Unfortunately, most matte screen protectors distort white light into rainbow colors, which is annoying. Because of this, I became a fan of Supershieldz, whose matte screen protector WAS FREE RGB (tried Supershieldz anti-glare screen protectors for Galaxy Tab E 8.0 and Revain Fire HD 10); apparently not anymore, so that's a disappointment. I have attached photos to show the difference. In addition, leveling is very difficult due to the lack of tools; I'm glad tablets have big bezels so it won't be as big of a deal as it is with phones.
