Safe Mode - HTC One®

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 / run slow. Our Troubleshooting Assistant can help you with other device issues if you aren't currently using the tool.

Warning Fast boot must be disabled.

Note Notes:

  • Safe Mode temporarily disables all apps that have been installed via Google Play. Performing this troubleshooting step is necessary to determine whether a third-party app is the cause of an operating system / app issue. Safe Mode should always be performed prior to a hard (factory) reset.
  • With Safe mode enabled, test device and app functionality. If the previous issue fails to occur, the cause has been isolated to a third-party app and all recently installed/updated apps should be uninstalled. With Safe mode disabled, reinstall then test each app, one at a time, to identify which is causing the problem.
