Hallo, I have some issues with my bluetooth headset and i don't know what to do... The problem comes definitely from the Mi2S as my friend's Mi2S has EXACTLY the same issue whereas every other android phone i tested works perfectly. My Bluetooth Handsfree is the Sony SBH50. I can hear music with no problem... I can hear people's voice perfect! BUT they don't hear me good enough... It sometimes makes some interruptions of my voice they tell me... I can hear them fluently but they don't understand a word from me! And this does happen often. I tried other MIUI version... But nothing... Erased Dalvik, cache... nothing... Tried the same bluetooth Headset from a friend... Again the same problem, so its 100% our phone's problem... Please... Any idea of what can be wrong?? Maybe kernel or smthg?? Till now the phone worked like a charm for me, but since i bought the bluetooth headset i found this problem and it drives me mad after each phone call... Btw, i don't want to change the headset, as it has a display with caller ID and its very usefull (except if you know any other headset with such a display). Please help me! Thank you!!
