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

I use LAUT brand. I bought it from Switch. It is slim skin TPU case. The phone never drop or knocked to other hard object before.

What coating you use? is it nano coating?

haha. i also just touch up it with matte black paint. looks OK but not sure how it would be for long period. as long as can cover the exposed metal part then its ok to my eyes.

Beside using the casing, i also use skin which I did on my own. precisely cut to fit the side button (volume,silent,lock). Just today i peel off the skin because want to make sure what is it between the volume button. previously when the skin is still attached, i thought it is the adhesive residue.

this is picture after i touch up with black paint

i use Anchor Flat Black spray paint. i use toothpick to put the paint onto the chip area. very careful not to over paint.

I think later will be many more to start chipping. I dont know how to push them to include this under warranty. i went to Switch this evening and they said it was not cover under warranty. but they ask me to send an email to Apple US. i could not find any Apple support email on their website. So I just having a chat with customer support person and she said it is not cover under warranty. she said if i want to repair it will cost $100+ and the phone will be ship to any nearest Apple Repair Centre

This morning i saw there is another one chip paint. It is at the edge of phone body next to silent button. That one is quite visible. Haihh.

Did you go for warranty?
