Las Vegas - AT&T unveiled two HSPA+ Android smartphones here at its developer's conference, where the carrier announced the Motorola Atrix with dual-core NVIDIA Tegra 2 processor and the Samsung Infuse with large 4.5-inch screen.
Pricing and availability weren't announced.
The Motorola Atrix features Android 2.2 OS, 1GHz Tegra processor, and 10.9mm depth.
The Samsung Infuse features 4.5-inch touchscreen using proprietary new Super AMOLED Plus display technology. It features 1.2GHz processor, Android 2.2, Samsung's TouchWiz interface, 8-megapixel HD camera/camcorder, and front-facing 1.3-megapixel camera.
LG will bring the Optimus 2X, the world's first smartphone with dual-core processor, to the U.S. around March as a 3G GSM/HSPA device, LG Electronics president/CTO Skott Ahn told TWICE.
Ahn declined to say whether the phone would operate on the T-Mobile or AT&T network, but the device features the 10.2/5.76Mbps HSPA technology used by both carriers.
He also said the company tomorrow would introduce its first tablet but declined to offer further details.
The Optimus 2X, an Android-based touchscreen smartphone, will also be the world's first phone to capture, store and play back video in full 1080p resolution, Ahn noted. If it becomes available in March, it will ship with Android 2.2 OS, and if it ships later, it will come out of the box with Android 2.3 (Gingerbread), he said.
The Optimus 2X features 1GHz NVIDIA Tegra 2 processor to speed up operations such as multitasking. It also comes with 4-inch 400x800 capacitive touchscreen, 8-megapixel camera/camcorder, front-facing 1.3-megapixel camera for video chat, Wi-Fi 802.11b/g/n, microUSB 2.0, and microSDHC card slot supporting 32GB cards.
Also at CES, the company unveiled another Android smartphone billed as offering the world's brightest smartphone display. The Optimus Black features proprietary Nova display with 700-nit brightness for outdoor visbility in strong sunlight, yet its more power efficient than conventional LCDs and AMOLED displays, the company contended.. The display also delivers pure white tones to make text reading easier, LG said.
The Optimus Black GSM/HSPA is only 0.36-inches-thick at its thickest point and tapers down to 0.24 inches at its thinnest point, making it the world's slimmest cellphone, the company also claimed.
Ahn said it's not certain yet when the phone will be available in the U.S., but a company statement said it would be rolled out globally in the first half with Android 2.2 but be upgradable to Android 2.3. It's also the world's first smartphone with Wi-Fi Direct capability for direct transfer of phone content to other mobile devices and PCs, and it also features the world's first front-facing 2-magapioxel camera for videochats.
A new user interface lets users directly access messages, emails and missed calls from the locked screen with just one single finger tap. The gesture UI lets users lift, shake or tap the phone to initiate various functions, such as taking pictures.
