My microphone 1 doesn't seem to be working properly. I'm pretty sure it didn't work from the beginning, as I couldn't get "OK google" to work on 20180823 (the original firmware). I did not upgrade at the time because I was waiting for a fix for the camera and security-lock issues. I thought may "OK google" wasn't working because I did not log in with an account yet.
However, after updating to 20180914, the microphone still didn't work. Voice recorder records my voice fine, but I cannot be heard when making a call. After updating to 20180920, the microphone still doesn't work. I tested both microphones with the "*#*#33#*#*" single-test menu:
Microphone 1: FAIL
Microphone 2: PASS
Now I have checked around a bit, and I found that in 20180830, the EngineerMode code (*#*#3646633#*#*) works. I believe that initially the microphone also did not work in 20180830, but I'm not 100% sure that I tested it with the single-test on this version before making changes. I went into hardware testing > audio > volume > voice, and changed the "SIDETONE GAIN" from 0 to 164, the same value as the normal gain value. After this, microphone 1 worked. I then tried setting the sidetone gain back to 0, and the microphone still worked. Happy, I proceeded to upgrade again to 20180920. However, I found that now the microphone again wasn't working anymore in the single test. I downgraded again to 20180830, and now the microphone works again, without having to set the sidetone.
So my situation now seems to be:
20180830: microphone works
20180920: microphone does not work.
Could someone please help me? |
