Hello,
About a week ago, I updated my phone to Oreo 8.0.0 and now my lower Microphone is not working for phone calls. It works for other applications but not the phone application. Phone call works fine while in Speaker Mode. I have tested the lower microphone while in speaker and it works then.
Things I have tried:
1. Turned off HD calling (Did not work)
2. Turned off WiFi-Calling (Did not work)
3. Tried in Safe Mode (Did not work)
4. Cleared Microphone hole at the bottom of any debris (Did not work)
5. Factory Reset (Did not work)
6. Downloaded other "phone" applications. (Did not work)
Anyone know what I can do?
