Holding the side key does nothing
Three things can hold this up, and on a Samsung it is usually the third one.
1. Make Folio the digital assistant
- Android Settings › Apps › Default apps › Digital assistant app.
- Pick Folio.
- If it was already Folio, pick something else and then Folio again. Android only starts Folio's assistant service when the choice changes.
2. On a Samsung, point the button at it
Settings › Advanced features › Side button › Press and hold, then chooseDigital assistant. Out of the box that hold belongs to Bixby or the power menu.
3. If you use Good Lock
RegiStar intercepts the side key before Android does, so whatever it is set to wins. Set RegiStar's press and hold action to Digital assistant, or turn RegiStar's side key handling off.
This is worth checking even if you set RegiStar up months ago. It is the most common reason the first two steps look correct and nothing happens.
