Accidentally Making Your Screen Drop Down
Another issue people have with their iPhones is that they accidentally drop down their whole screen.
This is actually thanks to an accessibility feature called Reachability, which is meant to help you control your iPhone with just one hand. This feature is triggered when you swipe down from the bottom of your iPhone’s screen, but the good news is that you can actually disable it if you want.
To turn off Reachability, simply go to Settings > Accessibility > Touch and turn off Reachability.
And that’s it; your iPhone’s screen won’t move down accidentally anymore. Of course, this means you won’t be able to control it with one hand, so if you miss this feature, simply repeat the same steps and turn on Reachability again.
