A hidden shortcut worth turning on
Back Tap lets you trigger a frequently used action just by tapping the back of the phone, with no need to touch the screen at all.
Good actions to assign
Screenshot, Control Center, and Home Screen are all solid choices. For anyone who finds one-handed use or pressing physical buttons difficult, Back Tap also works as a lower-effort alternative gesture. You can even assign it to a custom Shortcut you've built for your own automation.
