I got an AT&T S4 about 6 mo. ago. Within the last week it has been randomly turning off sound, and crashing when making phone calls.
I'll pull out the phone and try to open a youtube video, and then realize it's making no sound. I then reset the phone and the sound starts working again. I just tried doing that and the sound remained off even after the restart. I then tried to access >settings >my device >Volume, and it crashed. I tried again to access >volume and it works (though there's still no sound.)
Around the same time (about a week ago) I noticed that when I made phone calls and put the phone up to my ear it didn't make the regular sound (assuming it just indicates that it's making the call) and then the phone froze completely. The recipient of the phone call couldn't hear me and, after pressing the lock button, it returned me to the lock screen with the green phone icon in the corner. I *could* access the restart/power off/etc.. menu but nothing happened when I pushed the buttons. The last time this happened I had to remove the back plate and take out the battery. I just tried to call the S4 and upon answering I received no sound and could send no sound to the other phone. Then there was a pop-up on the phone: "Activity Phone isn't responding. Do you want to close it?" I hit ok it returned me to the home screen.
It's been acting a little slowly and (what appears to be) hanging every now and then. Any help would be much appreciated. I can post more information if you need it. I have android 4.2.2
