Update: I disconnected the earpiece part of Face-ID and run the phone without it everything else works fine now. I would probably try replacing that part to regain speaker functionality. One day my iPhone X started to have a lot of issues at once: Boot-loop if battery is empty, with a new battery I got it to boot and backed up my data but there are other issuesLightning port doesn’t work most of the time and even when it shows charging, it doesn’t really charge. A wireless charger works but very slowly.iPhone reboots randomly sometimes after only 3 minutes and sometimes after a few hours.Face-ID doesn’t work after some digging I found out the proximity sensor doesn’t work.Taptic engine doesn’t work, could this be due to a faulty lightning connector assembly?Cellular doesn’t workThe first panic-full log says: “AOP NMI FIQ - pc=0x0106bb9a - rtk_ep_work(0) - watchdog timeout: No response in over 20 sec.“All other logs say: “sleep/wake hang detected“ From my understanding, the first crash and Face-ID issues could be due to a faulty earpiece flex cable and the other reboots as well as lightning port and taptic engine issues could be due to a faulty lightning connector assembly. However I still have no explanation for why cellular doesn’t work. Finally is it possible that 2 different flex cables fail at once? Is a fault in the logic board more likely?

Faulty Front Camera/Speaker Assembly. I’m not exactly sure why it happens but when something goes wrong with the earpiece flex on some iPhones, it will trigger a chain reaction that prevents most of the basic functions of the device. This could be due to some damage to a chip on the flex which in turn is causing power issues and components aren’t getting the power they need to operate correctly. Usually replacing this flex cable will resolve the issue even if it means disabling FaceID permanently.
