I am another customer who's Face ID magically stopped working after the 16.1 iOS update... Im on a iPhone 13 mini fyi.
This is 100% related to the software update iOS 16.1. So its a bug and hopefully Apple will fix it by next patch (currently 16.2 and the problem is still here yikes...) I have tho found a TEMPORARLY solution, and by temporarly i really mean it, it works for less than 5 min then the Face ID glitches again.. Here's the "fix/solution"
- Lock the phone and lay it down with the SCREEN SIDE(front camera) down on a flat surface.
- Press the power button to light up the sceen.
- Slightly lift/tilt up the bottom edge of the phone so u can manage to swipe upwards to unlock. (without lifting the whole phone).
- After the swipe lay it down again just like it was before. And wait 2 seconds.
- Now lift up the phone & point it towards your face and it will lock up without a problem.
IMPORTANT: The reason behind step 1, 2 & 3 is because this only works if its the FIRST attempt to scan the face/unlock... Since it only works on the first try you cant just hold the phone in your hand and do step 4&5 unfortunately. Because if u do that, Face ID will have attempted to scan a face once (& fail) & this only works on the first scan attempt. If your on step 3 & you accidently lift up the phone to high so the front cam tries to scan a face and fails(leaving you with 2nd attempt to scan a face) then u have to re-do everything from step 1… meaning > unlock the phone with passcode then procceed from step 1 and onwards again.
IMPORTANT: For some reason this only works on a FLAT horizontal SURFACE (straight horizontal angle) when ur doing step 1...
After doing these steps the Face ID will work for like 5 minutes if even that. Then it glitches again and u have to re-do the steps if u want it to work for another minute lol.
So i wouldnt call it a solution/fix just a weird interaction to unglitch the dot cam/Face ID..
For people with this same issue that resetted their Face ID in hope to fix it and are now stuck with setting up a new Face ID & only getting ”Lower/Higher your phone” or ”Face ID is not avalible right now” while doing so these steps also works for that..
tons and tons of people got this exact issue with Face ID after iOS 16, this is NOT a coincidense.. I haven't seen or heard a WORD from Apple about this issue and its been ongoing since September.. Not okay
