Here's the main selling point. The Nexus 4 already has the latest Android 4.2.2 Jelly Bean OS and it was the first device to ship with Android 4.2 back in November, along with the Nexus 10. Android 4.2.1 and 4.2.2 just brought some minor updates and bug fixes. We already wrote a lot about Android 4.1 and you can check out a full review of Android 4.1 here.
To be quite honest Android 4.2 Jelly Bean is pretty much the same as Android 4.1 Jelly Bean with some minor improvements, including a new Photo Sphere panorama mode, keyboard with gesture typing, lock screen improvements, improved notification power controls with on/off toggle state added with Android 4.2.2, support for Miracast Wireless Display, a couple of accessibility improvements, group messaging, daydream screensavers, new clock app and a couple of other minor updates that came with Android 4.2.1 and 4.2.2.
Although some might prefer custom skins like HTC Sense UI or Samsung’s TouchWiz UI, stock Android has an appeal of its own and we certainly like it.
