of Android, the reset often offers the option to format the external card. If you plan to use it on another device, it is better to physically remove it before starting the procedure to avoid accidentally deleting media files.
Reset through the standard One UI settings menu
The most secure and recommended way to reset a device is available directly from a running operating system. This method ensures that all background processes are closed correctly and memory partitions are properly erased. The path to the desired function may differ slightly depending on the version Android, but the logic remains the same for the entire line Samsung.
Go to the main menu and find the settings icon. You need to open the section General settings (General Management). This is where the system management tools, including reset, are concentrated. Please note that on some models with a simplified interface, this item may be called simply Reset and is located in the main list without nesting.
Select item Reset data. The system will show a list of applications and data that will be deleted. This is your last chance to change your mind or check if you forgot something important. Pressing the button Reset settings will start the process, which may take from 5 to 15 minutes depending on the amount of full memory and the speed of the drive eMMC or UFS.
If the phone asks for a PIN code or pattern key before resetting, enter the one that is used to unlock the screen, and not the account password.
After the procedure is completed, the device will automatically reboot. The initial setup will look like you just took the phone out of the box: selecting a language, connecting to Wi-Fi and logging into your account. Old data on the internal drive will be irretrievably lost and overwritten with zeros or random data, depending on the encryption implementation.
Hard Reset via Recovery mode
Sometimes the situation is such that it is impossible to get into the settings menu: the phone is frozen, the pattern key is forgotten, or the system boots in a loop. In such cases, the regime Recoverycomes to the rescue. This is a special diagnostic section recorded in a protected memory area, which allows you to control the device at a low level, bypassing the main operating system.
To enter this mode on modern smartphones Samsung with Android 11 and higher, you often need to connect a USB cable to a switched-on computer. This change has been implemented for security purposes to prevent unauthorized dumping of stolen devices. The key combination usually involves holding down the button Volume Up and Power at the same time.
As soon as the logo appears Samsung, release the power button, but keep holding the volume up until a black menu screen appears. Navigation here is carried out with the volume buttons, and selection is done with the power button. You need to find the item Wipe data/factory reset. Be extremely careful: selecting the item Wipe cache partition will not delete your data, but only temporary files, which will not solve the problem of complete cleaning.
⚠️ Attention: In Recovery mode, the touch screen does not work. All actions are performed exclusively with the physical volume and power buttons.
Nuances of entering Recovery on different models
On models with a physical Home button (for example, S7, J7), you need to hold down Volume Up + Home + Power. On models with Bixby (S8, S9, Note 8, Note 9) the combination is the same, but Bixby is used instead of Home. On new models without buttons (S20, S21, A52 and newer), it is necessary to connect to the PC via USB.
After selecting the reset item, the system will ask for confirmation, usually this is selecting a line Yes or Factory data reset. The process will go quickly, since animations are not displayed in this mode. When finished, select Reboot system now. The phone will reboot, and the first boot time may be increased to 10 minutes due to application optimization.
Deleting accounts and FRP protection
The protection system FRP (Factory Reset Protection) was implemented by Google to combat the theft of smartphones. The essence of its work is simple: if a Google account was added to the device, then after resetting the settings (especially done through Recovery), upon activation you will need to enter the password for this account. This makes the phone useless to a thief, but can be a problem for an honest owner who has forgotten the password.
To avoid an FRP lock, you must delete your account before resetting. Go to Settings → Accounts and Backup → Manage Accounts. Select the desired Google account and click Delete. Repeat the procedure for Samsung Accountas it may also require authentication on some models.
| Reset method | Requires exit from Google | Risk of FRP blocking | Difficulty of implementation |
|---|---|---|---|
| Through the settings menu | Preferable, but not strictly mandatory | Low (the system will check itself) | Low |
| Through Recovery (buttons) | Required | High (blocking guaranteed) | Medium |
| Via Find My Mobile | Automatic | Absent | Low |
If you have forgotten your account password, you can restore access through your browser on another device via the link accounts.google.com. After changing the password, you may need to wait 24 hours before attempting to enter new data on the reset phone - this is a Google security measure.
