A few seconds after it gets a signal after starting up the screen freezes and the keypad locks and it cannot do anything including turning off unless i remove the battery and it is doing this every time! if it is closed the outer screen will show the screen saver but cannot come out of it and the main screen will show the same display as the outer screen and if it is open the main screen won't show the menu and freeze and the outer screen will go blank! Also the bluetooth never worked right the moment it came out of the box.
