Asus's ZenFone 7 and 7 Pro pages say a double-press of the Smart Key launches Google Assistant or your specified favorite app shortcut or action, and Asus's FAQ says the Smart Key settings (Settings > Advanced > Smart key) can open apps. On that screen, set the double-press action to open an app and pick Quick signal: side key; Asus does not name the option, so the label on the phone may differ. A single press still works as the power key. If the long press is given a custom function, it no longer opens the power-off menu (Asus FAQ). Asus does not say whether the double-press works with the screen off or locked, so test it. To keep a touch on the key from unlocking the phone, Asus suggests setting the fingerprint unlock method to Press only.
