Perform a Factory Data Reset (Device Powered On) - Samsung Galaxy S® III

A factory data (hard) reset may help with a blank or frozen screen, apps crashing or freezing, keypad/touchscreen problems, can't hear, device making noises, can't make or receive calls and device won't sync. Our Troubleshooting Assistant can help you with other device issues if you aren't currently using the tool.

Warning Perform a factory data reset only if absolutely necessary as it removes all data including:

  • Google account
  • System and app data
  • App settings
  • Downloaded apps
  • Music, pictures and videos (It's recommended to backup this data).

Note Notes:

 

  1. From a home screen, tap Apps Apps (located in the lower right).
  2. From the Apps tab, tap Settings.
  3. From the Personal section, tap Back up and reset.
    Note To determine if an issue is caused by a third-party app, uncheck Automatic Restore.
  4. From the Personal data section, tap Factory data reset.
  5. Tap Reset device.
    Note If presented, enter the current passcode or draw the unlock pattern.
  6. Tap Delete all.
    Note Allow several minutes for the factory data reset and reboot processes to complete.
    Note If necessary, refer to Initial Activation and Setup.
