I was hopeful, Im only have two issues with IOS 8 and now IOS 8.0.2. Screen rotation sometimes gets stuck 2 a day not more, on landscape mode. If I launch another App it corrects itself. The 2nd issue is I get a alert twice or more a day, couldn't complete download, cancel or try again. After I updated to 8.0.2, those issues happen less , but still occur. These are the only issues I've had, but they are annoying. Lol
I noticed battery drain on my iPad mi I retina and my 6 plus and there is a bug on iOS 8.0 and iOS 8.0.2 that drains the battery. Stacks+backboardd is one issue that I see on my iPad mini retina and my 6 plus, also on my wife's 4S.
I know that 8.1 will fix this bug and the battery drain issue.
