With a built-in light sensor, several touchscreen phones have the ability to adjust brightness levels according to its surroundings. This feature helps you automatically adjust the brightness level, as well as help save your battery life when necessary. Samsung has recently released updates for the Galaxy S II, fixing its issue concerning the automatic brightness control.

The updates also transformed Swype to be more responsive and fixed connectivity issues as well. You can now get the updates via Samsung Kies. The automatic brightness control seems like a really cool feature to have, it can become bothersome when you constantly have to change the lighting on your device with different surroundings.
