How to reset settings on a Samsung A31

Galaxy A series smartphones such as Samsung Galaxy A31may begin to slow down over time due to the accumulation of system garbage, application conflicts, or software glitches. When standard clearing the cache or deleting unused software no longer helps, the only effective solution is a complete return to its original state. This procedure deletes all user data, returning the device to the state it was in when purchased in the store.

Before you begin the process, it is important to understand the difference between a simple restart and Hard Reset. A normal reboot only updates the RAM, while a factory reset completely erases the partition with user data. This is a radical measure, but often it is what saves the phone from endless freezes or blocking by malware.

In this article we will examine in detail the two main ways to perform this operation: through the system settings menu if the phone turns on, and through recovery mode Recovery Modeif the device does not boot or is blocked. We will also pay attention to critical preparatory steps that will help avoid irretrievable loss of valuable information.

Preparing the device for a full reset

The most critical stage is saving your data. After confirming the factory reset operation, all photos, contacts, messages and installed applications will be destroyed without the possibility of software recovery. Therefore, creating a backup copy is a prerequisite before starting any manipulations.

Use the built-in ecosystem tools Samsung or third-party cloud services. The most reliable option is synchronization with your account Google i Samsung Cloud. Make sure your contacts, calendar and notes are successfully uploaded to the server. For photos and videos, the best option is the service Google Photos or manually copying files to your computer via a USB cable.

⚠️ Attention: Resetting the settings deletes the encryption keys for the internal memory. Even if you use data recovery apps on your computer, the chances of getting your files back after a Factory Reset are close to zero.

Don't forget to check the battery charge. The process of formatting a data partition requires stable power. If the phone turns off while writing system files, this can damage the bootloader and turn the device into a brick. It is advisable to have at least 60-70% charge or connect the charger directly.

Reset through the settings menu (Soft Reset)

This method is suitable for devices that work properly, turn on and allow you to enter the menu. It is the most secure and simplest for the average user. The shell interface One UI on Samsung Galaxy A31 may differ slightly depending on the version of Android, but the logic of the actions remains the same.

First, open the main menu and find the icon Settings. Scroll down the list to item General settings (or General Management). This is where system management tools are concentrated, including reset options. Select the section Reset.

Several options will appear on the screen, but we are only interested in Reset data. The system will show a list of applications and data that will be deleted. Please review the list carefully to make sure you didn't miss anything when creating a backup. Press the button Reset at the bottom of the screen.

• 📱 A warning about entering a PIN code, pattern key or unlock password will appear on the screen.
• 🗑️ Confirm the action by clicking the button Delete everything in the dialog box that appears.
• ⏳ The device will automatically reboot and begin the cleaning process, which may take from 5 to 15 minutes.

Once the procedure is complete, the phone will turn on like new, greeting you with the initial language setup and Wi-Fi connection screen. All your old settings, including screen brightness, sounds and widget locations, will be returned to default values.

Hard Reset via Recovery mode

If the smartphone does not turns on, stuck on the logo or you forgot the pattern key, the only way out is to use recovery mode Recovery Mode. This method works on the hardware level and does not require access to the Android desktop. On models Samsung with version Android 11 and higher, entering this mode has its own characteristics.

An important feature of new firmware One UI: to enter Recovery the phone often needs to be connected with a USB cable to a switched on computer. Simply holding down the buttons without connecting to a PC may not work on some software versions. Connect the cable to the phone and to the computer (or laptop), making sure that the PC is turned on.

Press the button Volume Up and the button Powerat the same time. Keep them pressed until the logo Samsungappears, then release the Power button, but continue to hold the Volume button until a black screen with a menu in English appears. If the phone is turned off, the combination is the same: hold down the buttons, connect the cable (if required), wait for the menu to appear.

⚠️ Attention: In Recovery mode, the touch screen does not work. Navigation is carried out only with the volume buttons (up/down), and the selection is confirmed with the power button.

