[Q] automatic silent when have incoming call
hi all, I found my m7 quite frequently turn to silent or just have ringtone for first second and then suddenly become silent when have incoming call. I found this problem since upgrade to sense 6. It may due to touching of the back button make it become silent during ringing or flip to silent function. Is there any user have this problem and any suggestion? It is very annoying and make me have quite a lot miss call...
