I dropped my iPhone 4 for the first time yesterday.
I was on the phone going out to my car and somehow it flew out of my hand and I even managed to scratch myself in the forehead some how.
So it landed face-up on the concrete - about a 5-foot drop.
I have it in a hard+silicone case, similar to an Otterbox. The point of impact appears to be the front bottom left corner, because the plastic part of the case is scuffed up/scratched there.
Upon inspecting my phone out of the case, there are no signs of damage. It's been fine all of today but earlier, about an hour ago, it did a short vibrate twice in about 10 minutes but I had no notifications. That made me worry that something got messed up.
Is it likely that was nothing, and my phone is fine?
