I'm not sure when this started happening or if it ever even worked, but my vibrate notifications do not work for text messages or email (i'm using K-9). I've gone through EVERY possible setting, in the messaging app, in K-9, and the standard phone settings, to ensure that Vibrate Notification is indeed on, and yet it does not work. It doesn't matter if my phone is on Vibrate Mode, Silent Mode, or Normal Mode, no vibration notifications. I've tried restarting the phone, nothing works. My Haptic Feedback works perfectly. Can anyone help please?
