I have used various iPhone screen protectors from SGP and PS. Recently I purchased the oleophobic. They are working exactly the same as the crystal, zero oleophobic properties. Has SGP changed them? I remember that in older oleophobic protectors the oils where quite easy to wipe with a dry microfiber cloth. And the coating lasted for months. In these new ones the oil just smears across the screen unless I apply water. Also in the older ones the water formed in tinny drops but now it just smears too. Has anyone had a similar experience with the newer SGP oleos? Also is there a better alternative? The only other oleophobic protectors I have heard about are green onion, but I have no idea if they are any good. Thanks.
