Power Up in Safe Mode - Casio G'zOne Commando® (C771)

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.

  1. With the device powered off, press and hold the Power button until the device vibrates then release.

Note Notes:

  • 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 or updated apps should be uninstalled.
  • Power cycle the device to disable Safe Mode, reinstall then test each app, one at a time, to identify which is causing the problem.
