Hi everyone! I bought my tamagotch connection about a week ago... when i first started it everything was fine but a few days later the screen started to look dim. i compared it to my friend's tama and her screen is MUCH darker. i went out and bought another battery to see if that was the problem, i changed the battery yesterday and it seemed for a day it was good and now today its dim again...has anyone else had this problem? I'm thinking of returning it and getting a new one...but then i need to give up my tama!! HELP!
