CyanogenMod

CyanogenMod was an open-source custom firmware for Android smartphones and tablets, created by a community of developers. It replaced the device’s original operating system with a version that offered more control, customization, and enhancements like improved performance and additional features. Users could install CyanogenMod to extend the life of older devices or to get a more personalized experience. It was popular for its flexibility and open nature before being discontinued in 2016, with the project’s team shifting focus to commercial ventures under the name LineageOS.
