This is likely the Baseband PMU becoming disconnected or the Audio IC. This has been labeled “Loop Disease“ and is very similar to the “Touch Disease“ issue that was on the iPhone 6 & 6+. I am a soldering specialist and I have been seeing this a ton! If you have never micro soldered before I would not start with this one. However, a re-flow may be a temporary solution but you have to be very careful with temperature as the reverse side of the board holds the baseband ic which is under-filled.
