iphine 13 pro sound & mic issue

I have new iPhone 13 Pro.. sometimes the caller couldnt hear me suddenly, problem remains that when I go to maintenance it works normal in front of them 😅 and once I go back the issue appears again!

They always said one of these 4 solutions:

1. A network issue (it is not a network because i make calls from different locations and nothing new the issue exites).

2. Close the noise cancellation (which is locked).

3. I have a problem with my data backup, and the photos and files that I download have a problem for a long time, especially since they are old things, and when I upgraded the mobile, it appeared and the mic came out (and I didn’t say anything because I originally ran the mobile without any backup at all, only a slide and without phone numbers, and the same problem happened) .

4. I'm doing a software update (and the software always up to date).

The problem still exists.

-Noticeable

The authorizer does not do anything except that it detects the hardware and reports that everything is in order and that the phone does not need to be returned or replaced.
