You can enjoy latest and greatest Google OS ~ Android L on Nexus 5 and Nexus 7 (2013) officially. However, Google did not make an official one for older Nexus devices like Nexus 4. But the community had done it for all of us. Well, the Android L is a developer preview OS. Therefore, it should have bugs. Not to mention this Nexus 4 ROM which ported from it. It might have even more bugs flying around. However, if you happen to have CWM or TWRP installed on your Nexus 4, no harm to try it. Just make a backup first…
