I keep my phone on silent/vibrate 100% of the time. I only allow text messages, Google Voice, and FB message notifications through. All of which should be ion vibrate. Texts and Gvoice are fine but I can't get FB messenger to vibrate. ALSO, every time I get a notification that I don't want coming through I get a notification that says "silent notification." What the flip is the point of having silent notifications if I'm just going to get anonymous notifications every time instead. Now it's worse because I have to go through all my apps to figure out what the notification was for.How do I stop these things from happening!?! ???
