This took longer than expected due to the logic board removal, but wasn’t too difficult and everything went to plan.
Note that you need to be REALLY careful with the ZIF connector latches like on the battery board and logic board, they are very fragile and I had to re-attach the latch for one of them.
It likely works by measuring the surface area of the finger placed on the screen. When you press harder to activate the virtual button your finger will create a larger surface area on the screen which can be measured as more force being applied.
