How to Reset a Galaxy S8 to Factory Settings

Updated 2026-08-25 · 1056 words

A Galaxy S8 reset to factory settings erases the phone and returns its software settings to their factory defaults. For a working phone, use Settings; for a locked or unresponsive phone, use the Android Recovery menu with the hardware buttons.

What should you do before you reset your Galaxy S8?

A factory reset removes personal files stored on the Galaxy S8, downloaded apps, accounts, messages, and customized settings. Information saved only on the phone may not be recoverable after the reset.

Before starting a Galaxy S8 reset to factory settings, complete these checks:

  • Back up photos, videos, contacts, messages, documents, and other information you want to keep.
  • Make sure synced information has finished uploading to the account or backup service you use.
  • Confirm that you know the email address and password for the Google account currently associated with the phone.
  • Confirm your Samsung account credentials if you plan to restore information from that account.
  • Remove the microSD card if you do not want it involved in the process. A normal factory reset targets the phone’s internal storage, but removing the card helps prevent accidental changes.
  • Charge the battery before beginning. Keep the phone connected to power if its charge is low.

If the Galaxy S8 belongs to an employer, school, or another person, contact the account owner or administrator before erasing it. Device-management restrictions can affect resetting and later activation.

How do you reset the Galaxy S8 through Settings?

Use the Settings method when the Galaxy S8 starts normally, responds to touch, and can be unlocked. The official menu path is Settings > General management > Reset > Factory data reset.

  1. Open Settings on the Galaxy S8.
  2. Select General management.
  3. Select Reset.
  4. Select Factory data reset.
  5. Review the accounts, apps, and information listed on the confirmation screen.
  6. Scroll down and select Reset. Enter the screen lock PIN, password, or pattern if requested.
  7. Select Delete all to confirm.
  8. Wait while the Galaxy S8 erases its internal storage and restarts. Do not turn off the phone during this process.

The exact wording of the final confirmation may vary slightly with installed software updates, but do not choose other reset choices such as resetting network settings if the goal is to erase the entire phone.

How do you factory-reset a locked or unresponsive Galaxy S8?

Android Recovery is a built-in maintenance menu that works outside the normal Android interface. Use it when the Galaxy S8 cannot be opened normally, but remember that the hardware-button procedure still erases personal information and does not remove account verification requirements.

  1. Turn off the Galaxy S8. If it is frozen, hold the Power and Volume Down buttons until the phone restarts, then power it off if possible.
  2. With the phone off, press and hold the Volume Up, Bixby, and Power buttons together.
  3. Release the buttons when the Android Recovery screen appears. The phone may display startup screens before opening recovery, so allow it time to continue.
  4. Use the Volume Down button to highlight Wipe data/factory reset. Touch controls may not work in recovery.
  5. Press the Power button to select the highlighted option.
  6. Use the volume buttons to highlight the confirmation option for deleting user data, then press the Power button to confirm.
  7. Wait for the recovery menu to report that the data wipe is complete.
  8. Highlight Reboot system now and press the Power button.

The first startup after the reset can take longer than a normal restart. Keep the Galaxy S8 powered on while it completes the process.

Why does the Galaxy S8 ask for a Google account after the reset?

Factory Reset Protection, often called FRP, is an Android security feature designed to prevent someone from using a phone after an unauthorized reset. If the Galaxy S8 was reset while a Google account was associated with it, setup may require credentials for a Google account that was previously synced with the phone.

Enter the requested Google account email address and password during setup. If you recently changed the password, account-security protections may temporarily delay sign-in. Use Google’s official account-recovery process from another device if you cannot remember the credentials.

A factory reset does not bypass Factory Reset Protection. There is no supported procedure for avoiding the previous account requirement; if the phone is not yours, the previous owner or authorized administrator must resolve the account association.

What should you do if the Galaxy S8 factory reset does not work?

If the Galaxy S8 does not start the reset or does not enter Android Recovery, try these safe checks:

  • Charge the phone for a while with a known-working compatible charger, then try again.
  • Force a restart by holding Power and Volume Down until the phone restarts.
  • Remove any case that could prevent the Power, Volume, or Bixby buttons from moving normally.
  • Start the hardware-button sequence only after the phone is fully off.
  • In Android Recovery, navigate with the volume buttons and confirm with the Power button instead of tapping the screen.
  • If the phone repeatedly freezes at the logo, becomes unusually hot, has visible damage, or cannot hold a charge, stop repeating the reset.

If these checks do not help, contact official Samsung support or an authorized service location. Be ready to provide the Galaxy S8 model information and proof that you are authorized to use the device. Samsung support cannot supply another person’s Google password or remove legitimate account-security checks without appropriate verification.

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

After the Galaxy S8 restarts, follow the on-screen setup prompts. Choose a language, connect to an available network, accept the required terms, and sign in with the Google account requested by Factory Reset Protection.

When setup offers a restore option, select the backup associated with your account and choose the information you want to restore. Sign in to your Samsung account if your backup was stored there. Apps and synced information may return gradually, depending on the backup and connection.

Set a new screen lock and review account synchronization after setup finishes. Check that important contacts, photos, messages, and documents are present before deleting any separate backup copies. If you intend to transfer the Galaxy S8 to someone else, complete the reset only after removing your accounts through Settings so the next authorized user is not stopped by Factory Reset Protection.
