Except there isn't a problem.

You have trawled through an otherwise glowing review (one of the most upbeat out there) and picked out the one and only possible negative made in it. Then you have studiously ignored the reviewer's own admissions that a) the device he had was not final hardware let alone firmware (and wasn't even obtained legitimately) and b) he subjected it to inappropriate treatment. Heck, any intelligent person (even a teddy bear!) knows better than to mix sensitive electronic devices with sand.

That doesn't sound like you are doing 'proper pre-purchase research' - not least as you're ignoring the many posts on here that have said people have had no trouble with the screen at all, and anyway there are screenprotectors available if you're worried. That sounds like you're here to wind people up.

And you know what? Nokia are doing a bang up job of winding people round here up without your help, thanks.
