My phone randomly vibrates
I bought a Smsung galaxy Young a week ago ( not second hand, all new ) and it vibrates randomly!
I have tried to turn off the vibration but it still vibrates for some reason, I have checked so there are nothing running in the background that makes it vibrate.
When it starts to vibrate it at first just "buzz" a little for a while, then it vibrates, starts to buzz, vibrates, buzz etc, I have to press any button on it to make it stop.
I have go launcher and sms pro installed and a few other apps, but would any of those cause it?
