Screen freez

Hi, I just got my luma-pad and its functioning fine. However, every time I start one of your 3D programs, the 3D effect works for a little while. Then the screen freeze and goes to black.after I turn it off and back on It function alright for a while.

Is it defective? any help?

Hello @aalkaabi!
This could be a screen saver/sleep setting. Could you take a look at your current settings? You can also reach out to for further trouble shooting and they will work to see what’s going on. - Marlon
