Okay, first off, Face ID. You'll be transferring the earpiece speaker assembly from the old screen to the replacement; that's the part that's related to the Face ID system. Assuming you don't break anything during the transfer, there's no reason Face ID won't continue to work properly. Next, True Tone. Not an expert, but my phone had the same problem and I’m pretty sure since the LCD is still attached to the phone, all you need to do is apply some sort of adhesive or glue to reattach the digitizer and lcd. Just make sure the phone is off before hand. Pale_Cryptographer82 • 2 yr. ago. I was able to use superglue & it worked. If you are sure your iPhone supports Face ID and your iPhone Face ID stops working, you need to make sure that you are using the latest iOS version on your device. That is, you need to check for updates and update iOS if necessary. Update your iPhone, iPad, or iPod touch. Fix 3: Check Your Face ID Settings Pry open the glass cover with a blade. We can see that there are many holes on the flood illuminator that are arranged in a matrix of 11x11. The chip is connected to the circuit board with the help of gold wires.

I did get a replacement from a third party repair shop, it is a good oled but true tone does not work. I just read that if the phone is jailbroken before the screen repair and rootfs is restored, face id wont work anymore. i have 2 questions: A week ago, iFixit reported that third party screen repairs on the recently launched iPhone 13 will make Face ID ineffective. This is due to the inclusion of a tiny control chip in the flex cable linking the phone's screens, which connects each display to its own motherboard. That means, non-Apple repair stores or shops will have to desolder Hello guys, i found a really good deal on Iphone 11 Pro (250€). Phone had screen replaced recently, Front and Rear cameras not working. What i did: I restarted the Phone. I have opened the Phone to check if all connectors are in place and cables are not damaged, couldn't see the damage on them, Inserted them back into place, but still not iPhone 13 Pro Max, same problem, here's what fixed mine, it may or may not work for you. Problem: Face ID randomly stopped working a few weeks into using IOS 16 After resetting Face ID, it would not set up again Would not progress past the 'position your face' step, kept saying face out of frame or move lower/higher My Fix: Updated to IOS 16.2 L81Ro.
