my phone has been working perfectly fine since ive had it. last night and this morning the sound for my alarm clock never went off even though the sound was on Loud. I just thought it might be a rare thing and ignored it. today ive been using my phone for phone calls and was able to hear and talk to the other person on the phone and as of now i dont hear a dial tone, a voice, or anything. i have tried to reboot by doing a battery pull, and using the app called "quick pull" many times.
