I don't see the visible line running down the edge of the Boox Go 7 described in this review. I think I have my Go 7 set to 70% brightness and the temperature turned all the way off. It might be that my eyes are not sensitive to the line. The main issue that I have is that the touch screen is too sensitive around the edges. Some times when I am holding the Go 7 reading a book the page turns when I do not want it to. #
