Electronics just dies, that's a fact of life. You were just hit by bad luck there.

Take simcards, for example. The things are produced by the millions, and they are done CHEAP. The mfg process is tuned so that acceptable amount of cards pass the tests, and also the life expectancy of the cards is not that long, thy are designed to last for a couple of years. Once in a while there's going to be a manufacturing defect that hits somebody and now it was just your bad luck to get one.
