Today I discovered that taking pictures in bright sunlight with a camera phone is a very bad idea when the sun can easily glint off the display, so that you can see your own reflection better than the thing you're trying to photograph. And having a camera phone which will switch from front to rear cameras with a light swipe on the screen will result in many pictures of your own scowling face -- not that you could see it at the time, due to the aforementioned sun-glinting-problems.
Technology. Fun when it works.
