[Q] Micro Arc Oxidation failure?

Does anybody has got the problem with the ceramic surface which is shown in the following pictures??

Looks like a major problem with the production technology :-(

You have to be really dumb to release phones like this. This is not the first time HTC has done this. QA obviously sucks at HTC

As a potential HTC One S owner I'll just inject a few words into this thread.

Most of the people complaining and spouting their opinions on QA have no frigging clue about metallurgy or SCM.

I have consulted for companies that design & sell 100k-1M units. There are so many steps in the process until that phone gets to your hands (at a very low price, considering the complexity!), that the mind would boggle - and sometimes it's amazing that anything works at all, ever.

As for the coating process, I doubt that HTC mills the metal or has plasma baths in their offices. All this stuff is outsourced. And in China its hard to ensure that you get what you pay for (or specify) - Ive seen this happen with PCB laminates, components where the BOM says one thing, and a middleman will just ignore it and pocket the difference.

Maybe the base metal was a 3003 alloy instead of a 6100, maybe it was not degreased well enough, maybe some employees handled the edges, perhaps the plasma bath was too cold, or things not given enough time to warm up due to the units/hour presure from the line manager. Moreover, unless you destructively test the devices it's very hard to spot such failures unless you decided that's what you're going to look for.

Of course I would be disappointed when my One S has a chipping issue, but it seems like HTC is being responsible and has quickly acknowledged the issue, without telling the customers "you're holding it wrong"


FWIW I own a HTC Desire, a Nokia N79, SE K750 and lots of old Nokias.

surface flaw, no scratch

Have been at a surveyor. He told me this are doubtless no scratches. And indeed I did not drop my phone. On the pictures they took you can clearly see that there are no scratches aroud the affected area, which should be there if I dropped the phone.. What I think is the my reseller will tell me I am stupid if I show those very little flaws to him
Let's hope for HTC

Thread Cleaned​

I have cleaned some posts from the last few pages. Some of the comments are not acceptable. Further trolling will result in a infraction/ban. Do not engage trolls, just report them and let the moderation team sort the problem. In short, dont feed the trolls!​

^^Good post psch0t1c^^

I'm not sure about sending it back to HTC in case they do try and say I have damaged it which I KNOW I haven't. I'm inclined to wait a few more days and see if the problem becomes more widespread and HTC become more aware of the problem.

I think we should ether do a new thread or add a poll to the OP so we can gauge how many people are affected thus far.
