Don't like the way a message pops up, before I had it on alerts so message pops up in the middle of screen now it will only appear from the top of the screen
Been there, done that - on an iPhone 6 / 64. 1.1GB upgrade to iOS 10 - "...our biggest upgrade of iOS yet..."
Also updated a half dozen apps once that done and my Carrier took the opportunity to update, too.
Snoresville so far.
