I have got a no sound issue on my Global Moto G and my father's Dual Sim one after update to the latest version of stock KitKat. All are not rooted.
Suddenly, there is no sound when I have a phone call, no sound from the back speaker when play music though I changed to normal profile, no silent, no vibration. After reset, everything is back.
I am trying to disable all application switching profile automatically like Assits. Don't know it will occur again.
Did anyone get this issue?
