Motorola Occam. Cleverly named after the Occam's Razor prinicple, this will obviously be a RAZR device. Like the Nexus devices, it was seen on the server traffic log of Android Police. By the way, Occam's Razor merely means that if there are two theories that make the same prediction, the more simple one is best. And what could be more simple than a Nexus device uncomplicated by any manufacturer's skin. So, the theory is that the Motorola Occam is a Nexus version of the Motorola RAZR M or perhaps the Motorola RAZR HD.
Another device, the Manta, runs Android 4.2 and is believed to be a tablet due to the lack of the 'mobile' name in the UA string. Manta is short for manta-ray which fits in perfectly with the code names for the Motorola XOOM tablet. Stingray was the Wi-Fi version of the tablet and Wingray was the variant for the tablet that uses the Verizon data network. On the other hand, the Google Nexus 7 had a code name of grouper, so this could be anything from a larger 10 inch Google Nexus tablet, to a Motorola Nexus tablet.
Hopefully, we won't have too much longer to find out the details about Android 4.2 and which models will be among the first to be powered by the next build of Android.
