Kyocera Rio E3100 soft resetResetting the phone
If the screen seems frozen and the keypad does not respond to keypresses, reset the phone by completing the following steps:
1. Remove the battery cover.
2. Remove and replace the battery.
Press ##786. Be careful when you reset as your phone will be completely reset. Once it reboots you will have to reprogram your 10 digit phone number into the phone. This can be done by dialing ##000000# and then choosing the edit mode and entering your 10 digit number in both fields.
If the problem persists, return the phone to the dealer for service.
