[AC Question]

i have observed my micromax Q380 mobile is having some disturbances on it. first it has got a problem like no incoming call sound . secondly, there is one star symbol at the top of the screen .

I believe the star is the indication that the priority notifications setting is enabled. Press your volume up button a couple times to go back to normal notifications. This would also explain the lack of sounds.
