Thanks for the speedy response. On close inspection I noticed that there is a small magnet on the front cover top left corner about 1 inch from the top. almost invisible but can find it when we run a coin over the surface of the front cover. When the back side of the note 10.1 meets this magnet, screen switches off. I noted that by placing a magazine/ booklet between the front cover and the back when using in flipped over mode: the screen does not switch off. A small victory. But wish that samsung provides a solution 2 disable this magnetic screen off feature through a menu option.
