The major problem keypad occurs:

Sometimes the key pad some button will not work proplery it will work only if it pressed hardly. Actually keypad should be used softely this hard touch key pad will make the circuit board to get spoiled and the pathway of the circuit board will also get squashes due to some reasons. The major problems what key pads occurs:

1. Some of the keypad button did not work: To solve this problem remove the panel from the body of the cell phone and clean the key pad gently with the cloth and the connection of the keypad to the circuit board should be also cleaned gently by using petrol or white petrol neatly. This kind of things will itself make the key pad to work smoothly.

2. The key pad is gud but some buttons not working: To solve this problems take the panel from the cell phone and each and every button faces in the circuit board and each and every buttons will have a connectivity to the other buttons and finally this connectivity goes to the main spares in the circuit board. So, Check whether the main parts of the body receives voltage and if it receives the voltage whether it supplies the voltage to the connectivity of the button places. Then do the further steps to work it properly.
