Problem after upgrade to ICS- Phone turns to vibrator mode (without ring) automatically when someone call me.

[#1]

I have recenlty upgraded my neo to ICS.  Since then, when I get a call, (even missed call) it turns my phone to vibrator mode automatically. So whenever I get calls, I have to turn on the ring manually. Otherwise I would miss the later calls. Please help.

It will erase all data on phone, backup necessary

[[[suggestion..... format your sd card before installing ICS ( for clear installation)]]]
