my phone has recently just stopped vibration all together. Ive tried multiple vibration tests and gone through ever setting on my phone and still nothing. Ive read up on heptic feedback and attempted to find that under sound as well as power saving mode, but there is no option. its motherboard was replaced recently as it was fried but the vibration worked after that and has all of a sudden just stopped now. i don't know whats going on. i have jelly beans v 4.1.2
