thanks so much this was the perfect app to keep the backlight on, also another thing I observed was that the cpu of the tablet was still on screen and capable of being used if we could see without the backlight but since we cant it looks as though the screen shut off, and after I installed this backlight program I didnt have the issue with the backlight going off during use anymore. tahnk you very much as I like the tablet and that seemed to be the only thing ti arise that needed to be addressedI solved the problem with this app : https://play.google.com/store/apps/details?id=jp.co.intri.backlightswitch, by keeping the backligth ON.
