If you have an iPhone X or newer, you might miss the old hardware Home button. Even if you have another model, you might want the options and functionality of adding a virtual Home button to your screen. This is a great hack because it provides fast access to features that otherwise require gestures or multiple taps. To enable this virtual Home button:

1. Tap Settings.
2. Tap General (skip this step on iOS 13 and up).
3. Tap Accessibility.
4. Tap Touch (only do this on iOS 13 and up). Tap AssistiveTouch.
5. Move the slider to on/green.
