iOS 9 Update: 10 Reasons to Install ASAP

If You Have iOS 8 Problems

If you are having iOS 8 problems, on iOS 8.4.1 or otherwise, and you can't fix them yourself, you might want to think about installing the iOS 9 update right when it arrives. 

The iOS 9 change log will include fixes for lingering iOS 8 problems (and probably Apple Music problems as well). We also expect the iOS 9 update to iron out issues that aren't listed on its change log. This is fairly common. 

There's no guarantee it will alleviate your issues but there's a chance and it's that chance that makes the iOS 9 update an update worthy of consideration.
