Samsung SGH-A137 Keypad Replacement

はじめに

Overuse of the texting/emailing feature can wear out the keypad and even damage it depending on the amount of pressure applied. This process is still considered moderately difficult, but with patience, can be completed with great results.

Remember that you are working with sensitive electronic pieces so don't rush through the steps and pay particular attention to step 4. To much pressure or going to fast can cause the small plastic clips to break off when removing the back casing, and that will prevent a tight seal when you reassemble the phone.
