In this video we compare the software of the Nexus One with the Nexus S. They’re running different versions of Android, so we get to see how 2.2 and 2.3 are different. To the end user, not much has changed between the two versions of Android. Most changes for Android 2.3 occur under the hood like concurrent garbage collection, support for gyroscopes and even barometers, NFC support, and native support for a front-facing camera. Some visual effects are improved, such as the program tray animation, plus there’s use of more green, checkboxes are spruced up, and the keyboard looks different (though we weren’t able to clock faster text entry speeds with the Gingerbread keyboard). In terms of system speed, 2.3 seems to be about 10% faster than 2.2, which is less of a performance jump than we saw from 2.1 to 2.2.
