The OnePlus One comes with CyanogenMod 11S out of the box, which is a spiced up version of CyanogenMod 11 with a few extra goodies including a very unique lockscreen. While the two-tone lockscreen does not include any special features, it does come with a built-in visualizer that is automatically activated while playing back music.
While most of the pre-installed apps on OnePlus One/CM11S were already found to work without any issues on other CyanogenMod running devices, the lockscreen has remained exclusive to the handset until now. Thanks to the hard work of XDA senior member M4rt1n94, users of CyanogenMod on other devices can now also enjoy the CM11S lockscreen.
Installing the lockscreen does not really require any hackery from the user and all they need to do is flash this ZIP file on their device in recovery mode. The mod has been confirmed to work on the Nexus 4, Nexus 5, the Galaxy Note 3 and a few other devices without any issues. The developer has also provided the original files, in case the user wants to revert back to the original Android lockscreen.
