Hi, I've been having issues with MIUI. In many apps (Viber, Line), the other end cannot hear me. I can hear them fine. In Viber, usually they can hear me for about 2 seconds, then it stops. In Line, they get no sound at all. Any help would be really appreciated. I've already wiped my phone twice. And i really need this working. Thanks in advance. Edit: Here are the details. I have a MI3W running the lastest weekly of Miui. But the issue was present before.
