I'm the same way, grab a tpu case off Amazon. They fit great and hardly add any bulk. I have the black one and it's soft touch backing has a few scratches but it's not as bad as the phone itself getting scratched. I think I spend less than $10 on it and I've had it for a few months now. Really nice case thus far.
I have a dedicated pocket for my Epic, just the phone, no rocks, no keys, no fishing lures, no curling irons, no nail clippers, no hardware, no tools, no lighters, no change, no cigarette rolling machines, no make-up, no guitar picks, no peanut butter cups, no gum and definitely no LINT!!!
so i decided to do something about the scratches took the phone in for screen blotches and vertical lines. sprint stores here in Spokane are idiots, they didn't want to exchange it, so i figured if im stuck with it for a while ill at least make it look pretty again. Some scratch x got rid of all my fine scratches and my phone looks brand new!. Very happy so anyone looking for scuff removal or fine scratch removal from the plastic scratch x works great
After you buff the scratches out you should consider a clear skin for it. It would make the phone scratch proof and you could still go caseless. I've seen ones from skinomi and ghost armor for under 20 bucks.
