iPhone 7 Plus Matte Black Paint Chipped

I have been using iPhone 7 Plus Matt Black for about one month with fully covered by a TPU casing and full screen tempered glass most of the time. I just open the casing once a week to wipe the dust off from the phone. Until yesterday when I take off the casing, and notice there is something at the edge of the phone body next to UP Volume button. At first I thought it just the dust. I try to wipe it using microfibre cloth as usual. Until I look closely it is the metal part of the body. It seems that the black anodised paint had been chipped off from the phone body. I am really disappointed with what happen to the phone because I was using it very careful.

I have chat with Apple Customer Support and it is not covered under warranty since it is under cosmetic damage. Seems that the anodised paint quality on iPhone 7 is same as what is on iPhone 5. The iPhone 7 body paint will chipped at anytime regardless you are using it very careful. Just to share with you guys 😉
