Has Android 5.0 Key Lime Pie been spotted running on the Nexus 7 and Nexus 4?

It is known that the next major update to Google's mobile operating system will be dubbed Android 5.0 Key Lime Pie, with new system possibly arriving later this year, but the OS has already been spotted running on the new Nexus 7 tablet and the Nexus 4 smartphone.

The appearance was discovered in the Chromium bug tracker, which is Chrome's open source backbone.

Both the Nexus 7 and Nexus 4 devices were recently updated to Android 4.3 Jelly Bean. They come with the build numbers JSS15J and JWR66V respectively.

The ‘J’ at the start of the build number stands for Jelly Bean. But now some new build numbers for both devices have been spotted, with the Nexus 7 coming with KRS36B, and the Nexus 4 with KRS36B, with the the ‘K’ standing for Key Lime Pie.

There is nothing in Chromium bug tracker that sheds any more light on the commercial appearance of Android 5.0 Key Lime Pie, but Android fans will be encouraged that it is already being tested in some quarters.

Two high-profile Android Jelly Bean devices to have debuted in recent months, in the form of the Samsung Galaxy S4 and the HTC One.
