Hi there
Sorry to disappoint, but the gloss coating has nothing to do with the color.
I have the very first batch of S3 from Samsung's official launch in Malaysia, and the button on this model was 100% identical to the rest of the phone's front.
Just as blue, and not a tiny bit of difference.
Last Sunday I followed friend of mine to a Sepang racing circuit, for a truck day, and while climbing out of a freaking Ferrari with stupid bucket seats, twisting myself
like a motor skills challenged person, the phone fell out my pocket and the screen cracked.
Monday morning sent to Samsung for screen replacement, and the first thing I noticed upon collection, was that the button was different, "purple" different.
I ask that nice dude behind the contour, why did he gave me a China made screen replica (just teasing him), while looking at the damaged part right next to it, being clearly
so much different. He was going out of his way to assure me it was a genuine part
And explained that certain batches, come in slight different colors. Which is not intentional,
simply poor effort on the quality control.
cheers,
and have a good evening
Seba
