i love the way my m8 feels without the case but infortunately i've noticed hairline scratches that i dont know where i got. I havent droppd it. I know theres clear wraps for the back of the phone but i dont feel like wasting 15$ on one. So can i just use one of those cheap screen protectors that come in the box when you order cases? anyone ever do this? is this a bad idea? I've also already got a clear case but i dont like the extra added bulk
