Nexus 4 Android 4.3 Jelly Bean update appears
Android 4.3 Jelly Bean has leaked on the Nexus 4 with a system dump available to download now
Android 4.3 has leaked for the Nexus 4 as a backup file.
The leak appeared on XDA developers and is available to download and install right from there.
Jeff Williams posted a screenshot of his Nexus 4's About phone on Google+ demonstrating it was running Android 4.3.
Williams claims to have bought the Nexus 4 from Craigslist from 'a Googler' and was expecting it to be running Android 4.2.2 but then checked and it was running build number JWR66N - the Android build number known to be Android 4.3 Jelly Bean.
The conversation continues in the comments, with one Google+ user suggesting it was a flashed leaked ROM. Another user then chimed in to confirm the version was in fact the real deal.
The version system dump is now available to download via this Dropbox link (minus radio and bootloader according to Android Police) although as is always the case with unofficial updates, only try and download and install the update if you're comfortable rooting your device. If you are not sure how to do this safely, it's probably best you wait until the official version is rolled out.
Google is holding an event on July 24 that hints at the launch of Android 4.3 and the next-generation Nexus 7, so there's only a week or so to wait until you can get your hands on the official build anyway.
The root of Android 4.3 has been released before, but for the Samsung Galaxy S3 and again, this is the unofficial version and may not be 100 per cent finished.
Android 4.3 is said to bring some of the features of the Samsung Galaxy S4 and HTC one Google Edition to all Android devices, including a new camera UI, re-worked font, Bluetooth 4 low-energy support, improved graphics capabilities and new notifications.
