do not try to peel the button tape off the digitizer at this stage. There is a shortcut that will give you a lot of space for further work

My matrix is broken, I don't care about it. If yours works and you are not going to replace it - do not touch the display surface (black). Fingerprints are very difficult to remove. alternatively, you can use nitrile protective gloves (like me)

the shortcut I'm talking about is disconnecting the entire assembly. To do this, disconnect the battery voltage and remove the matrix and digitizer with the Touch.ID button tape

with red circles I mark the screws fixing the matrix
