Restarting Your Phone
On rare occasions, you may need to restart your phone to address problems or
to force the sign out of a user who is not present to unlock the phone.
To restart the phone:
¾ Insert a small tool, like a paper clip, into the small reset hole between the
headset jack and the USB port on the back of the phone.
The phone will restart, prompt the user to recalibrate the screen, and then
present either the Sign In screen or the Connect to Computer screen.
Note Restarting the phone will sign out any previously signed-in user and will wipe out
call logs and other data associated with that user.
