A new thing i discovered with the Jelly Bean update on my Razr Maxx if you want to Reboot into Safe Mode all one needs to Do is Tap your power button as you would normally shut off your Razr or Maxx were it says Power off take your finger and long press for a few seconds and it will show the screen like this).
( I included a Screen shot of this feature ) when it Does this Tap Ok to Reboot to safe Mode.. This is a Good tool to use when your Apps are not working as they should and it can help ya find the Trouble makers.. b33
