Press and hold the Power and Volume Down keys at the same time for 10-15 seconds. Let go and the phone will restart.

Backup your whole phone and do a full reset.

this problem still exists in my phone. I think it's firmware problem because in speaker mode my phones works perfectly. but when i switch back to normal mode .. the person cant hear my voice. It's cancelling my voice. I've been experiencing this issue for last two years
