I have a book cover my my Note 10 2014, and I find the smartcover behavior not so "smart". It is, in fact, extremely stupid and turns the screen on and off at completely random times. I don't have the same problem when it is off the cover. Props for Samsung for figuring out how to make it sense that it is in the cover (it is not just a light sensor) but the "smart" part of the feature is rather frustrating, and at times infuriating.
Thanks!
Thanks!
