Samsung Galaxy S9 / S9+ - Power Up in Safe Mode

Safe Mode puts your phone in a diagnostic state (returned to default settings) so you can determine if a third-party app is causing your device to freeze, reset or run slow.

Note An alternate method is available if the device can be powered on and is responsive.

  1. With the device powered off, press and hold the Power button until the device vibrates and the Samsung Galaxy S9 screen appears then release.
