G1525361714748 , via OnePlus 9R , Oct 23, 2021 : My phone's mic has been dysfunctional for a while now. A lot of people have complained that while I talk on speakerphone, either I'm inaudible or my voice is constantly breaking. As a result, I cannot have video calls with anyone. I have restarted it, that seemed to solve the problem for a little while but it's back again after a few hours. Cleaned the cached data, have enough memory, no network issues. Tried most tricks but still doesn't seem to be working properly while I'm on speaker. Kindly help if someone can.
