Why can't i hear the ringing sound or can't even find that some one is calling?

i installed 10.3.1.1151 and the volume is full.
I even changed the ringtones also.
but there is no use.
Actually the problem is - i cannot find the calling screen or even i can't hear the ringtone when someone is calling me.
I did security swipe and even installed the OS once again. But no use, the same problem is continuing.
Should i RELOAD the old OS and wait till the official release?

Sounds like you should go back to official and wait.

nope. Now it's fine.
i just connected it to the PC did reload with connecting to the internet.
Now it's good

I think that took you back to your official.
