More or less the same here with iPhone 5.The settings app dumping to the springboard seems to be a common daily occurence for me. I don't really mind too much but it does reset the battery usage info.
The Respring to Apple logo has happened to me one time.
Yeah, come to think of it, I've started seeing those somewhat more often recently as well.Between 5-10 Safari crashes in the last ~10 days.
