MAAAN! I thought I was the only victim lol... Went to sprint to claim this damn smudge and they told me they couldn't exchange it because it was from regular use and that not until the phone started showing "touch-failure", like if the phone would freeze or anything like that. I did notice at times the phone will momentarily freeze for like 10 -15 secs, and told them that it would do that. Only thing they told me was to take it back when the problem was present... Called asurion, and they told me I was out of the 30 day warranty they offer. If I want a new one, I need to pay $50. Aint this about a B*ITCH... I'm goin back to sprint tomorrow, lettin them know other ppl have been getting replacements for this type of problem.
