I have a DOOGEE DG500 running Android 4.2.2. Apart from automatic updates for installed applications, no other applications have been changed recently.
I switched my phone to the silent audio profile so that I could sleep. The next day I set the audio profile to general again, but no sound can be heard from the phone.
The phone has not been dropped or misused in any way.
I have tried turning the phone off, removing the battery for a few seconds and re-assembling everything together again but I had no luck.
How can I fix the sound?
