Except that when the phone is unlocked (for e.g. maps) notifications still flicker as they happen, sometimes obstructing the top where Google Maps puts the street name and lane information.
...and I don't know about iOS, but I've had this happen at the very worst of times on Android. I've need to click on a dialog in Google Maps to accept a route change, and just then a pop-over dialog appeared that I accidentally clicked. Now the routing is backgrounded and you have some other app open.
