Firstly, I would like to give you a little backstory. I got an iPhone 13 Pro Max for repair. Firstly, it has a 3cm long "yellow burn" on the upper left side of the screen, because the phone got heat there for a short time, but everything works fine on it. The front speaker was working, but I had to replace it because it was deformated. The LiDAR sensor was not working, it does not give an error when I tested it with software, but the sensor output was nothing, it did not scan anything. So I decided to buy a programmable one to replace it. An other repairer used to replace the rear camera in the phone, so I decided to buy a Tag-On Flex to programme it as well. Also, the customer wanted me to replace the back glass, the flash, the wireless charging coil and the bluetooth antenna. I replaced them and I put the parts back together, but there are some remained issues.[br]

The first problem is with the Camera module. I did everything, the programming process went well, but the LiDAR is still not working, it has the exact same issue. I tried to programme it again, and I also checked the coneectivity a lot of time, but I couldn't solve it yet. Also the Camera Message does not dissappear, but I guess it is because of the LiDAR sensor failure.[br]

The second problem is that the Apple Pay does not work, after the repair, I can't scan a card or pay with it either(back then it was working).[br]
[br]
All the feautes working fine execpt these ones. The flash, the wireless chaging and the bluetooth is working properly, also the camera is functioning as expected, but I can see the difference in focus time and precision.[br]
[br]
What would solve these problems? Do you have any solutions? Also, is there any way to make the "yellow burn" dissapper or make it less visible? I tried to put a privacy screen protector on it, but it does not make much effect.[br]

Thanks for your help!
