Can I Change the language of the rockchip app?

There is a hidden application something to do with the rockchip etc… after clicking the launcher version button 5 times. It opens a menu to run what seems to be a test application and other installed apps. One of which is a rockchip app with a chinese name. When opening it i’m met with a menu that looks something like a bios settings screen but completely in chinese. I’m guessing it’s the kernel options etc…

Is there anything fun that can be done with this app?

Hi @iKriz this is a hidden app that we use in the factory for doing production line testing. We do not recommend you to operate this app, as it may put the projector into settings that are not supported outside of the factory.
