I don't have a gaming profile in my Rog 2 mobile.
And since a month my microphone isn't working.
I've factory resettled my mobile but still the problem persists.
Could anyone be of any guide for me?
Your microphone component might have got damaged, did your device got in contact of any liquid? Go to calculator and type. .12345+=
And check if your microphones are working or not.
Only a service center will be able to help you if a factory reset didn't fix your issue. I know you're on lock down but please contact them once it has ended
