HMD XR21

Rugged; HMD-branded successor of the Nokia XR21 (user guide model TA-1592). Two programmable keys.

Gestures on the HMD XR21

Briefly press a programmable key (the top key or the left side key)

DocumentedInput: Extra key

Requires: Nokia XR21 or HMD XR21

Set it up

  1. Settings
  2. Quick access buttons
  3. Press
  4. Pick the option that opens an app
  5. Quick signal: key

Both the top key and the left side key are programmable, each with its own Press and Press and hold action. Each brief press opens the app, so presses can be counted one by one. HMD's guide does not say how the two keys are listed in Quick access buttons. 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.

One hold opens the app, so one event means one hold. Keep HMD's Dial emergency contacts on the other key's hold if you want both. 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.
