The HTC One S and One X are wonderful devices... if you read my One X review you'll know i'm a big fan and (spoiler alert) i'm rather taken with the One S too... but it does seem that there might be some hardware problems coming to light as the devices hit the street.
The first issue, which affects the One X, is one that I mentioned in my review. On the One X, the camera module on the back protudes considerably from the device and the plastic covering the camera will touch the surface on which you are placing the device face up. The camera surround doesn't have a lip and I reasoned that this might leave the device susceptible to scratches. It seems I was right... I have a scratch on mine - and i've had another report from a user that they have the same. :(
The second issue, which affects the black One S, is more worrying. I have been using my One S almost exclusively over the long weekend and I noticed that on the top edge of the device, it appeared that a small piece of the black coating had chipped off revealing the lighter metal underneath. Now, I should point out that I am EXTREMELY careful with my devices so I wouldn't expect this to have happened and I also hadn't dropped the device. I initially put this down to 'I must have knocked it against something without realising', but then I noticed a second area start to 'go' and my worst fears were confirmed with a Tweet this morning from MoDaCo member piter1225 highlighted a XDA-Developers topic where others have had the issue. It does seem a problem with the 'micro arc oxidation' coating that is on the black One S and not the grey device.
I have reached out to HTC for comment on both issues, but in the interim, it'd be great if One X / One S owners could post here if they are / aren't experiencing similar problems.
