I just upgraded my phone to the Galaxy 4 the other day. It has a proximity sensor so I can wave my hand over the screen and the clock/message/call counter will appear on the screen for a few seconds. Well I just found out I can have the phone sitting on my desk and blow a big, thick cloud of vapor over the phone and it has the same effect. That's so much cooler than waving my hand or looking at the clock in the corner of my computer screen! There's no real point to this other than to say I think that's awesome.
