I think some of your phone's would come with screens that weren't so shiny. Usually when I'm on the go, it's hard to see who is contacting me out anything at all for that matter because of the glare on my screen. Maybe a screen that you're able to see in the sun?
Unfortunately Koodo is only a service provider not a phone manufacturer. So in order for phones to have a glare free screen it would be entirely up to the manufacturer to make that happen. If you want to be able to see the screen during the day time, you would have to turn the screen brightness up which normally helps, but doesn't take away glare.
