I have been searching for an answer about this on the iPhone 13 series. When these phones were first released, screen replacement would disable Face I.D. unless an IC chip on the back of the display assembly was transferred. This has since been changed, but I do not know about the proximity sensor flex. No tutorials or guides that I have found have mentioned anything about transferring the proximity sensor flex cable, so that leads me to believe that it's not necessary anymore as long as you have another one.

So my question is this: Does the proximity sensor flex cable need to be transferred to retain Face I.D. functionality as it has in past generations, or is it no longer linked in the same way that it used to be?

My Apple Pay has not worked at all. No card machine will recognise my device is there, it worked once since this happened, but not again.

An airtag type device used called 'squid' for tracking loyalty payments which also uses NFC (I assume) also would not recognise the phone. This makes me think there is a hardware issue with something, and not an Apple Pay problem. I deleted and put all my cards back on but the different pay terminals, and this squid tap loyalty thing still didn’t recognise my phone.

So, after seeing somethings about possibly loose NFC antenna plate, or something like that, does anyone have any insight?

Or links to a guide i might use to open up the back of the iPhone, locate the plate and NFC antenna, and check if there is anything out of place from a drop potentially?

It is especially visible when the screen is off.

What would be a cause of this?

Below a photo of the screen when it's off:

NFC only works on iPhone 13 when the display is lifted from housing. Once the top portion of the display is clipped in, NFC no longer functions! Like the display is a barrier to the signal?

History: the phone has had a housing replacement which includes wireless charging flex. I have tried swapping genuine NFC flex (near camera) same issue. Not a motherboard issue as installed it into complete phone and works fine. To me this seems like a housing issue? Can a housing be faulty? And other things it can be? I have scratches the metal connections where the flex is attached to the housing for better conductivity. Still nothing.

The original housing has spot welded metal extensions which touch with the metal part on the NFC flex, on the replacement this isn't present.

I have tried every online solution that I could find: put it in airplane mode and restart, take it out of case, reset network settings, even those third party repair drivers apps. Nothing has worked. So today I broke and finally opened my phone for the first time and replaced both antenna and it STILL doesn't work. I have no idea what to do, I've factory reset it, I've done everything I can find, but nothing works.

Does anyone have any clue what this could be caused by?!?!?!

After the issue appeared, I contacted Apple Support, who advised me to perform a hard reset. When that didn’t help, I took the device to my local Apple Authorized Service Provider (AASP). They ran diagnostic tests, including multiple reboots, but the horizontal lines persisted. Their diagnosis: a faulty display assembly. Unfortunately, since my device was out of warranty, the repair quote was an outrageous $456.57 USD!

I reached out to Apple again, expressing concerns over the excessive cost, but was told there was nothing they could do and that I should consider buying a new phone.

After looking into this issue further, I found numerous reports from other users experiencing the exact same problem:

• Horizontal rainbow lines in iphone 13 - Apple Community
• rainbow screen on iphone 13 - Apple Community
• iphone 13 - The screen showing horizontal… - Apple Community
• Sudden rainbow screen on iPhone 13 mini a… - Apple Community
• Why does my iPhone 13 mini have verticle … - Apple Community
• Flickering screen issue on iPhone 13. - Apple Community
• Display issues with recent upgrade to ios… - Apple Community
• iPhone 13 Mini display issue - Horizontal… - Apple Community
• Rainbow lines - Apple Community

These are just a few examples — there are many more similar cases.

I still have much older iPhone XR units that have never had any screen issues to this day. Given how widespread this problem appears to be, is there any way to push Apple to acknowledge this as a manufacturing defect rather than an expensive out-of-warranty repair?

Any advice or shared experiences would be greatly appreciated!
