Introduzione
Though it would be considerably difficult to damage the keypad, stranger things have happened. Also, after long term use, the keys themselves may become dirty and start to stick when being pressed. In order to solve both of these issues, you may need to open up the phone and either replace the keypad (in the case of damage) or to simply clean it off and clean the inside of the case to prevent further sticking. This guide takes you through the process of getting to the keypad.
