So i have my mp3 ringtones in the correct folder for my phone, but once in a while, i will lose all sounds coming out of my phone. Like, one minute itll work perfectly fine, and then the next, nothing, i get no sound for calls, sms, IMs, etc. are you others getting this issue as well? ive also encountered : my phone overheats with light browsing my battery barely lasts 10 hours with light usage my screen auto-highlights icons on its own can anyone suggest anything for these issues? should i go back and exchange the phone?