Using the volume keys, move the selection to the item Wipe data/factory reset. Press the Power button to confirm. Next, the system will ask for final confirmation: select Factory data reset and press the power button again. The formatting process will begin.

What to do if Recovery is not included?

If the button combination does not work, try connecting the phone to a wall charger and not to the computer. On some older firmware versions, connection to a PC is not required. Also make sure that the phone is completely turned off before starting the procedure.

FRP Lock and accounts

Modern Android devices are equipped with a security system FRP (Factory Reset Protection). This feature links the device to the last Google account entered. After performing a reset, even through Recovery, the first time the phone is set up, it will require you to enter the email and password from the account that was synchronized before the reset.

This is done to protect against theft: if an attacker steals the phone and tries to reset its settings, he will not be able to use the device without the owner’s data. Therefore, it is critical to remember your credentials. If you are selling your phone, be sure to delete your Google account in the settings before resetting.

Action	Through Settings	Via Recovery
Deleting data	Full	Full
Google account requirement	No (if deleted in advance)	Yes (required)
Risk of software damage	Minimal	Medium (during power failure)
The need to turn on the screen	Yes	No

Ignoring this protection mechanism may result in the phone remaining locked forever. It is impossible to bypass FRP in legal ways without account data, since this is a security vulnerability that the manufacturer strives to close in every update.

Solving common problems after a reset

Sometimes, after completing the recovery procedure, users encounter unexpected system behavior. For example, the phone may take a long time to load (up to 10-15 minutes) on the screen with a logo Android or loading animation. This is a normal situation, as the system optimizes applications and recreates the directory structure.

If the device is stuck in a bootloop, try resetting again, but this time through Recovery Mode, after selecting the item Wipe cache partition (clear cache partition). This will remove temporary system application files that may have become corrupted and causing a boot conflict.

In rare cases, it may be necessary to flash the device through a app Odin on your computer. This is necessary if the system partition was damaged or the software update was interrupted at the time of the reset. However, for Samsung Galaxy A31 the standard Factory Reset procedure is usually enough to solve 99% of software problems.

• 🔋 If the phone quickly discharges after a reset, let it work for a couple of hours: the system needs time to index files and configure background services.
• 📶 Problems with Wi-Fi or Bluetooth are common are solved by re-pairing the devices and forgetting the old networks in the settings.
• 📲 The lack of a network signal may be due to the fact that the reset returned the access point (APN) settings to the factory settings - check them with your operator.

⚠️ Attention: Interfaces and menu items may vary slightly depending on the firmware version and the regional version of the device. Always check the latest manuals on the manufacturer's official support portal.

Frequently asked questions (FAQ)

Will the SD card be deleted during a factory reset?

By default, when you select “Reset data” in the menu, the internal memory is formatted, but the SD card remains intact. However, in some older versions of the software or when using specific utilities, the “Empty SD card” checkbox may appear. Always read the on-screen warnings carefully before pressing the confirm button. For complete safety, it is better to physically remove the memory card before the procedure.

Is it possible to interrupt the reset process if it is frozen?

Interrupting the formatting process is highly not recommended, as this can damage the file system. If the progress indicator does not move for more than 30-40 minutes, you can try a forced reboot by holding down the Volume Down and Power buttons for 10-15 seconds. But be prepared for the fact that after this the phone may not boot and will require flashing.

Will this reset Android system updates?

No, resetting to factory settings (Factory Reset) only returns user data and application settings to their original state. The Android operating system version and security patch level will remain the same as they were installed at the time of the reset. It is impossible to roll back the Android version to an older one through a regular reset.

What should I do if the phone asks for a password after resetting, but I don’t remember it?

It was the FRP protection that worked. You need to enter the details of the Google account that was the main one on this device before the reset. If you don't remember your password, try recovering it through the Google account recovery form on another device (computer or phone). Without this data, it will not be possible to legally unlock the device.
