No, I dont receive messages or notificaions or something that. Like i said, i havent installed any apps and internet is turned off.

Just got bv5000 and its vibrates randomly during call. Thats not notifications because i dont have any apps and internet is turned off. I turned off vibrate in keyboard settings and sound settings but still vibrates randomly while calling.
