Are you talking about screen replacements or scratches on the steel?
Because this thread is about scratches.
You think a "quality issue" is stainless steel that behaves like stainless steel -- at least according to your post.
What do you expect these things to be made from? An alloy of unicorn horns and Adamantium steel harvested from clones of Wolverine?
Like someone else said: "It's a phone, FFS."
We are trying to defy physics in this thread, it's fun to watch and read.
