I'm genuinely curious - why do people want the "lay flat protection" for the front glass? It's gorilla glass that virtually never scratches or breaks as long as you're not dropping it from arm height onto concrete. Additionally, who actually lays their phone down glass first on a table anyway? Mine is always face up so I can see who's calling, texting, emails, etc.
I have a case that has glass protection. What I find is the lip around the glass immediately captures dust and pocket lint all the time. It's also harder to wipe the front face as dust just gets caught at the edge where the lip meets the glass if you try to wipe the front. Furthermore, the lip makes it slightly harder to register finger taps at the sides of the LCD screen.
I've since ditched my case with "lay flat" protection and the front of the phone stays much cleaner and easier to keep dust and smudge free with a simple swipe across my jeans.
