The screenshots of the app running on a tablet revealed a debug icon in the shape of a slice of Key Lime Pie. The Jelly Bean version showed...a jelly bean, of course. Why no Kit Kat? Well, the deal with Nestle came out of nowhere and many departments at Mountain View were caught off guard. According to Google’s Director of Global Partnerships John Lagerling, most teams internally had already prepared for the next Android build to be Key Lime Pie.
Android 4.4 is expected to be introduced next month and that information was confirmed by none other than Nestle, producer of Kit Kat. If you believe that manufacturers drop clues about launch dates in the time that clocks are set to on an unreleased device, then you might see the 10:07 time set on the picture of the Android 4.4 debug icon to be a clue pointing to an October 7th release. We also hear that the next Android test builds no longer refer to the Google Nexus 4, but now mentions the Nexus 5.
