Now, the (dual-)core of the phone: the motherboard. LG was good for the board: almost everything is linked by connectors, easily removable!

Let's continue our dissasembly by disconnecting the four remaining ribbons:

The digitizer

The screen

The rear camera

The front camera and the proximity sensor

The antenna. Useful if the antenna was torn because it is easily replaceable!

Is it me or the phone includes a second antenna for dual-SIM models?
