iPad 2 and iOS 8.0.2 problems
If you own an iPad 2, I would suggest you avoid iOS 8.0.2. Here are a list of the problems I encountered. Where I was able to resolve it, the solution is also listed.
Hardware: iPad 2 WiFi 32 GB Model A1395 with 8.3 GB available
1) Immediately after applying 8.0.2 using iTunes on a MBP, the iTunes status showed that I was 15.4 GB over capacity. I looked at the usage in the iPad settings and showed 2.4 GB available. Digging around, I found that none of my music appeared in the Music app. I tried several reboots of both the MBP and iPad, but nothing would fix the issue. Resolution: I finally had to do an OS restore followed by a Restore from Backup to get my apps and settings back. The music I had to manually restore.
2) When opening multiple tabs in Safari, then closing one of them the tab to which I am switched back is blank. While this sounds like an irritating issue that iOS Safari has had for years, it is different now. In prior iOS versions, the tab would be blank but would immediately refresh the content when I switched to it. The automatic refresh does not work consistently now, perhaps only 40%-50% of the time. I have no solution for this.
3) App switching using a double-click on the Home button or via a four finger swipe up is very slow. I have no solution for this.
4) Safari seems extra slow. I have no solution for this.
