This is what happens when you have no idea how your devices work:

Update: Speaking of the iPhone, I've spent a year annoyed by the fact that I couldn't get the screen to go horizontal and vertical on command. Then someone explained to me that the phone doesn't change unless it's held perpendicular to the ground. And sure enough, when I hold it straight up and turn it, it flips every time. I'd estimate this has generated a 10 percent improvement in my quality of life.