Remote reset via the Find My Mobile service
Smartphone owners Samsung have a unique advantage - the service Find My Mobile. If your phone is connected to the Internet and you are logged into your Samsung Account, you can completely reset it remotely, even if the screen is locked or the device is in the possession of another person (for example, lost and found).
To do this, go to the official website of the service from any computer or other phone. After authorization, select the one you need from the list of devices. In the side menu, find the option Erase data (Erase data). The system will warn you about the consequences and ask for your Samsung account password for confirmation.
The main advantage of this method is that it correctly removes the FRP lock, since the command comes from the manufacturer’s trusted service. The phone will receive the signal, reset, and reboot, ready for a new setup without asking for old passwords. This is an ideal way to prepare a found or forgotten phone for use.
⚠️ Note: For this method to work, the phone must be turned on and have an active connection to a mobile network or Wi-Fi. If the device is turned off, the command will be executed immediately after it is turned on.
What to do after a complete reset
After the phone has booted into its initial state, you will be faced with the task of initial setup. Don't rush to restore all your data from a backup at once. First, update the software by going to Settings → Software update. This will close security vulnerabilities that could be in the factory firmware.
When restoring data via Google Drive or Smart Switch select only the necessary elements. Often, along with contacts and photos, the very applications or settings that could cause problems before the reset are also restored. It is better to install applications again from Play Market or Galaxy Store.
Pay attention to the security settings. Enable Google Play Protect and, if necessary, configure biometric protection (fingerprint, face). Check to see if there are any old user profiles left in the memory if you used the mode Multiple users before the reset.
After the reset, be sure to install all available system and security updates before installing third-party applications to ensure maximum device protection.
Possible problems and their solution
Despite the simplicity of the procedure, users may encounter a number of difficulties. One of the most common is getting stuck on the logo Samsung after a reset. If the phone hangs on the screen saver for more than 15 minutes, try to force a reboot by holding Volume Down and Power for 10-15 seconds.
Another problem is a formatting error. This may indicate a physical problem with the flash memory. In this case, software methods are powerless, and you need to contact a service center to replace the board or memory chip. It is also possible that the message “No command” appears in Recovery mode - in this case, simply hold down the power button and press the volume up once.
If after resetting the phone says “Previous owner” and requires a password that you do not know, it means that the procedure for logging out of the account was not completed. This can only be solved by restoring access to the account through Google support or, in extreme cases, by flashing the device via a computer using special software, which requires qualified skills.
Why does the phone slow down immediately after a reset?
In the first hours after resetting, the system is engaged in background indexing of files, updating applications and optimizing the database. This is fine. Let the phone work connected to Wi-Fi and charging for about an hour, and performance will return to normal.
Will a hard reset remove the Android operating system?
No, the operating system is not removed. The reset only affects the user data partition (/data) and cache (/cache). The system partition (/system), where the OS itself and pre-installed applications reside, remains untouched. The Android version will remain the same as that installed before the reset.
Is it possible to restore data after resetting the phone?
On modern smartphones with encryption enabled, data recovery after a factory reset is almost impossible. The encryption keys are deleted along with the data, making the residual information on the memory chip unreadable. Specialized recovery software is usually powerless against hardware encryption.
What should I do if the phone asks for a password for an account that I deleted before resetting?
This may happen due to a delay in server synchronization. Try waiting 1-2 hours and re-entering. If you deleted your account less than 24 hours before the reset, Google's security servers may still consider your device linked. In this case, only waiting or restoring access to this specific account will help.
Will resetting erase data on the SD memory card?
By default, an internal reset does not affect the external memory card. However, the reset menu often has a "Empty SD card" checkbox. If you haven't marked it, the data will remain on the map. When resetting via Recovery, the memory card is usually not formatted unless the corresponding option is selected in the extended menu.
How to reset the phone if the screen is broken and the sensor does not work?
If the sensor does not work, but there is an image, you can try connecting a USB mouse via an OTG adapter. This will allow you to control the cursor and go into the settings to reset. If the screen is black, but the phone vibrates when making a call, only the Recovery mode (buttons) or the Find My Mobile service will help, if it was configured in advance.
