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!
