iOS 8 on my iPhone 6. On iOS 7 (and basically all previous software) by default, my email vibration would be a quick vibrate (the vibrate is actually called "quick", while my text message, by default, would be a double vibrate (called "note"). Even with those settings however, emails come in with a double vibrate. I can't tell the different between an email and a text message without looking at the screen. Anyone else having this problem?
