Do you have the problem of the matt black chipping?

yes or no?

which week was your phone made? (check the serial number and it is the 5th letter o number)

how long have you been using your phone? when it began to chip?

let's try to understamd if it was a problem now solved....or if the new batches are still affected...
[doublepost=1486912207][/doublepost]mine is 7 128 week W and no chip gate, using it since 20 days

Why does this matter. It's not like you're going to not buy the iPhone. And Apple doesn't do exchanges for cosmetic damage

No chipping at all here. The number on mine is 8. Oh and I've had mine since launch day.

No chipping or marks after 2 months in a soft clear tpu case. The one it replaced had no chipping either after 3 months use from launch day.. again in the same tpu back cover.
First one was manufactured end of August/start of September, this one was manufactured mid November

It's funny because the media is referring to the finish as "paint". AFAIK, it is an anodized coating, something completely different. If the coating is chipping, it "might be" the surface of the aluminum was not prepped correctly prior to finishing. Any metallurgist's out there?

You can use Sndeep.info to find out when your phone is made. W is Week 51. T is week 49. V is week 50.

1) No?
2)T - Week 49
3)Almost a month

Could you please elaborate on the chipping? Only thing I notice when I hold my phone to the light at an angle, I see these tiny dot like markings that must've been caused by dust inside the case.

This is more accurate. It's a problem with the anodization process and it's not fully cured to the aluminum at the appropriate temperature. It's actually flaking, over chipping. Over time, handling the iPhone or cases can worsen the issue. There is no remedy for the situation. It's purely cosmetic.

I think it's certainly a manufacturing fault on certain batches.

I don't have any flakes or chips, but the backside shows very faint specks. Almost like the coating is thinner there. I'm certain it's not damage as it has always been used with a case. Is this something that's been reported before?

This has only happened within the last few days on my Matte Black iPhone 7 Plus and it's bugging the life out of me as I'm so careful with all my devices.

I know what you mean I noticed those tiny specks too. I don't think it's flaking, it looks more like dust particle rubbing in the same spot and sort of flattening the "Sand blasted" finishing which gives it that matte look.

That's awful - it should not be doing that. I would try contacting Apple for a replacement, but not sure that would do much good because the next one may do the same thing. I guess it's silver for me when I upgrade - even though I want black. Hopefully you get it sorted out.

This has also been in an Official Apple case from day one

I have the letter F. I ordered my phone on launch day but it came about a week after launch and then I took it back and got a replacement after 9 days because of signal issues.

The phone has ALWAYS been in an Official Apple case and I'm so particular with my phones. Every year I sell them on AS NEW because I don't even open up chargers or headphones and my devices are always immaculate apart from this one which I'm furious about. The marks have only appeared within the last week.

As with any other issue with a mass produced product, knowing the date and/or location of production is not a foolproof guide to avoiding the issue. All it amounts to is a waste of time and effort. Apple isn't going to let you sort through a dozen phones to find the one with the magical non-chipping serial number.

Code K. Week 42. 3 months now. Pristine condition. I didn't use case for 1 month but it was so slippery, now I'm using a clear coat ( it looks naked ) no regrets

Man I was torn between getting jet black and matte black. I thought it would be hard to deal with the scratches of jet black, but got it anyways. I'm sorry for the people dealing with this on the matte black, but I'm happy I'm not dealing with it.
