Guys,

When I first read this I thought the same thing that the device had been dropped... however I have just looked closely at my own device and the same thing is happening on the sharp edge on the left hand side :(

My device has NOT been dropped or mistreated in any way.

"It features aircraft 6,000 series aluminum which is treated with micro arc oxidation by blasting it with 10,000 volts of energy. This gives the metal a ceramic feel and causes it to become five times harder (that’s three times stronger than stainless steel).

The shell of the HTC One S is so durable that HTC claims that it does not even need a protective case. "

The shown devices were not droped. A lot of the One S look like this after one week of safely carrying . Belive me, your devices will show the same failure in approxamitly one or two weeks.

It looks like the brittle ceramic skin can't hold on to the flexible aluminum. Like I said major problem with the production technology.

The nice words of HTC are advertising words.
I am not surprised of the problem and I think it to be idiotic to have such a sharp edge. What else can you expect?

Is there anyone else who experiences the same thing?

Damn.. I really wanted the One S. Yet If the ceramic back is this easily damaged without dropping.. I might not get it. I hate cases.

Same here, this could be the only reason why I won't buy this phone. I never use cases because it makes the phone ugly imo. And I don't know if I want the grey version..

LOL...i noticed some spots up there too after reading this thread and was concerned at first but the white marks could be "rubbed-away" like the marks from fingernails on the back which was shown in a lot of videos ... just try it. ;)

hey, they use this stuff for satelites...

The blue one got another treatment. There is no ceramic surface which can come off.

There is no way to rub the damage away. The Oxidation to Al2O3 happens only under high temperatures. If the ceramic skin can't hold on the the aluminum it will be damaged permanently

Wow. This is making me reconsider my choice. Got a One S due for delivery tomorrow and might be tempted to send it straight back either for the grey one or for the One X having seen this.

So if any One S user reads this, could he/she share some experiences with the ceramic surface? Even if you do not have any problems at all. It would be nice to find out if this is just a bad product, or a common problem..

I've had mine a few days and not dropped it or anything, it seems to have started on mine though. If it gets any worse over the next couple of days I'll have to take it back, not sure what to do though as I love the phone and don't like it as much in grey/blue :confused:

Anybody contacted HTC about this yet?
