Has anyone else noticed some type of faint scrolling lines on their screens. I notice it more when on lighter backgrounds, like the blue ink splash. Both my behold II and a friends has the same thing. Is this a property of OLED screens, some type of refresh? They are horizontal lines and dont always cover the whole screen. I really read how awesome an OLED screen was supposed to be, but eh I think the Iphone screen is still nicer. Any thoughts on these lines, I doubt this is limited to two phones.
