Random vibration

Hello,
My S4 mini vibrates randomly every now and then. Without any notification. I am sure its not smart alert.
This happens only when it is connected to internet.
Any solutions?
Thanks,
Mit

Welcome to Android Central.

That sounds like a software bug, but I don't know how you'd fix it. A Cache Partition wipe may help.

Also, it may be worth trying Safe Mode, which will test whether some third-party app is causing the trouble.
