Slight correction on that last comment. Sorry. I found one area that seems to be a bit dark in very bright sun (maybe noon-1) . The call log telephone icons blended a little into the background, but were still a little visible. Might need something a little lighter around the edges to help that area. Or lighten the background for them a bit maybe. But otherwise, I played with a lot of the phone today and didn't see anything else that jumped out at me as far as visibility.
