Factory Data Reset (Powered Off) - Samsung Galaxy S9 / S9+

A factory data 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.

Caution Caution:

  • If the device is responsive and can be powered on, the preferred reset method should be performed.
  • For devices with Android Device Protection turned on, it's imperative Google sign-in credentials are known prior to completing a factory reset with the device powered off. If credentials are unknown:
    • Attempt to sign in with any Google™ account previously used on the device.
    • Reset the password.
  • Perform a factory data reset only if absolutely necessary as it removes all data including:
    • Contacts
    • Email accounts
    • System and app data
    • App settings
    • Downloaded apps
    • Media (Music, pictures and videos, etc.)

 

Note Notes:

  • If a pattern, PIN, etc. is or has ever been set up on the device, Google account sign in is required during initial setup.
  • Wi-Fi Calling settings don't transfer after switching devices and/or performing a factory data reset. You need to enable W-Fi Calling manually if you want to use it.
