My ex-N9 had this on the usb cover after a couple of weeks.

But to see this on the body surprises me.

It looks like the black PC got clear coated after all.

Why then they did not put a high quality anti-slippery coating in the first place?
I disliked how slippery the N9 had become after a couple of weeks after the matt effect had worn off, especially when holding it to make pictures.

This phone asks for a custom paint job.
