For incoming and outgoing calls, the main microphone does not work. That is, I hear the interlocutor, but he does not exist. It also does not work for voice search.
The microphone works in hands-free mode and with audio or video recording.
In what there can be a reason and how to solve this problem? Thank you!

Build number P2_Blackview_20170307 - the last official.
Re-flashing the same assembly did not fix the problem
