Mi4 Problem With Calls

Oct 28, 2015
Hello, I have small problem with my Mi4w, so if anyone maybe can help me. I bought Mi4 two weeks ago and everything was fine for a week. Then problem occurred - whenever someone calls me (or I call someone) I can't hear the voice from the person on ear speaker, unless I turn on the loud speaker. Person on the other side can hear me in both situations without any problems. After reboot everything worked fine for a week. Then same thing happened 2 days ago. Again I rebooted the phone, but yesterday problem occurred again. Hardware test is ok (didn't tried yet when I can't hear the caller). I hope it's software related? Because after reboot everything works great. Does anyone have (or had) similar problem? Btw. I have latest dev EU rom (English language) on phone.
