Microphone faulty

I have issues with the microphone being crackly and then cutting out so people can’t hear me. Not all the time, but most of the time. Can temporarily help by going on to speaker but then it often cuts out completely - bit like it got fed up! It works on video recording but not video calling. Tried help but VERY slow and now can’t rely on phone for important calls.

oh… and the card is now not registering.

You have three three microphones in total, this could explain the difference between camera use-cases and calls. Please dial *#*#2886#*#* and choose Audio. Skip the first tests with PASS if the phone plays a sound. More relevant to you are the test named mic x to xxx. Just blow at the little holes in these spots and check if you get a consistent sound played back.

Microphone 1: lower side, left
Microphone 2: upper side, right
Microphone 3: left side in the middle


Treid all that and work perfectly!
