Completed the guide but my screen is not flush with the body any more. But it was no problem putting it in. TouchID etc. are working fine, it is more in the middle part where the screen has a noticable height (bump). I have the impression it is higher than the original part (the eustore.ifixit.com front cover). But happy that the display works!
My replacement part had a clear plastic that you need to remove so the microphone will stick. It is very thin so I pulled out the whole rubber part a few times before being able just to remove the clear plastic that shields the glue (part bought from ifixit.com)
