Samsung Galaxy Note 2 not ringing + strange sound problems

[aurimask]

Hello,

I have a problem with my phone. It is not ringing randomly when Sound is turned ON. For example if I try to do incoming call to my phone it might not ring two times and ring the third time. Some kind of strange behaviour. Also sometimes I notice that Sound turns off automatically. I have android 4.1.2. It is all original, not rooted etc.

Any thoughts what to do ?
