my 3DS doesn't have any dead pixels, but it does have a very bright pixel in the right bottom corner

Jackpot!My dead pixels experience with Nintendo,
DS Phat : 1 time returned to where I bought it for replacement within 10 days, 1 dead pixel
DS Lite : 2 times, 1 time returned to where I bought it for replacement within 10 days and 1 time to Nintendo within a year
DSi : 1 time returned to where I bought it for replacement within 10 days, 3 dead pixels
3DS : 1 time returned to where I bought it for replacement within 10 days, 8 dead pixel
All were device bought on launch day.
