HMD Skyline

Ships with Android 14. The HMD Skyline Business Edition reports a different model name and has its own entry without the Custom Button: HMD's Custom Button guide covers only the HMD Skyline.

Gestures on the HMD Skyline

Double-press the Custom Button (programmable key on the left side)

DocumentedInput: Extra key

Requires: HMD Skyline (ships with Android 14)

Set it up

  1. Settings
  2. Custom Button
  3. Double press
  4. Pick the option that opens an app
  5. Quick signal: key

One double press opens the app, so one event means one double press. Out of the box the double press turns on the flashlight; press & hold is set separately and can keep HMD's own Dial emergency contacts action, which calls your emergency contacts and texts them your location. HMD's guide says only "select from the available options" and that the key can "open apps"; the exact label of the app option is not documented. A double press of the power key is configurable too, but no source says it can open a chosen app, so it is not listed.

One press and hold opens the app, so one event means one hold. Out of the box the hold switches between vibrate and sound. Mapping it to our app replaces HMD's Dial emergency contacts option on this key. HMD's guide says only "select from the available options" and that the key can "open apps"; the exact label of the app option is not documented.

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.
