iPhone is automatically declining calls and the call immediately comes in again
I have an iPhone 12 Pro Max that since the internals being replaced by Apple themselves a lot of calls are automatically declining when incoming and call then immediately starts ringing again. I have checked that auto answer is off, calls on other devices is off, moved from eSIM to physical sim, Network reset has been completed and I’ve reset the phone set it up as new (not from back up) and the issues still persists. I’m struggling to find anything about this online.
iPhone 12 Pro Max, iOS 17
