When I get a notification, like an email or text, I want the phone to vibrate for like 15 seconds in like pulses of 3. It will vibrate a fair amount if the volume is on, but when I put the phone to vibrate only, the ONLY thing that vibrates is the ringer. I find this to be a general annoyance with Android I think. Anyone know a way I can customize the vibration settings for notifications (text, email, etc...) when the phone is on silent (vibrate only)?
