HTC One S ceramic nanocoating flawed?

HTC One S ceramic nanocoating flawed?
One of the most touted features of the HTC One S is its premium construction. In particular, one of the finishes the smartphone comes in is created using a process called Micro Arc Oxidation. As a result, the device's unibody is made super strong and its surface gets covered by a ceramic layer. 

Sounds so fancy, doesn't it? Well, it looks like real life results may vary, as some unfortunate HTC One S owners are now finding out. According to several reports, the coating on the smartphone's top side is starting to chip off for no obvious reason. Not a single one of the users who are having this issue have dropped their device or mistreated it in any way. Some say that the sharp edge on top is to blame, while others assume that the coating itself is flawed, but a definite reason as to why the ceramic layer on these devices is starting to fall off has yet to be stated.

HTC One S owners, are any of you having the same issue? If so, feel free to leave us a comment below, and if not, better keep an eye on your device. We will be watching out for a statement from HTC regarding the flaw and will update you as soon as we have more information.

Strongly consider getting the extended warranty! 40 days into the purchase and my HTC One S screen has cracked. It was NOT dropped - simply caught the edge of a coffee cup. I have the Diztronic case - nice but did not help apparently. HTC and T-mobile said I'm out of luck. Guess I'll have to get one of those replacement kits on youtube :(

I had 3 HTC One S black, and the final one got returned for a refund. First one chipped on week 1 from simple use and keeping it in my jeans pocket+ the HTC slim case. Second one had USB chipping and wifi/battery problems Third one came chipped already at the usb port. Fitted a gel case on it and kept if for 2 weeks until i couldnt bare seeing how quickly the chipping from the USB area had grown. Throughout all my communication with HTC customer service in the UK, initially they were 'doing the replacements through the retailers as a good gesture' and then 1 month later they announced to me that the damage is 'cosmetic' and it is not covered by HTC warranty. Any repair would have to be paid. Also they repeatedly denied that HTC one S line has any flaws, and this is merely a few handsets that may have had an issue, hence they would not be improving their manufacturing process in any way, as rumors said in the forums. To my utter disgust, they had the audacity to deny that HTC ever claimed that this phone does not need a case due to it's durability!!! (there is an official video on youtube about it!!) I have a record of all my discussions with HTC about it. It is available to anyone wishes to investigate further, but personaly i think this issue needs a good lawsuit against HTC for false advertisment. I am now waiting to revceive my SGS3, never going back to HTC after 10 years of using their phones. Customer service like this should be the downfall of a company.

well after all the hype htc made about the nano coating or whatever they did and this is really an issue then this is a huge fail for htc,you would think they would test it before making such claims.

Apply your own paint.

Is this for real? How comes? From the process we saw it wasn't coated, it was electrocuted(by thunder god zeus) lol. So from my understanding, if u able to scratch it, its should show the same color and same material.

We just talked about this in a thread about Gorilla Glass at another site. If this is the same ceramic that we discussed in that was a bad idea to have the phone coated in it. Might as well coat it in glass...

Shocking, i really was looking forward to this phone but if the build quality is this bad then I won't buy it. When it comes to build quality Nokia and Motorola are two of the best IMHO.

I hope for the owners that htc isn't comming up with a cheap problem solver like apple did with the iphone 4(bumper sticker) cause you pay allot for a new phone even if it is only $300 it should be of a decent quality that doesn't damage itself.

since the one s is still not available in some countries yet ,they can reduce the price and bring it closer to the one v

No, that's paint or a clearcoat... This is a new tech.

Not even. The desire z had just a slab of aluminum for the back cover.

I'm not paying $700+ (and if it is subsidized; you are still paying in overpriced data) for a device with gorilla glass and some amazing new harder-than-ceramics metal coating to have it chip in the first two weeks of usage. Also, I have never, and will never, put some ultra cheapo $5 plastic cover on the back to combat poor build quality or put some ugly screen-dulling garbage over the top of the screen. What is the point of arguing over screen quality if you're going to apply some amateurish crap so you can never see the quality? My original Droid Incredible got chips after being dropped on concrete from shoulder height. You can barely see them. The plasticy back was hardly nicked at all, and you can buy a new one for like $15. I would much prefer replaceable back (if it's going to chip or scuff at all) than a permanent one. Honestly, the One S was out of the running already due to lack of NFC. REALLY hope the SGS3 is what I expect!

Sony has one of the best build qualities , my old Arc survived a 1 meter drop onto tile and only had a small dent on the edge , and the screen survived a drop onto a rock ,only scratches ...what htc did here was they made a piece of art ,excluding the possible drops and pocket scratches

Sorry mate, but my 3 previous HTC's all tasted the tiled floor My Incredibke S fell from 1 storey high, and survived, after hitting the tiles, only with some minor dents, My Sensation fell nearly one storey high, when i was dangling upside down off a gazebo and crashed on the upper edge onto 2 by 4 bricks, having some dead pixels, which later throughout the week disappeared! Now my Sensation XL has fell 2 meters, when i jumped off a wall, and my phone slipped out of my pocket in the air, and it has no signs of a fall! FINALLY a fat woman had sat on my wildfire, which cracked the screen -.- So i think HTC wins the best build quality!

...and my phone (made by Chuck Norris) fell from third floor onto street - only damage was on the street: they still have that hole on sidewalk, it is about feet deep!

u do know that they make clear screen protectors right? those anti-smudge ones suck. they really mess with screen quality.

i personally put back covers just to protect the screen from accidental falls.. the ones that will make you pay 200$ or so for a screen replacement. i could care less if the back of the phone was all scratched up, though. gorilla glass is a must too, in my opinion. i hate scratched up screens.

I know the black One S is made with Micro Arc Oxidation, but what material is the white One S made of? I bet it's the same polycarbonate material as the One X.

The second finish (the grey-ish one) is a gradient, anodized aluminum with a light-to-dark fade across the phone.

So much for "premium build quality" Lol

is it just me or did anyone else have a flashback to a nexus 1 while looking at those pictures. paint problems.. blah. get a case!

Yeah I agree. As much as phones cost nowadays, I suggest everyone to buy a case and a screen protector as soon as possible. Maybe the air causes a strange chemical reaction with the coating, causing it to peel off the phone faster than expected. At least with a case, that issue is much less noticeable (or even nonexistent if you're lucky).
