I set the ring type to 'vibrate + ring' yesterday. Now, for every incoming call it only vibrates and doesn't ring after sometime. When I tried to reset the ring type to 'ringing' it says OK but doesn't actually set it to ringing. This is very annoying as most of the incoming calls are getting missed due to no ring. Anyone else has faced this problem before and was able to solve it? Is it possible to reset the mobile somehow and bring it back to 'ringing' mode? Any help appreciated.
