Now we don't recommend you doing this with your own white handset, but the Sony Xperia S
is supposed to have apecial dirt-repellant nanocoating to fend off the grease of this world aiming to stick onto its pretty little shell.
We had a black review unit
, and we noticed that stains from your fingers actually stayed for quite a long time on the matte plastic back, until they fade out, like with soft-touch plastic, but the white version shouldn't suffer much from that.
What it can suffer from, though, is someone writing with a marker pen on it to prove a nanocoating point, and that's exactly what a white Xperia S has been subjected to. The owner then grabbed a regular eraser, and removed every last bit of marker writing from the back, depriving the phone from its newly-acquired individuality.
Brave souls out there, indeed, but as someone rightfully points out in the comments: "other people just used a wet cloth". Watch the Xperia S desecration in the video below.
