Android 2.2 vs Android 2.3

Android 2.3 (more popularly known as Gingerbread) is the successor to Android 2.2 which is also known as Froyo. One of the most anticipated improvements in Android 2.3 is the implementation of system-wide copy/paste functions. Many other smartphone operating systems have had problems in how to implement this feature just as you would have it in a computer. Another major shift in the OS is the shift in file system from YAFFS to ext4. The file system is responsible for managing how the files are written onto storage media like internal memory and memory cards. This is of little concern to users, though, as only programs interface with the file system.

In terms of improvements, Android 2.3 has extended its library of supported sensors. While Android 2.2 had the expected sensors like proximity, ambient light, and accelerometer, Android 2.3 adds the gyroscope, barometer, and many others. This extends the possibilities of Android as the added sensors can be used as control mechanisms for games or as usable environmental sensors for other applications.

NFC, or Near-Field Communication, is one of the new features of Android 2.3. With it, any capable Android phone can function as an identity card and can be used in many applications; the most prominent nowadays being debit cards like those used in busses and trains. This feature sees great prospects in other unmanned POS devices like vending machines. Native support has also been added for multiple cameras on the same device. The benefits of having more than one camera, or two for most cases, is exhibited by new smartphones and tablets that are able to shoot stereoscopic or 3D images and videos.

Lastly, many changes have been done to the UI of Android 2.2. More important than the aesthetic changes to the UI, Android 2.3 presents an updated software keyboard for faster and easier typing. Music enthusiasts should also enjoy the addition of new sound effects that were not available in Android 2.2 including: reverb, equalization, bass boost, and headphone virtualization.
