My Samsung was haunted by chip problem just days after purchase. I sent to Samsung repairing center and they replaced the motherboard for me. I downloaded the EMMC brickbug check app amd checked my new chip and I surprisingly discovered that the date of my chip is 1997, so many years before Samsung s3 came out. So I am worried that they may give me an insane chip again. And another thing, when I used that app to check for my original chip, it said its a sane chip. So does this app really work?
