@l3enQ Have you checked if the same occurs in safe mode? Does anything else happen?

@alexdon I did not try that, because it happens very randomly and I can't wait that long time to check if it will be happened or not!

It might be a 3rd party involved. Does anything else happen besides vibrating?

It might be 3rd party apps, but How do I can find which app cause this?

no, there is nothing except vibration

but sometimes a notification with icon of white square comes whitout any sound or vibration. and dissapears in no time!
this is absolutely a 3rd party app. but i can't find it

is there any log for notifications or system events in android? like event log in microsoft windows for PC!

You could go to google play and check what you have installed lately, paying attention to the type of apps you find there (task killers, antivirus, battery savers, launchers etc).
