Android 2.3 Gingerbread

Android 2.3 Gingerbread is a previous version of the Android mobile operating system. It was released in December of 2010, and is still today the most popular version of Android, and most popular mobile operating system in the world. It currently runs on 53.9% of all Android devices. The percentage has been shrinking since newer versions of Android have come out, but it still remains the most popular version.

Android "Gingerbread" is a codename of the Android mobile operating system developed by Google and released in December 2010, for versions that are no longer supported. The Gingerbread release introduced support for near field communication (NFC)—used in mobile payment solutions—and Session Initiation Protocol (SIP)—used in VoIP internet telephony. Gingerbread's user interface was refined in many ways, making it easier to master, faster to use, and more power-efficient. A simplified color scheme with a black background gave vividness and contrast to the notification bar, menus, and other user interface components. Improvements in menus and settings resulted in easier navigation and system control. The Nexus S smartphone, released in 2010, was the first phone from the Google Nexus line that ran Gingerbread, and also the first one from the line with built-in NFC functionality. Gingerbread uses version 2.6.35 of the Linux kernel. As of July 6, 2017, statistics issued by Google indicate that 0.7% of all Android devices accessing Google Play run Gingerbread.
