For those who asked me about the SGP Curved Crystal SP, I have applied the SP onto my SGS3 already.
The fit is good, no bubbles and clear screen with no rainbow effect.
However, the way I successfully applied it, I think I can win a Gold medal for it...Haha...
It's not as easy to apply as the normal flat SP. Because it is curved and cover the WHOLE screen, you cannot afford any misalignment at the sides all the way down. No room for mistakes.
And don't listen to the Instructions given. It asked you to peel off the sticker for the front first and then only peel off the back surface to stick on the phone. If you do this, the front surface might get scratch if you use the Squegee to push out bubbles.
I did not peel off the front protection sticker until I successfully apply it and push out all bubbles. Then when you peel off the front sticker, do it gently so that you won't pull off the entire SP.
Fortunately, I managed to do it successfully at one go. Fot those who screw up, don't worry. They gave 2 SP, so you can have a second try. Now I have 1 extra SP to keep as spare. yeah!
And I put back my Casemate Pop-case into it. Fortunately it didn't push out the side of the SP. That was what I worry because the SP goes all the way to the edge of the screen.
I'm happy now
