Sailfish OS has been ported to Google Nexus 4, and it can be installed either next to Android using MultiROM or to replace Android totally. Version Alpha 4 is still considered as an early adopters version, not everything works yet but it's quite usable already.

Important: Letter from the developers
We're happy to publish the fourth Early Adopter Release of Sailfish OS ( for Nexus 4 (mako) to you. We have also released the EA2 version of the Sailfish OS Hardware Adaptation Development Kit (HADK), as per earlier email. 
This installation image is for early adopters only, meaning we know that some things are not functional or perhaps even broken -- please see the release notes below. We are excited to get all of you properly included in the early stages of the project. Do note that this Sailfish OS image is strictly for personal and non commercial usage only. 
We've prepared a 'demo' version of the image which contains the kind of preinstalled 'marketing' content and the core apps used for demonstrations - this helps you quickly get a feel for all the interactions that are avalable on a device that has been used for a while but isn't really what you want for personal use. You can however cleanly remove the demo content. 
We want to build a community around Sailfish OS for Android devices that is based on mutual trust and respect for what we are all doing. Hence -- we ask that whenever you do screenshots, videos, forum or blog posts (and we're happy if you do!) or the like, you emphasise that this is work-in-progress and not a productised release. It is important for Jolla that correct expectations are set for those who might be users of the final product -- and that they understand what they see is not a released product. If you do demo videos, take advantage of our new 'demo content' image (check availability for your device) that has pre-set contacts/imagery/messages/etc to show full functionality of Sailfish OS. 
WARNING: Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hearing loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with this project is responsible for your actions but yourself. Good luck. 
NOTE: You will lose your on-device data (including /sdcard), so make a proper backup and make sure to copy that backup to your PC.* 
NOTE: Make sure to read all the release notes below. Please DO NOT contact Jolla Care nor Developer Care for any issues encountered with this Early Adopters build, instead use the following communication channels: 
We will all meet in #sailfishos-porters (note, new location) on and please use us (thp, alterego, Stskeeps, lbt, sledges) to work together, report any bugs, graphical glitches or missing functionality that you find, which are not included in the release notes above. You can also find the hardware adaptation source code at . 
You are also welcome to participate in threads at about Nexus 4 and Sailfish OS as well as for more general Sailfish OS topics at
