Why texture quality get down built in iOS unity 3.5

I’ve met a problem that when I upgrade version from 3.4 to 3.5. Android texture quality doesn’t change. But iOS acquired apparent difference that the quality getting down. Thanks for help in advance:)

I figured out that texture setting GUI in 3.4 doesn’t have attribute quality level so when upgrading project to 3.5, its default value is normal. Set it best is fine.
