Earlier this month, Google released the Android L Developer Preview source code to the AOSP, which is available for Nexus devices such as Nexus 4, Nexus 5, Nexus 7 2012 Wi-Fi/LTE variants, Nexus 7 2013 Wi-Fi/LTE and the Nexus 10.
This indicates that Google's older Nexus devices will also get the Android L touch.
While the Android L Developer Preview is only available for the Nexus 5 codenamed Hammerhead and the Nexus 7 2013 Wi-Fi variant codenamed Flo, developers at XDA have managed to bring Google's latest Android software for the fourth generation Nexus smartphone codenamed Mako and the Wi-Fi model of the Nexus 7 2012 known as Grouper.
Senior XDA member, sykopompos, has successfully ported the Android L Developer Preview to the Nexus 4.
The developer has also shared a flashable zip file allowing Nexus 4 users to taste the Android L Developer Preview ahead of the official release. Navigate to the source thread to know more about the port.
