Same here, i have change roms so many times but after some days i can hear the others but they cant hear me.
so bad for an expensive mobile like this.
i want to send it out of the windows
i download a mic test, and mic is working ...
I don't like to use another app to send an sms with 160 characters :( always 3rd apps have probs.
At WIUI they fixed it and you can send sms with 160 characters when type Unicode. At miui still not fixed this issue :(
