I have a 4K stick. When connecting to the device in the mobile app (iOS) there are no volume buttons or power button.
However, I can use the voice button in the mobile app to say “volume up/down” or “power on/off”, and they all work. If I can do that, why can’t there be actual power and volume buttons in the app instead?
I have also found unofficial apps that have working buttons for power and volume for the 4K stick. I prefer the official app because it is much more polished, but find it frustrating these buttons are missing.
