My entire messages screen looks different. I can't stand the color at the top. The contact pics look different and all the colors have changed. I can't figure out how to at least change the colors.
Welcome to Android Central! Let me guess--Samsung, right? This is one of the most common complaints about the Lollipop update on Samsung devices. I have yet to see any kind of solution, so I think you're stuck with it for now. You could always install a 3rd party SMS app like Textra or Chomp SMS.
