My wife's iPhone 4S has this really nasty looking discolored burn in the upper-right hand corner of her screen. She can't get rid of it. I'm tempted to buy a magnet and try to pull it out, but I fear damaging the phone. Not that she cares, really. Ever since iOS7 was released, and she noticed that most of the new features are Android copies (not to mention her phone runs like crap now), she's getting a Galaxy S4. But you're right. This myth of superior Apple build quality has got to stop. It's physically impossible, and has been proven to be impossible more times than I care to remember. Count the class-action lawsuits. There's a ton of them.
Nice anecdote. My 4S runs great and has no imperfections.
As for lawsuits, that doesn't mean anything. Lawyers can make cases with little evidence or truth.
