Legacy iPhone behavior

How older iPhones differ, and which settings never reached them.

Settings that moved or disappeared

Apple reorganises Settings regularly, so an instruction written for an older release can point at a menu that no longer exists.

Settings

Home button navigation

Available

On an iPhone with a Home button you press it to go home, press twice for the app switcher, and there are no edge swipe gestures.

Settings > Accessibility > Home Button

3D Touch

Available with variation

3D Touch sensed how hard you pressed the screen and was fitted only to the iPhone 6s through the iPhone XS generation, before being replaced by Haptic Touch.

The setting exists. Choose your iOS version to see the exact path.
