Owning a modern smartphone from Samsung implies active use of the device for a long time. Over time, errors, residual files and software glitches accumulate in the system, which can slow down the operation of the gadget. In such situations, the only correct solution is a complete return to the factory state, known as Hard Reset or resetting the settings.
This procedure is necessary not only when selling the gadget to a new owner, but also in preparation for flashing or eliminating critical operating system errors. It is important to understand that the process will completely destroy all user dataincluding photos, contacts and installed applications, therefore it must be approached with maximum responsibility and preliminary preparation.
In this article we will analyze in detail all the available methods of clearing memory, from standard menus to using the engineering mode. You will learn about the intricacies of protecting accounts and the features of working with the file system of modern models of the series Galaxy S i Galaxy A.
Preparing the device for a complete data reset
Before starting any manipulations with system files, you must perform a number of mandatory actions. Ignoring this step may result in the loss of important information or the device being blocked by security mechanisms.
Create a backup copy of all important data. You can use the cloud service Samsung Cloud or Google Drive to save contacts and calendar. It is better to copy photos and videos to a computer or external drive, as they take up the largest amount of memory.
- 🔋 Charge your smartphone battery to at least 50-60% so that the device does not turn off during the cleaning process.
- 📱 Make sure you know the password for your Google account i account Samsung, since after the reset the system will require them to confirm the owner's rights.
- 📴 Remove the SIM card and memory card microSDif you do not plan to clear their contents along with the internal memory.
Please note that the “Find device” function is activated. If you do not unlink accounts before resetting via the menu, the phone may require you to enter a password after rebooting. This is a standard anti-theft measure known as FRP (Factory Reset Protection).
⚠️ Attention: If you have forgotten the password for the Google account linked to your phone, be sure to restore access before starting the reset procedure. Otherwise, you may lose access to the device forever.
Check that you have important passwords for Wi-Fi networks and two-factor authentication in applications. After cleaning, all passwords saved in the browser will be deleted if they are not synchronized with the cloud.
☑️ Checklist before resetting
Method 1: Reset through the standard settings menu
The most secure and simple method available to every user is to use the built-in operating system functionality systems Android with a shell One UI. This method is suitable if you have access to the desktop and phone menu.
To begin, open the Settings application and scroll to the very bottom of the list. Find the "General Settings" or "General Management" section; the names may vary slightly depending on the firmware version. Next, select "Reset".
Several options for action will appear on the screen. You are interested in the "Reset data" option. The system will warn you about what data will be deleted. Carefully read the list, which usually includes:
- 📷 All photos, videos and audio files.
- 📞 Contacts, messages and call history.
- ⚙️ System settings, alarms and Wi-Fi passwords.
- 📲 All applications you have installed and their data.
After confirming the actions, the system may request you to enter a screen unlock PIN or pattern. This is protection against accidental reset by unauthorized persons. Click "Delete All" or "Reset" and the cleaning process will begin.
⚠️ Attention: The data deletion process may take 5 to 15 minutes. Do not interrupt it or try to turn off the phone, even if the screen has gone dark.
After the procedure is completed, the smartphone will automatically reboot. The first startup will take longer than usual, since the system will create a new file structure.
What to do if the menu does not open?
If the interface is frozen and does not respond to touches, try to force a reboot of the device by holding down the power and volume down buttons for 10 seconds. If this does not help, proceed to the method via Recovery Mode.
Method 2: Hard Reset via Recovery Mode
If the operating system does not boot or the touch screen does not respond, recovery mode is used Recovery Mode. On new models Samsung entering this mode often requires connecting a USB cable to the computer.
Turn off the smartphone completely. Connect it with a USB cable to a switched on computer or laptop. Press and hold the Volume Up button and the Power button (or Side button) at the same time. Hold them until the logo appears Samsung, then release.
A menu with a text interface will appear in front of you. Control here is carried out with the volume buttons (up/down), and the choice is confirmed with the power button. You need to find the "Wipe data/factory reset" item.
Select this item and confirm the action by selecting "Factory data reset" or "Yes". The system will begin formatting the partitions. After successful completion, select "Reboot system now".
On models with Android 11 and higher, a connection to a PC is required. Without a cable, the phone can simply go into fast charging mode instead of Recovery.
This method is deeper and is often used by service center technicians. It ignores software interface locks, but does not bypass Google FRP protection.
Comparison of reset methods and their features
Users often wonder which method is best to use. Both methods lead to the same result - complete deletion of user data. However, there are nuances depending on the situation.
The menu-based method is more gentle on the system, since it correctly closes all processes before cleaning. The Recovery method may be necessary if there are system errors that block normal operation.
| Characteristics | Through the settings menu | Through Recovery Mode |
|---|---|---|
| Availability | Requires a working interface | Works even if the OS crashes |
| Difficulty | Low (automatic) | Medium (buttons needed) |
| PC connection | Not required | Often required for new models |
| Risk of errors | Minimal | Average (human factor) |
Choose a method depending on the current state of yours Galaxy. If the phone turns on and works, use the settings. If it hangs on the logo or does not respond, only Recovery.
Remote reset through the Find My Mobile service
The company Samsung provides a unique opportunity to remotely control the device. If you have forgotten your password or lost your phone, but it is connected to the Internet, you can reset it through the service Find My Mobile.
To do this, you must first log in to your account Samsung on the device and enable the “Remote Control” function. Go to the official website of the service from any computer or other smartphone.
Login using your account. From the list of available options, select "Erase data" or "Wipe data". The system will send a command to the device and it will begin the cleaning process even if you do not have physical access to it right now.
⚠️ Note: Remote reset is only possible if there is an active Internet connection (Wi-Fi or mobile data) on the target device.
This feature is also useful in situations where the touch screen is broken, but the image is visible on it is, and you can see that the phone is connected to the network.
What to do after resetting
After the process is completed and the phone turns on, you will see a welcome screen, just like when you first launch from the store. You will have to go through the initial setup Android.
Connect to a Wi-Fi network to activate the device. The system will ask you to enter your Google account. Enter the same data as previously used to avoid blocking and restore synchronization.
During the setup process, the system will offer to restore data from a backup copy. Select the date of the last backup you created during the preparation phase. This will restore contacts, a list of applications and some settings.
- 🔄 Wait until system updates are installed, if they are offered.
- 📲 Enter the Play Market and update all applications to the latest versions.
- 🔒 Set up new biometric security methods (fingerprint, face).
Do not rush to install hundreds of applications at once. Give the system time to optimize in the background. In the first hours after the reset, the phone may become hotter and drain battery faster.
Correct setup after the reset takes longer than the reset itself. Do not skip the security update steps.
