In the past, customers have glued there battery back into the device. This may keep it extremely secure, but all batteries need room for expansion, otherwise they are prone explosions.



The sensory array is transferred to the new assembly, ahead of the motherboard being refitted.

Before the repair can continue, a screen test must be performed. The test includes dragging an app around the screen and checking all letters on a keypad to identify any dead pixels or blemishes in the screen.


Now the tests have been completed, the upper antenna/wireless charging will be secured back into place using the 14 screws used in the previous assembly.
