I was playing around with the airmouse Rii I25 and then this menu showed up. After closing this app I couldn't find it anywhere .
Seems a HW info/test page in Chinese and not an APP. Undocumented features are not that uncommon. Probably triggered by a key or key sequence on the remote not available on the original.
I can't reproduce that key stroke that triggered that page, another thing after I turned off and on the zidoo I was welcomed with the choose language screen and size screen setup then I got to the home screen. Kinda weird.
