After a few weeks or at maximum 2 months the case of the Xperia Arc develops a crack above the sensor on its front.
At first it's very small but it'll grow.
Sony Ericsson knows about this problem and said it's fixed with Xperia Arc S and you can get new, fixed covers that won't crack anymore for the Xperia Arc, too when you bring it to repair.
A long time we all thought Sony Ericsson would have fixed the issue, because no Arc S owner reported a crack on his device. Some users even sold their Arc to get an Arc S without the cracking issue.
But today one user posted a pic of his white Xperia Arc S with the crack.
That means the annoying problem isn't fixed yet and the new "fixed" cases will crack again.
I really hope they bring up an other fixed case that really fixes the issue.
If you think about sending your Xperia Arc to Sony Ericsson to get the new case SE mentioned, I'd say better don't do it as you'll have the same problem again and you're without your phone for a while.
