Notifications problem - really makes me mad

I received a notification from the system update that I can upgrade to 4.5.7I
I updated the device and after installation I get notification every time I use the phone , but there’s no notification, it always makes notification sound but again there is nothing. It’s really annoying, it also makes vibration when I in vibration mode A-L-L THE ****ING TIME !
I tried to reboot the phone and it did not help, what can I do?

I’m having exactly the same issue and its driving me mad! If anyone had any ideas please share!
