Looking for a tablet and a nice wall mount


I need recommendations for an android tablet that can control HA please. It doesn’t need to be able to do anything else. It would be good if the display would be active when moving.
A nice wall mount is important to me. I don’t want to see any cables and I don’t want the mount itself to be visible.
It would be nice if the tablet were white. But that is not so important.
Thanks very much.

I use a couple of old ones - Android 7 runs Home Assistant perfectly well.

On motion activation, Fully Kiosk Browser allows you to do this.
