If you're holding one of the larger iPhone models, it can be difficult to reach the top of the screen with one hand. Luckily, Apple created a feature called "Reachability" that essentially lowers the top of the screen so you can reach it. It works on iPhone 6 and later. Here's how to use it.
What is Reachability Mode?
Starting with the iPhone 6 Plus in 2014, Apple began releasing iPhone models that were much larger than before. Some journalists called these sized phones “phablets” (a portmanteau of “phone” and “tablet”) because they seemed unusually large at the time.
Because of the size of the iPhone 6 Plus, it was no longer easy for most people to reach every part of the screen with their thumb while holding the iPhone with one hand. So Apple created a new feature in iOS called “Reachability” that reduces the top of the screen using a software trick to make it accessible. Here's how you can enable and use it.
How to enable Reachability on iPhone
To use Reachability, you'll need an iPhone 6 or later — in other words, any iPhone released in 2014 or later. You'll also need to have the feature. To do this, open the Settings app (which looks like a gray gear icon) and go to the Accessibility section.
In Accessibility, select “Touch”.
In the “Touch” settings, tap the switch next to “Reachability” until it’s on. When it’s on, the switch will be green with a toggle on the right half of the switch. (If Reachability is already on and you don’t want to use, you can also turn it off using this switch.)
After that, exit “Settings”.
How to use Reachability on iPhone
Now that “Reachability” is enabled, you should learn how to use it.
On an iPhone without a Home button, swipe down from the bottom edge of the screen. In other words, tap the line at the horizontal bottom of your screen (or the area directly above the line) and swipe down on it.
On an iPhone with a Home button, gently tap finger on the Home button twice without pressing it – in other words, press the Home button, but don't "click" it.
When enabled, the entire screen will move down by about one-third of the screen height.
If you want the screen to return to normal, run the “Reachability” shortcut again.
