I am constantly doing it when attempting to scroll up. I hate to sound like I'm complaining again but does anyone know of a way to deactivate this feature? I never use it and I keep inadvertently pulling it down
On certain apps, they designed the Notification Center to not drop down on the first swipe, but requires a second swipe. They made it so only the tab sticks out from the Notification Center, but it leaves your app in focus. If you don't pull down on this tab in a couple of seconds, the tab will automatically pull back up as if nothing happened. I believe only iOS 5 compatible apps can program for this feature, otherwise the Notification Center will drop down like it should.
I believe whether it shows the tab is dependent upon whether the status bar is visible. i.e. if it's a full screen app like the camera, where you don't see the status bar at all, or a video, where you don't have a status bar unless you tap. Basically, if you don't see the status bar, you'll get the tab and have to swipe twice to get the notification center.
As for accidental swipes, no, I haven't had any accidental swipes. At least not since before the beta where they made it so you have to swipe twice for full screen apps. Even then, my only issue was with the camera, when switching from video to still while in landscape (where the switch is pretty close to the top of the screen).
I never run into it when scrolling because I always start my swipes in the middle of the screen anyway. I'm a pretty short swiper, maybe about an inch at the most. I rely on the momentum/acceleration if I need to scroll a lot.
(oh, how many times I thought to myself, "that's what she said")
You can disable it altogether or change the gesture that activates it, but I'm not aware of a way to tweak the sensitivity of it. That's part of the OS and you would have to adjust the touchscreen sensitivity for everything, not just this.
In regards to your threads that were locked by another mod tonight: I have repeatedly warned you against starting new threads all time for your frequent complaints about iOS. Please continue to use your general complaint thread for these concerns and questions. Your questions in the threads that were locked could have been asked there.
Also, don't assume that no one checks the jailbreak sections. Myself and many others here refuse to use the app due to its limitations. We do see and promptly reply to the threads there.
