Another device is now added to the list of dev community supported when it comes to Android 5.1. Once again the dev community beats Google to the punch. The Nexus 4 has also received its own Rom of 5.1. This rom is an unofficial build and some bugs should be expected. This rom is reported to be working well. The gapps that are included are not working properly, but if you flash the PAGapps along with the rom those seem to be working. Users are reporting a nice and smooth experience. Head to the link below for the download.
