I checked the website and I see its a chip and O/S for the '5 point' touch contact system used on the Tablet. When I click on the app, I get a screen with a couple of lines about 'Calibrating the screen' which if pressed tells me not to touch the screen while it does its thing, which it does. Is that all it does as there is nothing in the instruction manual regarding this app? I wondered at first is it a Graphics 'drawing' program but if it is, how do you 'open' it? The Bauhn Tablet is a great device but the manufacturer presumes you know what it does so they dont bother to provide details. This is my first post and a very new user of any form of Tablet device.
