Introduction
If the keypad of your Motorola V190 cellular phone is not responding correctly, if the buttons stick, or if your keypad is missing a button, follow this guide to replace the keypad. The keypad uses the motherboard, allowing you to send and receive calls, navigate the phone, and send text messages.
Check for any dirt on the keypad or motherboard while the keypad is removed. Use a compressed air canister to remove any dirt.
