hi community, lately, occasionally I would not be able to hear anything coming out of my phone, The volume would get muted, and if I call anybody, i cant hear anything. i know the FM transmitter is OFF, and the phone is in Normal mode. Even if I un-mute the phone, I still cant hear anything. I have tried restarting, and that still doesnt fix it. The only way I am able to get it back to normal is by taking the battery out and putting it back in. Any suggestions? Thanks
