iPhone 7 random freezing with incoming calls

[rhiggs]

Hey. 

I helped set up an account for my friend last Tuesday. The last 3 days his iPhone 7 has been freezing at random incoming calls so that he can’t answer and has to hard reset to get the phone working again (He’s 75 and I had to show him how to do that). It’s been happening more often then not. Thoughts?

 Took the PM sim out and placed my Bell Sim (work phone) in. Phone worked no problem. 

Put back the PM Simm and I reset the network. Took a few minutes, but it looks like that exercised the Bell demons out of it. Lol. 

My guess is that the phone was trying to accept the PM call and expecting Bell at the same time. Caused it to freeze because it didn’t understand.

@rhiggsApple iPhone 7 has a hardware defect where the audio chip will desolder over time.

A quick way to diagnose it is open the voice recorder, it complains no microphone.. that's an audio IC issue.

@rhiggs Sounds like a hardware issue with the phone. Check to see if you can run diagnostics on that phone or maybe worth doing a factory reset to see if it clears up.

Maybe update IOS if not done already.  Network reset.  

If it continues, maybe try his SIM card in another phone.  To determine whether it is a hardware issue versus PM service issue.
