How can I rotate display and switch to tablet mode automatically

Hi. I was expecting the Chuwi Ubook 11.6" to switch automatically to tablet mode when detaching the keyboard, but it doesn’t. I need to go into settings and set it to tablet mode.
Even more surprising, the display doesn’t rotate automatically between landscape and portrait when you move it around. Again, you have to manually alter the settings!!!
The machine cannot possibly be that bad.
Anyone knows how to get this to work properly?

Hay una opción para ello, mira en configuración de pantalla y desactiva el bloqueo de rotación.

So someone has the solution?
