Gestures on the iPhone 15 Plus

Double-tap the back of the iPhone

DocumentedInput: Back Tap (double)

Requires: iPhone 8 or later with iOS 14 or later (DBP Shield itself needs iOS 17)

Double Tap
Shortcuts: your DBP Shield shortcut

Back Tap runs a shortcut from your Shortcuts library, so first create one in the Shortcuts app with DBP Shield › Send signal (Trigger: Back Tap (double)). Each double tap runs it once, so one double tap is one event. Apple doesn't say whether Back Tap works while the iPhone is locked or in a case: build the shortcut with Send test signal first, try it, then switch it to Send signal.

Two triple taps on the back within 8 s: works on every supported iPhone, including those without an Action Button, and a triple tap fires by accident less often than a double tap.

Gestures are set up in the phone settings as shown, then combined into a trigger recipe in the app, where practice mode shows step by step whether a gesture would trigger.
