Any idea why FaceID might not be working on the new screen?
I have a global/EU iPhone XS (A2097) and this is my second iFixit screen replacement. Unlike in the guide, the earpiece and sensor assembly remain connected to the logic board and are not connected to the screen at all. Last year, I purchased a replacement screen from iFixit, replaced, and everything worked fine. Because the earpiece and sensor assembly were not attached to the screen, I simply disconnected the two connectors from the old screen, connected the two connectors for the new screen and... voila! Now, however, with the new replacement screen, FaceID isn't working. However, when I reconnect the old replacement screen, FaceID works.
I've attached a link showing the inside of the iPhone in between both replacement screens. I've also highlighted the earpiece and sensor assembly which you can see is still connected to the logic board despite the screen being completely disconnected.
Any idea why FaceID might not be working on the new screen?
Is this a good question?

TLDR: my zombie twin started the repair, screwed it up (ha, ha...pentalobe pun there) and posted on iFixit. Once I discovered this, I removed his head with several well-placed spudger strikes and fixed the problem.
Thanks to all of you and my apologies for keeping this posted AFTER I had actually figured out the problem. Yes, you are both correct in that I inexplicably left the pentalobe screws in. Despite having repaired countless iPads and iPhones...yeah...I really can't begin to explain how I neglected to remove them, missed the problem, took pictures, did an extensive write-up, and then posted on iFixit.
In fact, I didn't realize the problem until my wife looked at the screens and remarked that they didn't appear to be the same size (hello, frame). Unfortunately, she didn't do this until after I had already posted here. {sigh}...
Again, as always with the iFixit community, thanks for your helpful replies.
