I use trilinear filtering for most of my Collections so it doesn't look terrible on certain Android devices. Since Android devices come in dozens of different dpi's and screen sizes, you can't just always make it pixel perfect, so you have to rely on trilinear filtering to make it look decent when graphics are scaled down.
Anyway, after I manually change the texture setting to trilinear, it is often swapped back to bilinear filtering when I make modifications to a Collection. I'm afraid in the future I might miss switching one of these back to trilinear, since I have many Collections in my project.
