15 Enable Reachability
iPhones displays have gotten big, and they’re probably only going to get bigger. That’s great for watching or viewing content, but it can be tricky to navigate your device with such a large display. Thankfully, there’s an Accessibility feature called Reachability that helps.
You can turn on Reachability via Settings > General > Accessibility > Toggle Reachability On.
Once it’s enabled, simply double tap the Home button (don’t press! just tap!) to bring items at the top of your iPhone display within reach. That includes features within apps or on the Home screen.
On the iPhone X, for example, Reachability makes accessing the Control Center much easier.
