How to Fix iPhone X Face ID Not Working After Screen Replacement
Duration: 45 minutes
Steps: 6 Steps
Replacing the iPhone X display assembly typically doesn't affect Face ID. However, we've had some users report that Face ID stops working after they replace the display. After some digging, we think this issue could be caused by improper handling during the repair, potentially leading to damage to flex cables or other parts. Keep things gentle and steady during the swap, and if you're still having trouble, feel free to schedule a repair.
Step 1
- If your iPhone X pops up with a message saying ‘unable to activate Face ID on this iPhone’, don’t panic! Something’s just a little off, and we’re going to sort it out.
- Trying to set up Face ID and get hit with the message 'Face ID is Not Available, try setting up Face ID later'? Not ideal, but it's not the end of the world. We’ll take care of that!
- Interestingly, some users report Face ID works after dropping the phone. But after replacing the display assembly? Well, that’s where it can go a little haywire and stop working.
- If Face ID is giving you trouble after a display assembly replacement, it could be a case of a misstep during the repair. No worries, though – this can usually be fixed easily!
Step 2
- Take a close look at the Infrared camera and dot projector module under the microscope. Everything looks solid here.
- Next up, let's check out the Flood illuminator module located on the earpiece speaker and front sensor assembly.
- Ah, there it is! The flex cable right next to the Flood illuminator module is definitely showing some damage.
Step 3
- Alright, time to carefully detach the earpiece speaker from the assembly. Be gentle, you got this!
- Next up, let's remove the ambient light sensor module flex cable. A little patience goes a long way here.
Step 4
- Flip the flex cable over and lock it back into place. Now, go ahead and remove the Flood illuminator module.
- Grab a fresh flex cable. Add a bit of Paste Flux to the bonding pad, and solder the Flood illuminator module back into place.
Step 5
- Time to reattach the ambient light sensor module flex cable. Just solder it back in place, and we're one step closer to a fully functional device!
- Next, let's get that earpiece speaker back to the flex cable and into the display assembly. Tighten everything up with screws to make sure it's secure!
Step 6
- Head over to Settings > Face ID & Passcode and tap on Reset Face ID. After that, you’ll be all set to set up your Face ID again like a pro.
