Samsung Galaxy R Motherboard Replacement

はじめに

The motherboard is the main computer of the phone responsible for all the computing power. Motherboards will not need to be replaced unless the phone is having serious issues with receiving or transmitting signal, data, or other essential functions. The motherboard contains all the other smaller parts used in more specific functions. In order to access the speaker and rear-facing camera, the motherboard will need to be lifted. To lift the motherboard, small screws will need to be removed before using the fingers to carefully pull up the multiple pieces of the board.
