[AC Question]

I noticed just yesterday, that my phone will not vibrate for notifications anymore...it shows that it is selected still, but wont actually vibrate?! I really need this feature for while I am at work...so I know if I get a call or text, without having to have the ringer go off! Is it possible my phone's just broken?

Welcome to Android Central! Which phone? Does it vibrate for anything else? Have you tried rebooting? You could also try Safe Mode, which temporarily disables all 3rd party apps. On most Android devices, while powered on, press and hold Power until the Power Off menu appears. Press and hold the Power Off selection until the Safe Mode prompt appears. Tap OK.

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
