This is just me, I never use cases or screen protectors of any sort. But in doing so, I never set my phone down on a hard surface. As strong and durable as the 7000 series aluminum is, it's still chips and flakes fairly easily pending the circumstance. Especially black, it's going to look worse than really what it is. But with the camera bump, it's going be the first point of impact every time because it protrudes from the rest away from the iPhone.Most people that care about these cosmetic issues use a case on their phone. If you are going without a case you have to expect this normal wear and tear.
