'''Replicant''' is a [[free (software)|free]] and [[open source]] [[operating system]] based on the [[Android (operating system)|Android]] mobile platform, which aims to replace all [[Proprietary software|proprietary]] Android components with their [[free software]] counterparts. This also makes it a [[security focused operating system]] as it closes discovered Android [[backdoor (computing)|backdoor]]s. It is available for several [[smartphone]]s and [[tablet computer]]s.

The name ''Replicant'' is drawn from the fictional [[replicant]] [[Android (robot)|androids]] in the ''[[Blade Runner]]'' movie. Replicant is sponsored and supported by the [[Free Software Foundation]].

== History ==
The Replicant project started in mid-2010 with an effort to consolidate various initiatives attempting to produce a fully [[free-as-in-freedom]] [[Android (operating system)|Android]] derivative for the [[HTC Dream]]. The original team consisted of [[Bradley M. Kuhn]], Aaron Williamson, Graziano Sorbaioli and Denis ‘GNUtoo’ Carikli. The project quickly led to the writing of replacement code for the non-free parts that were required to make the HTC Dream functional. The first component to be replaced permitted audio to work without a proprietary library. Replicant originally provided its own FOSS application repository, which was later replaced by [[F-Droid]].

The software that was in charge of handling the communication with the modem (which is called [[Radio Interface Layer]] – RIL) was then replaced by free code, thus making the telephony part usable. A library handling the GPS was then adapted from free code that was originally written for another phone and permitted the [[HTC Dream]] to have GPS working with Replicant.

Early versions of Replicant were based on the [[Android Open Source Project]] code, while versions 2.2 (April 2011) and later use [[CyanogenMod]] as their base, in order to make supporting more devices easier.

As development continued, many members of the original Replicant team retired from the project, making Denis "GNUtoo" Carikli the only remaining member from the original team still actively working on the project. In April 2011, Paul Kocialkowski decided to get involved with the project and gradually became the main Replicant developer, after successfully porting it to the Nexus S and Galaxy S devices.

Replicant is sponsored and supported by the Free Software Foundation.

=== Releases ===

== Security ==
See also|Security focused operating systems

In March 2014, Replicant developers found and closed a [[backdoor (computing)|backdoor]] present in a wide range of [[Samsung Galaxy]] products that allows the baseband processor to read and write the device's storage, sometimes with normal user privileges and sometimes as the [[root user]] depending on device model. It is unknown whether Samsung's proprietary firmware for the radio chip can be remotely instructed to use these access features and whether the vulnerability was introduced with legitimate uses in mind.

== Anchor|SDKDevelopment ==
On January 3, 2013, the project released Replicant 4.0 [[Software development kit|SDK]] as a fully libre replacement to [[Android SDK]].

== Supported devices ==
Scope of the Replicant project has been gradually expanded to include support for new devices, starting with the [[Nexus One]], [[Nexus S]] and [[Galaxy S]]. Replicant developers are continually working to add support for new devices. As of January 2014, the following devices are supported, with [[Wi-Fi]] and [[Bluetooth]] requiring proprietary [[firmware]] in order to work:
