LineageOSLineageOS is an Android-based operating system for smartphones, tablet computers, and set-top boxes, with mostly free and open-source software. It is the successor to CyanogenMod, from which it was forked in December 2016, when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS. LineageOS was officially launched on 24 December 2016, with the source code available on both GitHub and GitLab.
Open Handset AllianceThe Open Handset Alliance (OHA) is a consortium of 84 firms to develop open standards for mobile devices. Member firms include HTC, Sony, Dell, Intel, Motorola, Qualcomm, Texas Instruments, Google, Samsung Electronics, LG Electronics, T-Mobile, Sprint Corporation (now merged with T-Mobile US), Nvidia, and Wind River Systems. The OHA was established on November 5, 2007, led by Google with 34 members, including mobile handset makers, application developers, some mobile network operators and chip makers.
Replicant (operating system)Replicant is a free operating system (OS) based on the Android mobile platform that intends to replace all proprietary Android components with free-software counterparts. It is available for several smartphones and tablet computers. It is written in the same programming languages as Android (from which it is forked indirectly). The modifications are mostly in the C language; the changes are mostly to the lower-level parts of the OS, such as the Linux kernel and drivers that use it.
Comparison of mobile operating systemsThis is a comparison on mobile operating systems. Only the latest versions are shown in the table below, even though older versions may still be marketed.
Mobile operating systemA mobile operating system is an operating system for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past.
Android (operating system)Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance, though its most widely used version is primarily developed by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
