Anders_ASUSHmm okay, will try to update and see if that fixes it, thanks.
You can't adjust your microphone level. It's automatic.
I haven't heard anyone else mentioning about this. You could test all the reset options in settings -> system one by one to see if it solves your issue. Maybe it will be solved next time you upgrade your FW. I recommend you to download it as soon as it's available on our homepage instead of doing a normal FOTA. In same rare cases, it can solve weird issues that others don't have.
