Don't even talk to me about iOS 11... Upgraded from a (somewhat sluggish, but usable) 5S on iOS 10, to a new iPhone 8 on iOS 11... The snappiness in apps is all there (which is what I wanted), but man the bugs! One of my current gripes is that I can only be 80% sure a photo I'm taking will save to camera-roll... I thought I'd lost all of my videos from Christmas Day morning until they spontaneously appeared 10 minutes later.

Trying to post to Instagram Stories is another fun game that tends to fail 50% of the time.
