After a week with it, I simply just can't...
1. iOS 11 does indeed run better and smoother than iOS 10 for me. No question. Performance is solid. But interface bugs are everywhere.
2. Swipe left on lock screen, notification center, or the home screen and you see the exact same screen, with a search field and some widgets. Why? Is it so important that widgets and a search field must be shown everywhere?
3. Swipe down to access "notification center" (oh wait, they're calling it the "shade" now, huh?) and swipe right, you get access to the camera. Why? There's also a camera icon/button in the Control Center, which now takes up the entirety of the screen. I don't use these shortcuts except for the flashlight so over half of my screen is blank space. Horrible design decisions. Also, someone at Apple seems obsessed with making sure the camera is always accessible. Why? If that's the case, why not dedicate some shortcut key combo to it? Why make us see the camera every other turn on the OS?
4. 2 and 3 are arguably not "bugs," so okay, I'm probably ranting. But... use the same wallpaper for lockscreen and homescreen, and you'll see "bugs." Unlocking or pulling the "notification center" down causes this weird "blur and then no blur" effect to roll on the screen. The transition used to be much more seamless on iOS 10 and prior iOS versions. But hey, let's say that's by design. I've gotten weird animations where I go into my home screen and half of the screen is blurred but the top half is not. And it just got stuck that way until I lock/unlock the device again. The way iOS 11 is "designed" now makes the lock screen and notification center too "connected" to each other and far too disconnected to the rest of the UI.
5. No "Clear All" button for notifications so now I gotta make sure nothing but the essential notifications are enabled. But hey, even when I tap on those notifications to go to the app in question, those notifications don't clear. At all. So even after responding to the notifications, I still have to clear them all manually. iOS 10 wasn't like this. But hey, at least there's the "X" button in the upper right corner, right? Yeah, if it's WORKING, which IT DOES NOT! Sometimes if the notifications are from today, the button won't work at all. Be it on the lock screen or not. I have to manually clear every single notification manually by long swiping them. Short swipes cause this "Open/Clear" menu to open. Again, annoying behavior and a major waste of time. At this point, I'm highly considering not enabling notifications at all, but hey, the simple solution is...
6. I'm swiping everything from my phone to do a full install of iOS 10.3.3 again, where everything used to WORK. iOS 11 does have better performance but it's much more frustrating as a phone OS to me. Someone at Apple is dropping the ball.
You won't see me go "I think I'll switch to Android now because my iOS device is horrible" but... trust me, I'm highly considering that all the same. Especially now that Google has cleaned up their act an Android 8.0 Oreo is a far better experience UI-wise compared to the abomination that is iOS 11.
iOS updates past iOS 4 have been progressively worse for me... each year taking away from "usability" in one way or another to introduce gimmicky interface ****, and I was especially enraged when "swipe right" on the lock screen turned into a camera launcher with no way to disable it. But I lived with it for 6 major releases of the OS. Now that the camera is shoved into my face even on the notification center, something NO OTHER MOBILE OS DOES, I'm probably just done with iOS updates altogether until Apple reconsiders at least that decision. Though my pain points lie in far more things than just the camera.
Edit: nope, too late now to go back to 10.3.3. Great. I'll just switch the sim card over to my Android 8 device in the mean time then. At least notifications work properly there.
