Full specifications for Google’s “Nexus Prime” smartphone have leaked onto the web in advance of an expected unveiling next Tuesday at Samsung’s Unpacked event in San Diego.

Possibly called the Samsung Galaxy Nexus, the phone is packing some seriously good features under the hood. The long-awaited Android 4.0 Ice Cream Sandwich operating system will debut on the 9mm thin device. Additional features include a 4.65-inch curved glass Super AMOLED HD display running at 1280x720 resolution, a TI OMAP 4460 dual-core Cortex A9 processor clocked at 1.2 GHz, 1GB of RAM, 32GB of on-board storage, a 5MP rear camera and a front 1.3MP shooter, 1080p video capture, LTE / HSPA support depending on carrier, Wi-Fi a/b/g/n, NFC technology and a 1,750 mAh battery.

BGR has also confirmed that the OS will be a pure Google device, meaning no fancy third-party UI or other modifications to ICS. Furthermore, they believe that the Galaxy Nexus will be a Verizon Wireless exclusive.

An unveiling couldn’t come at a better time in light of Apple’s lackluster iPhone 4S announcement a couple of days ago. Many consumers and even AT&T employees were anticipating a revolutionary iPhone 5 device, not the evolutionary handset that Cupertino unveiled instead.

When compared with the Galaxy Nexus specs, the 4S already looks a bit dated, at least in terms of sheer processing power and display. But if the Nexus is only launching on one US carrier, this could potentially hurt overall sales.
