How to Factory Reset a Samsung Galaxy S8

To factory reset a Galaxy S8, use Settings if the phone opens normally, or use the hardware buttons to enter Android Recovery if Settings is unavailable. A factory reset erases the phone’s personal data and returns its software settings to their factory state.

What should you do before resetting a Galaxy S8?

A factory reset for Galaxy S8 phones removes personal data stored on the device, including accounts, downloaded apps, messages, photos, files, and changed settings. Data already synchronized with an online account or saved in a separate backup may remain available, but confirm that the backup exists before erasing the phone.

Before starting a factory reset Galaxy S8 procedure:

• Back up any photos, contacts, messages, documents, and other information you want to keep.
• Make sure you know the Google Account email address and password previously used on the phone.
• Confirm that you can access any Samsung account connected to the device.
• Remove the microSD card if you do not want it present during the reset. A standard factory-data reset targets internal device storage, but removing the card helps prevent accidental changes.
• Charge the phone or connect it to reliable power so it does not shut down during the reset.
• If you are giving the phone to someone else and can still use Settings, remove your Google and Samsung accounts before resetting it.

Do not begin until you accept that locally stored information may be unrecoverable afterward.

How do you factory reset a Galaxy S8 through Settings?

Use the Settings method when the Galaxy S8 can be unlocked and its menus work normally. The exact wording may vary slightly with the installed software version.

1. Open Settings.
2. Select General management.
3. Select Reset.
4. Select Factory data reset.
5. Review the accounts, apps, and information shown on the reset screen.
6. Scroll down and select Reset.
7. Enter the current screen-lock PIN, password, or pattern if requested.
8. Select Delete all to confirm.

The Galaxy S8 will erase its internal data and restart. Do not force the phone off while the reset is in progress.

How do you factory reset a Galaxy S8 with the hardware buttons?

Android Recovery is a separate maintenance menu that can erase the phone when Android or Settings cannot be opened. Use this procedure only when you cannot complete the normal Settings reset.

1. Turn the Galaxy S8 completely off. If it will not respond or power off safely, contact Samsung support instead of repeatedly forcing restarts.
2. Press and hold the Volume Up, Bixby, and Power buttons together.
3. When the Samsung logo appears, release the buttons and wait for the Android Recovery menu.
4. Use the volume buttons to highlight Wipe data/factory reset.
5. Press the Power button to select it.
6. Use the volume buttons to highlight the confirmation option, such as Yes or Factory data reset.
7. Press the Power button to confirm.
8. When the recovery menu returns and Reboot system now is highlighted, press the Power button.

The touch screen may not work in Android Recovery; use the volume buttons to move and the Power button to select. Be careful not to choose another recovery command.

What should you do if the Galaxy S8 requests a previous account?

After a hardware-button reset, the Galaxy S8 may request a Google Account that was previously synchronized with the phone. This security check is called Factory Reset Protection, and it helps prevent an erased device from being used without the account owner’s permission.

Enter the Google Account email address and password that were used on the Galaxy S8 before the reset. If you forgot them, use Google Account Recovery from another device. If the setup screen asks for a Samsung account, use Samsung’s official account-recovery process through the company’s official website.

Recently changed credentials may not be accepted immediately because of account-security protections. Follow the instructions shown by the official recovery service. There is no legitimate reset procedure that removes account ownership verification, and unofficial bypass instructions can compromise the phone or account.

What should you do if the Galaxy S8 will not reset?

If the factory reset Galaxy S8 process fails, connect the phone to reliable power and try the appropriate procedure once more. Check that you selected Wipe data/factory reset, confirmed the erase command, and then selected Reboot system now.

• If Android still opens, use the Settings method instead of Android Recovery.
• If the buttons do not respond, remove any case that may be blocking them and try again.
• If the phone repeatedly restarts, shows an error, becomes unusually hot, or cannot remain powered on, stop retrying.
• If Android Recovery displays unfamiliar warnings or commands, do not experiment with other options.

Open the company’s official website and use the support section to contact official Samsung support. Have the phone’s model information and proof of ownership available if requested. Samsung support can explain approved service options without bypassing device security.

How do you set up a Galaxy S8 after the reset?

After the Galaxy S8 restarts, follow the on-screen setup instructions. Choose a language, connect to an available Wi-Fi network, and sign in with the appropriate Google or Samsung account when prompted.

If a backup is offered during setup, review its account, date, and contents before selecting it. Restore only a backup you recognize. Items that were never backed up or synchronized cannot be restored through account setup.

Finish the security prompts, create a new screen lock, and allow the phone to complete any available restoration. Check important contacts, photos, and files before relying on the device again.
