How to do it

1. 01

   Open Settings > Accessibility > Touch > Back Tap.

2. 02

   Choose Double Tap or Triple Tap.

3. 03

   Pick an action. Flashlight, Camera, Screenshot, and Shortcut are the ones that earn their place.

4. 04

   Leave Settings and tap the back of the phone, firmly, near the camera.

A light tap is ignored on purpose, so it does not fire in a bag. If a new case seems to break it, tap harder before you turn the feature off.
