\center{Quick Facts}
\begin{itemize}
\item Website: replicant.us
\item Exists since September 2009
\item Currently based on LineageOS
\item Android versions:
\begin{itemize}
\item Replicant 6: Android 6, last security update: October 2017\cite{last-android-6-update}
\item Replicant 9: Android 9, work in progress\cite{porting-to-android-9}
\end{itemize}
\item Supports $\sim$ 10 devices (smartphones and tablets)
\item $\sim$ 2 full time equivalent contributors and a big community
\end{itemize}

Best effort: \\
Minimum feature set required to support a device:
}
\begin{itemize}
\item Display working and graphics fast enough
\item sound working
\item Be able to make calls
\item etc
\item GPS, Camera, and other non crucial hardware may not work, or work in later releases
\end{itemize}

\center{Freedom issues in supported devices}
\outputpicture{0.8}{i9300_hardware.png}
\begin{itemize}
\item The cellular network
\item The modem firmware
\item Other nonfree firmwares
\item Bootloaders and TrustZone
\item Upstream anti-feature and huge code base
\end{itemize}
\end{frame}

{
\begin{frame}
\center{Tablets without modem?}
\begin{itemize}
\item - The cellular network
\item - The modem firmware
\item Also possible to "disable" the modem on some devices.

\begin{frame}
\center{Freedom issues in LineageOS (without google play)}
\outputpicture{0.8}{i9300_hardware.png}
\begin{itemize}
\item + Modem control over the device (MSM7K) or shared memory
\item + Nonfree libraries (RIL backdoor, etc)
\item + Anti-features
\end{itemize}
\end{frame}
}
{
\begin{frame}
\center{Worst case with stock devices:}
\begin{itemize}
\item + Only the kernel is free software
\item + Users potentially locked out of their devices
\item + Many Anti-features or unwanted applications
\item $\rightarrow$ Remaining freedoms: The ability to install F-Droid or other applications
\end{itemize}

Along with the fact that there is way more surveillance nowadays... \\

\center{Why Android?}
\begin{itemize}
\item Advantages:
\begin{itemize}
\item GUI and applications adapted to big fingers
\item $\rightarrow$ run on devices that:
\begin{itemize}
\item lack keyboard
\item have capacitive touchscreen and no stylus
\item Have very small displays with very high number of pixel
\end{itemize}
\end{itemize}
\item Issues
\begin{itemize}
\item Part of the GNU/Linux software architecture is light years away: Package management and build system, Graphics, audio, etc
\item Huge unknown code from google
\item Meant to run proprietary software, not to empower users
\end{itemize}
\end{itemize}
\end{frame}
\begin{frame}
\center{Areas of work:}
\begin{itemize}
\item Porting to Android 9 and upstreaming and related graphics work (thanks to NLnet/NGI funding).
\item Soon: PinePhone (and maybe the Librem5 too)
\item New Replicant 6 release and fixing bugs:
\begin{itemize}
\item SIM cards not recognized
\item Graphics and application compatibility $\rightarrow$ Being fixed
\item F-Droid freedom issues
\item FSDG distributions and licensing issues (build system)
\item WebView and build system
\end{itemize}
\item Bootloaders (Galaxy SIII and Galaxy Note II: XBOOT)
\item Documentation, presentations, etc
\item Infrastructure
\end{itemize}
