The Battle Of The Android Dual Core Superphones

The Motorola Atrix 4G vs Samsung Galaxy S II vs LG Optimus 3D is a battle of the new flagship Android devices and the new dual core processors.  All of these devices feature a 1 GHz dual core processor. The Atrix 4G features the NVIDIA Tegra 2, the Galaxy S II uses their own Samsung Exynos 4210, and the Optimus 3D has the TI OMAP 4.

Android Dual Core Superphones: Software

The Atrix 4G from Motorola is running a MotoBlur version of Android OS 2.2 (Froyo) but will be updated in the near future to Android OS 2.3 (Gingerbread). It features additional software that allows it to run its WebTop netbook dock and its Mozilla Firefox web interface, which is an advantage over all phones in the market today.

The Samsung Galaxy S II is shipping with Android 2.3 with an updated version of the TouchWiz 4.0 UI and comes with the Swype keyboard functionality built in. Samsung also has notable features in the form of integrated hubs; one for Readers, Social, Games and Media. The Galaxy S II also features enhanced business support with features from Cisco and Microsoft Exchange support.

When it comes to the LG Optimus 3D you get Froyo that will also be upgraded to Gingerbread in the near future with the addition of some enhanced 3D UI elements. A dedicated ‘3D’ Hot Key on the side of the handset can activate one of five 3D UIs, including: Gallery, Camera, Game & Apps, YouTube 3D and 3D Guide.

Dual Core Processor/ SoC (System-on-a-Chip)

All three designs are dual core and based off of the ARM Cortex-A9 architecture design. Performance will be more than adequate on all three, but each design will have inherent flaws and benefits.

The Atrix 4G features the Nvidia Tegra 2 chipset that everyone has been clamoring over recently and powers the highest resolution from the bunch, with a (540 x 960) qHD display. It is a speedy performer and has outperformed the Exynos from Samsung in recent comparison tests.

Samsung Galaxy S II and the Exynos 4220 dual core SoC use an in house design and adds to the performance of the previous speed leading Hummingbird design.

LG chose to go with the TI OMAP 4 in the Optimus 3D and it is the first implementation of the chipset in a smartphone, though it is also featured in the Blackberry Playbook. Recent benchmark testing has this SoC leading the pack in terms of performance, besting the otherwise identical Nvidia Tegra 2-powered LG Optimus 2X.

Screen Size & Clarity

The Motorola Atrix 4G comes with a smaller screen size at 4 inches, but features the highest resolution of the group with a 540 x 960 qHD display. It offers extreme clarity approaching the resolution of the iPhone 4’s Retina display, but takes a small hit in terms of 3D rendering due to the improved quality.

Samsung delivers the Galaxy S II with an upgrade to their Super AMOLED display and comes with Super AMOLED Plus, which increases the number of sub-pixels by 50 percent and makes the screen more visible in bright light.

LG features an LCD with a 480 x 800 resolution on 4.3 inch display. The LCD will not match the quality of the other displays but the autostereoscopic LCD is a world’s first on a mobile phone, supporting 3D viewing without glasses.

Both the Motorola and Samsung phones feature scratch resistant Gorilla Glass which has proved to valuable in protecting the phone’s greatest asset.

Storage And Memory

The Galaxy S II wins out in terms of capacity as it comes in either a 16 GB  version or 32 GB variant. It also has 512 MB of RAM. The Atrix only comes in one version featuring 16 GB of on-board storage, but has the advantage with its 1 GB of RAM. The Optimus 3D is the loser here with only 8 GB of built in  storage and 512 MB of RAM.

All phones have a microSD slot capable of adding an additional 32 GB of storage if necessary.


In terms of camera support the LG Optimus 3D is the clear winner with its dual rear cameras and ability to shoot 3D video in 720p and 1080p in 2D.

The Galaxy S II features an 8 megapixel shooter capable of autofocus, LED flash, geo-tagging, touch focus functionality, face/smile detection, image stabilisation and 1080p video capture.

While the Atrix 4G has a 5 megapixel rear camera capable of 720p recording. All of the phones feature front-facing cameras a have support for video calling.


It terms of size the Galaxy S II is the clear winner, coming in at 8.49 mm. It is now the world’s thinnest smartphone, besting the Apple iPhone 4 and the Sony Ericsson Xperia Arc. The LG is the largest of the group at 11.9 mm, but it gets leeway due to the use of two rear cameras and its 3D capabilities. Coming in at 10.1 mm, the Atrix 4G sits squarely in the middle of the pack.

Battery Life

While none of the devices have been thoroughly battery life-tested, the Atrix 4G wins out because it is fitted with a large 1930 mAh battery and should feature stellar battery life. The Galaxy S II features a more than acceptable 1650 mAh battery, while the Optimus 3D makes do with a now standard 1600 mAh battery.

Android Dual Core Superphone Leader

The dual core battle is getting heated with almost all manufacturers and chip producers in the game expect for HTC and Qualcomm, who still have yet to release a dual core product. In terms of the Motorola Atrix 4G vs Samsung Galaxy S II vs LG Optimus 3D, all of the devices are stellar performers and each has their own advantage.

The Atrix 4G has the ability to connect to a WebTop dock, giving it new functionality never before seen on a smartphone, and features the new qHD high-resolution display. The Galaxy S II is the world’s thinnest smartphone and comes with a beautiful Super AMOLED Plus display. The Optimus 3D obviously features the unprecedented ability of being the world’s first 3D capable smartphone.

As you can see there really is no clear winner in this comparison and whichever of these devices you get, consider yourself on top of the Android mountain at least for right now. We would like to hear how you guys weigh in and which device is on top of your personal best list.
