Why Auto-Brightness on iPhone, Android is Awful

The auto brightness settings don't work so well on these so-called "smart" phones.

In a controlled environment, like your office, you can set the brightness of your display how you want it and it'll be good for most of the time (unless you're lucky enough to have an office with giant windows). Smartphones, on the other hand, are constantly in a state of travel and will be under various different light conditions, varying from pitch darkness when you're hiding under a cardboard box to when you're under the blasting rays of the sun. For this reason, automatic brightness is an important feature of smartphones.
