The LG Nexus 4 is among a handful of Android devices to receive a spate of Android 4.2.2 Jelly Bean custom ROMs in recent times, besides being one of the first few to have already received the official Android 4.2.2 firmware from Google. With due credit to Android Open Kang Project (AOKP) team, Google's flagship phone now gets the latest Jelly Bean firmware with highly-customisable features from a popular custom ROM that is built out of original Android Open Source Project (AOSP) release.

Although the new AOKP release does not include any major feature upgrades, it packs all the top features taken from its previous releases into a stable ROM for a seamless user experience.
