After installing gdr2 I have problem with sounds. When I restart a phone everything is ok for a while and after that sound just disappear. Anyone have same problem? Any advice?
I already done hard reset and few soft resets.
I did have the same...
very strange but removing and reinstalling whatsapp is the trick!
After doing that I never encountered isssues anymore.
So remove whatsapp....restart and reinstall wahtsapp...
Good luck!
