It has some smudges, but I'm not sure if it's my fault for not cleaning it well. It feels good to touch and the button works fine.
Irrelevant to this specific product, but if the screen is broken and you don't have a good heat gun to replace it, good luck. It took me 2 hours to replace the screen, and 1.5 hours to clean small pieces of glass that were stuck! It's like cleaning an egg, but the shells just won't come off, they keep breaking into countless tiny pieces and the egg is an ostrich egg
