I'll bet you don't.

You may think you do, but that would be a very awkward position to
view a small LCD screen. If you really hold your phone flat, you must
also tilt your head at a 90 degree angle from your body to view the
screen. I doubt you do this.

Go play with an iPhone. I'm sure you will find this "concern" isn't
one at all. It will probably work intuitively and exactly as you
expect.

It may not be an accelerometer, but rather a simple pendulum with a
tiny weight on it. That would be the cheapest and least power intense
way of doing it. Why power an accelerometer if you only have to detect
which way is up?
