Restart in Safe Mode - DROID RAZR M by MOTOROLA / Luge™ by Motorola
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.
An alternate method is available if the device is unresponsive or won't power on.
Press and hold the Power button until the options menu appears then release.
Touch and hold Power off until the "Reboot to safe mode" prompt appears (approximately 1 second) then release.
From the "Reboot to safe mode" prompt, tap OK to confirm.
Allow several minutes for the device to power off and restart into Safe Mode.
Upon reboot, "Safe Mode" appears in the lower-left of the unlock screen.
