Many things are broken on iOS. Apple, please get your shit together.
- Random invisible touches and phone calls - BUggy Glass UI - Stupid battery management ..to say the least.
I've seen soooo many rendering errors in Safari. And bugged-out keyboard + inputs (input touch location offset from its visible location on the page after the keyboard opens—a real problem if you're trying to paste). Never ever seen it 1/10 this buggy after any prior release, and I've been on iOS since... 5, I think? And did some development work on the platform as early as version 3 or 4.
That's in addition to so many dropped frames in the animations that I disabled as many as I could because it was driving me crazy, and to a bunch of word-based buttons becoming confusing icons. I think this has topped 7 for my least-favorite iOS release, and the gap widens by the day. It's terrible.
[EDIT] What it most reminds me of (I was on early Android and have done even more development work on Android over the years than I have for iOS) is Android. The jank, the pile of little confusing UI choices that all add up into an overall off-putting experience. The uncertainty what kind of bad thing might happen when you touch anything. Feels like an above-average 3rd party Android skin, like from Samsung or someone (so, pretty bad). The stuttering animations. No other iOS release has ever felt like Android to me.
I bought an iPhone 4S way back when because I wanted a dead-simple UI for my mom.
Now she's on an iPhone SE (3rd gen), and the UI is a complete shitshow.
F you Apple.
(She also does not want a newer (aka larger) iPhone because they will not fit in her woman's jeans which notoriously have small pockets. Another "F you" from Apple to the consumers.)
No one's getting promoted for a bug fix.
