i have found iOS 9 to be by far the slowest, clunkiest and most error prone OS update of any. I am running it on a 6+ from a new install, and I've never been so disappointed with an operating system, it's totally slowed my entire phone down when Apple were advertising that it would be all about stability and reliability! What's worse is Apple Music. Eddy cue and all this beats $h1t have ruined what was a great, stable music app. The interface is so confusing, it's error prone, and Apple Music stuffs up so often. The most annoying of this is the fact that whenever I go to make music available offline and essentially save it to my phone, the next day it has been deleted off my phone again. And it keeps doing this no matter how many times I keep saving it, the next day it's gone and I have to download again. Getting over sub par experiences like these with the price Apple is now charging their Aussie customers.
