Help sound issues

My non rooted lg spectrum phone won't stay on vibrate after the ics update. I switch it to vibrate and within 5 minutes the sound turns back on without me doing anything. Anyone else having this problem and does anyone know of a fix?

So do the Power+volume down reset? Do I need to backup all my apps and pull my sd card before I do it? Or will all my apps stay?
