Sometimes there's a little chip inside of the phone that controls the storage, and everything else. You can look for a close-up diagram of your phone to see what I'm talking about. Also, the quality of the phone depends on where you get it, how new it was, and how much you paid for it. Yes, I understand phones are expensive, but make sure you buy one that isn't ridiculously cheap. Like the saying, "You get what you pay for." I hope this helps.
