I and many more people have the same problem with mic on phone, only upper mic is working in 3rd party apps and on loudspeaker calls, it works just fine in stock recorder app, so problem is purely software, yet for more than a year nothing were done to fix this problem. Do u plan to finally do something about this problem? This is my first asus phone and im very dissatisfied, i never gonna buy your products in future and advice all my friends to do so.
