Shortly after the release of the iPhone 4S comes Android’s answer to Apple’s latest launch, the Samsung Galaxy Nexus running on the newly revealed Android 4.0 Ice Cream Sandwich. It’s a killer combo that marks Samsung as a premier Android developer, and makes Android all the more competitive in the smartphone market. Motorola also had a major launch this week with the Droid RAZR, while LG’s DoublePlay delivers a dual-screen device for business and pleasure.

Samsung Galaxy Nexus

From a facial recognition unlocking mechanism to the integrated voice typing, the new Samsung Galaxy Nexus is full of futuristic features designed to push the envelope. The specs are pretty much as expected, with a 4.65” sAMOLED screen, a 1.2 MHz dual-core processor, a 5-megapixel rear-facing camera and 1GB of RAM. The 4G device has a curved display that’s quite attractive, measuring slightly thinner than the iPhone 4S at its slimmest point. With software becoming the most important aspect of any mobile device these days, the Galaxy Nexus runs Android’s latest version, 4.0 (or Ice Cream Sandwich). It’s a sexy new device that comes with Android’s most powerful OS, up to the challenge of taking on Apple’s newest smartphone.

Motorola Droid RAZR

Motorola isn’t one to be left out, unveiling the Droid RAZR at a joint event with Verizon on the same day the Samsung Galaxy Nexus came out. As far as Android devices go, thin is in, as the Droid RAZR measures even slimmer than the Galaxy Nexus at 7.1mm. Running Android Gingerbread, the RAZR doesn’t get the perks of Ice Cream Sandwich (though it’s likely to be updated), but it does have an 8-megapixel rear camera. The RAZR also boasts a 1.2 GHz processor, 1GB of RAM and a 4.3” super AMOLED advanced QHD display. The device will be available in early November for $299.99 with a new two-year commitment to Verizon.

LG DoublePlay

We first heard about the LG DoublePlay a few weeks back, and the latest T-Mobile offering has finally been officially announced. LG’s DoublePlay is built for multitasking, with two screens for performing various functions. The first display measures 3.5 inches, and the smaller screen shares keyboard space, measuring just 2 inches. Surf the web or play games on one screen, and check emails or text messages on the other. Running Android 2.3 Gingerbread, the DoublePlay has a single-core 1GHz processor with a 5-megapixel camera with LED flash, and 720p video recording. No word on the exact pricing of the DoublePlay, but it’s rumored to hit shelves on November 2 for $149 with a contract.
