Swirling rumours about Google's next smartphone, its size and specs suggest that the Google Nexus 4G will run Android OS 4.0, codenamed Ice Cream Sandwich.

The Android 4.0 powered Nexus 4G, which already carries the nick name of the “beast", will reportedly feature a monster-sized 720p resolution screen, and the Ice Cream Sandwich operating software will bring 3D features and Open GL head tracking for facial expressions and sensing.

The list of Nexus 4G smartphone’s striking features will include a 1.2GHz or 1.5GHz dual-core processor, 1GB of RAM, 4G LTE connectivity, a front-facing camera for video chatting, a rear-facing 5-megapixel camera with 1080 video recording and playback capabilities.

Earlier, reports were claiming that the Nexus 4G will come equipped with NVIDIA’s quad-core chip.

With all those specs the Nexus 4G smartphone can really become an iPhone killer. Apple is believed to have deferred the release of its fifth-generation iPhone in an effort to deliver innovative software capabilities such as NFC-enabled mobile payment technology.
