Screen Rotation? (Even if only 180°)

[system]

Sorry if I missed a setting somewhere…how do I toggle screen rotation?

As it is right now, my charger port is on the bottom of the tablet, which means that it’s rather unconfortable to play with it plugged in…and also potentially damaging to both power cord and tablet.

I completely understand if the screen needs to be fixed in the portrait position (as opposed to landscape), but would you please at least enable screen rotation on a 180° basis?

Thanks!

I’m only playing on me wee little phone so I don’t know if there’s a difference in the apps for different devices but I don’t have an option to rotate it on my phone.
