CyanogenMod (pronounced /saɪ.'æn.oʊ.dʒɛn.mɒd/sigh-AN-oh-jen-mod) is an open source replacement firmware for smart phones and tablet computers based on the Android mobile operating system. It offers features and options not found in the official firmware distributed by vendors of these devices.
Features supported by CyanogenMod include native theming support, FLAC audio codec support, a large Access Point Name list, an OpenVPNclient, an enhanced reboot menu, support for Wi-Fi, Bluetooth, and USB tethering, CPU overclocking and other performance enhancements, soft buttons and other "tablet tweaks", toggles in the notification pull-down (such as Wi-Fi, Bluetooth and GPS), app permissions management, as well as other interface enhancements. According to its developers, CyanogenMod does not contain spyware or bloatware.[3][4] CyanogenMod is also stated to increase performance and reliability compared with official firmware releases.[5]
CyanogenMod is developed as free and open source software based on the official releases of Android by Google, with added original and third-party code.
Although only a subset of total CyanogenMod users elect to report their use of the firmware,[6] as of 24 August 2012, CyanogenMod has recorded over 3.1 million installs on a multitude of devices.
About
CyanogenMod (pronounced sigh-AN-oh-jen-mod), is a customized, aftermarket firmware distribution for several Android devices (See above for supported devices & how to install CyanogenMod on said devices). Based on the Android Open Source Project, CyanogenMod is designed to increase performance and reliability over Android-based ROMs released by vendors and carriers such as Google, T-Mobile, HTC, etc. CyanogenMod also offers a variety of features & enhancements that are not currently found in these versions of Android.
History and development
Soon after the introduction of the HTC Dream (named the "T-Mobile G1" in the United States) mobile phone in September 2008, a method was discovered to attain privileged control (termed "root access") within Android's Linux-based subsystem.[9] Having root access, combined with theopen source nature of the Android operating system, allowed the phone's stock firmware to be modified and re-installed onto the phone.
In the following year, several modified firmwares for the Dream were developed and distributed by Android enthusiasts. One, maintained by a developer named JesusFreke, quickly became popular among Dream owners. In August, 2009, JesusFreke stopped work on his firmware, and suggested users switch to a version of his ROM that had been further enhanced by developer Cyanogen (Steve Kondik) called "CyanogenMod".[10]
CyanogenMod quickly grew in popularity, and a small community of developers, called the CyanogenMod Team (and informally, "Team Douche"[11]) made contributions. Within a few months, the number of devices and features supported by CyanogenMod blossomed, and CyanogenMod quickly became one of the most popular Android firmware distributions.
Like many open source projects, CyanogenMod is developed using a distributed revision control system with the official repositories being hosted on GitHub.[12] Contributors submit new feature or bug fix changes using Google's source code review system, Gerrit.[13] Contributions may be tested by anyone, voted up or down by registered users, and ultimately accepted into the code by one of a handful of CyanogenMod developers.
A version of ADW.Launcher, an alternative launcher (home screen) for the Android operating system, became the default launcher onCyanogenmod 5.0.8. The launcher provides additional features not provided by the default Android launcher, including more customization abilities (including icon themes, effects, and behavior), the ability to backup and restore configuration settings, and other features.
