One of the must utterly infuriating problems I have on recent iOS versions is the fact that swiping down from the top of the screen while the phone is locked will bring down the notification center and clear all of my lock screen notifications.
This happens all. the. time. I usually keep my phone in my pocket, and if I get a message or feel it vibrate, I will reach into my pocket and with my thumb and forefinger pull it out. Perhaps 50% of the time when I do this, my thumb ends up pulling the notification center down when I pull my phone out.
This alone isn't a big deal, I can just swipe it up again. The problem is that when the notification center comes down, for some god-knows-why reason, it clears the notifications that were just on the screen, meaning I'm now prevented from doing precisely what I pulled the phone out of my pocket for in the first place.
There has got to be a way to fix this horrible UX.
