how/where to replace scratched silver frame

Replacing this part is a very complex and difficult job. It would most likely l, almost certainly require the replacement of your screen as it's almost impossible to remove without breaking (even by a seasoned phone repairer)

Cost. Screen $180, rear frame with bezel $20

To have it done professionally it would be US$250 (that's including a new screen, if your lucky you may find a repairer that can remove screens with out breaking, however very rare)

The above answers are exactly right. To put it simply, unlike the origianl galaxy ace phones that silver part is attached to th circuit board in the middle so to replace it you have to replace the main part of your phone which is just not worth it. Its superficial so live with it or do what i do and sell it on ebay as 2nd hand and use the money towards a new phone ...it will be cheaper tha repairing ur one

Nonsense it a very easy repair.......to anybody with a little skill....

I took a good chip out of my Galaxy S5 Neo after dropping it on a concrete tile floor. It's not visible with a black case (the phone is black) - but other than that you would be better off paying for a new phone. Even though the cost of a new phone can be upwards of $700.00, you're better to avoid paying almost $300.00 for parts and repairs of this purely cosmetic problem. Look lad, it may not look pretty, but if you don't have performance issues, I wouldn't fret.

Just be more careful when you get an upgrade!
