Well, I did with a unit just out of the shop. Shop refused to take it, Nokia told first that it is due to scratches on the screen, after I've put it to their attention that scratches are on the in-box protective film second answer was that it is due to mechanical damage to screen 'cause I e.g. have been sitting on it while in pocket. So not covered by warranty, offer to replace the screen for euro 170. Took it back in as is condition, have that nice answer in writing and final recommendation to come to state consumer protection agency and sue Nokia if I feel like it. Feeling pretty pissed off sincerely.
