Hi, I updated my MI4 to version 5.10.8 then due to some problems , restarting the phone resets all, I tried to remove the cache recovery by restarting the phone but I did not have the 8 5:10:15 but the strange like thing .. when I call and when I put the speakerphone hear a rustle .. this happens when the active dual microphone , updated to the new bulid the problem remains.
