Lately I've seen a lot more crashes to the Apple logo on both my iPhone 5S and iPad Air 2. What's odd is that a crash on one appears to trigger a crash on the other. For example, about 15 minutes ago, my iPhone started getting sluggish while it downloaded app updates. It would freeze for up to 10 seconds while doing things. It seemed to recover, but then crashed to the Apple logo. My iPad then crashed to the logo about 20 seconds later. This is the 3rd crash on my iPhone in 2 weeks (2nd in a few days) and the second on my iPad in a few weeks. It seems to be caused by processes locking up. Usually it seems to be the Mail app, but in this case it wasn't. I had no Apple logo crashes under iOS 8.2. Anyone else noticing more Apple logo crashes in iOS 8.3?
