I was curious and flashed a stock 4.4 on my phone. turns out I missed some cm feature and I tried to flash 10.1.3. Problem occurs here. After flashing, the phone speaker or earpiece is not working. I tried searching everywhere and none of them help. Another problem is the volume control is lagging. It hangs when I try to use the volume button to adjust the ringtone volume. Wifi is stuck on "turning wifi on"... What did I do?...
seems like the system is lagging because I would not respond to my touch while the volume panel appears and haven't make the changes to the volume.
The volume control runs normally while in the lock screen...but with no sound
