Can I replace that silver bezel around my camera?

Hello Dylan Good morning, I wasnt sure what exactly you are asking for but if I may had understood right you are searching for a piece like that: http://www.ebay.com/itm/Samsung-Galaxy-S...

Now to replace it I wont find a specific guide, but this one here from iFixit looks excellent for me, just unmount your device following the guide till you reach the part you need: Samsung Galaxy S5 Teardown

and once complete just go backwards on the guide.

But if is just the little frame bent and only visually I would recommend you to let it really break something like screen or what ever because it can always go wrong and loosing a s5 because of a rear scratch may sound dumb

Cheers mate
