はじめに

This guide shows how to remove and replace the fingerprint scanner/home button for the OnePlus 3. This requires removing the daughterboard. The hardest part of the guide is getting the frame clips free.

Some guide images will show the battery and an interconnect flex cable already removed from the phone. You do not need to remove these for the fingerprint scanner procedure.

There is a high risk of damaging the display panel if this opening procedure is improperly followed.
The following three steps show how to pry the rear case from the plastic frame. Read through the steps first before attempting the procedure.
There are two different seams between the screen and the body of the phone:
Display panel seam: This seam is part of the display assembly. Do not pry at this seam, or you will separate and damage the display panel.
Frame seam: This is where the plastic frame meets the back cover. It is recessed into the back cover. Only pry at this seam.
There are fourteen clips that hold the frame against the rear case. Be aware of their location as you pry the back cover off in the following steps.

As you work, try not to accidentally power on the phone. If you do, turn the phone off before resuming disassembly.
Place a suction cup near the bottom edge of the display.
Pull on the suction cup with strong steady force.
Press the edge of an opening tool straight into the frame seam near the suction cup until the edge wedges between the plastic frame and the back cover's lip.
Due to tight tolerances, this will take substantial force. Using a new opening tool with an unmarred edge will help with this step.
Do not use metal tools, as they will most likely crack the screen.
