Recently, a spate of Android devices have been bestowed the privilege of enjoying the latest Android 4.2.2 custom firmware, with due credit to the release of Android Open Kang Project (AOKP) Build 4 custom ROM. Though the ROM does not include any major feature changes, it brings a bloatware free pure Android experience, as it is custom built out of original Android Open Source Project (AOSP) release.
