iPhone 7, iOS 15.7.5 . Microphone is inaccessible, and none of the apps can use it.
Very strange, at one day, I could no longer receive calls with any and every app, could not call, cannot record Audio messages in any app, cannot use Voice Memos app.
When I open Whatsapp and press the "Record Voice Message" button, iPhone vibrates for a moment, as if it "denied" my use of this feature. Same thing happens with Voice Memos, when I press the Red Button to record, nothing happens as if I did not press the button.
When I use "Phone" app to make normal calls, is says "calling [name]", I cannot hear another person, and person cannot hear me, and I cannot press the "Speaker" button during call.
At the same time, when I receive a message or a call, I can hear Notification sound, and when I use apps like youtube, I can hear video or music.
I did not change settings, did not drop iPhone on the ground or in the water.
I have already tried:
1) Extract and Insert SIM card
2) Reset Network Settings
3) Reset All Settings (NOT Erase)
4) Reboot iPhone
5) Re-install iPhone using Full ERASE option.
6) Turned Airplane Mode ON and OFF several times.
7) Toggled ON and OFF many settings (before ERASE or RESET SETTINGS)
Any help would be appreciated, and there are no working solutions from the Internet that I could find.
