LG Optimus 2X vs. Samsung Galaxy S2 (32GB) – Review

by Jerry D on February 21, 2011

Yes, so both the LG Optimus 2X and the newer Samsung Galaxy S2 are dual-core super-phones. But that doesn’t necessarily make this a fair fight. So we give LG’s phone a trident, arm Samsung’s handset with a small knife and urge them to fight it out in a gladiatorial battle of the specs…

XXXX versus graphic LG Optimus 2X vs. Samsung Galaxy S2 (32GB)   Review XXXX


The twin-engined Optimus 2X is a 3G/HSDPA (10.2Mbps) phone with added 802.11b/g/n Wi-Fi and Bluetooth 2.1 with A2DP. This 32GB Galaxy S2, meanwhile, features 3G/HSDPA/HSPA+ (21Mbps), 802.11b/g/n Wi-Fi and Bluetooth 3.0+HS. Whoosh! (where available) (0-1)

Size & Weight:

Compare the two phones on paper and the Galaxy S2 is slightly skinnier than the Optimus 2X with a chassis that’s only 8.49mm thick. Mmmm… But perhaps this is why the Galaxy S2 is slightly wider, measuring 66.1mm to the Optimus 2X’s 63.2mm.

Weigh the two phones (any set of digital kitchen scales will do…) and the Optimus 2X weighs 139g, while the Samsung Galaxy S2 (32GB) is a lightweight 116g. I know which one I’d prefer to carry around. (0-2)



In terms of imaging and video, the Optimus 2X’s 8.0 MP lens features a maximum resolution of 3264 x 2448 pixels and boasts features that include: autofocus, an LED flash, geo-tagging and Full HD/1080p video recording. There’s also a front-facing camera for video calls.

It’s a good spec. But the Samsung Galaxy S2 matches its opponent with a 8.0 Megapixel camera of its own, as well as autofocus, an LED flash, geo-tagging, touch focus functionality, face/smile detection, image stabilization and 1080p video capture. A extra camera on the front is designed for video calling. This round ends in a tie. (0-2)


Headlining the LG Optimus 2X is a 4.0-inch touch-sensitive LCD display with a standard resolution of 480 x 800 pixels. It has 384000 pixels onscreen overall, which works out at 233.25 pixels per inch.

In comparison, the Galaxy S2 packs a touch-sensitive Super AMOLED Plus screen that’s 4.27 inches wide and reinforced with Gorilla Glass. There’s no difference in the resolution. With 384000 pixels on the bigger screen, the pixel density is lower at 218.501 pixels per inch. But the superior screen technology more than wins this round for Samsung. (0-3)


How fast are these two handsets? Lift up the hood and the Galaxy S2 uses Samsung’s own dual-core Exynos processor, rated at 1GHz. The Optimus 2X’s engine is a 1GHz NVIDIA Tegra 2, featuring a dual-core ARM Cortex A9 processor and GeForce graphics. (0-3)


LG uses Android 2.2 (Froyo) on the Optimus 2X, which will be upgradeable to 2.3 (Gingerbread) in the future. Samsung ups the ante by using Google’s Android 2.3 at launch, customised with the company’s TouchWiz UI and Swype text input. (0-4)


This Galaxy S2 handset incorporates 32GB (a 16GB version is also available) versus the 8GB capacity of the Optimus 2X. Of course, the Optimus 2X also boasts an expansion slot to increase the maximum capacity to 40GB. A microSD slot on the Galaxy S2 further boosts the overall memory on Samsung’s phone to a whopping 64GB. Wow. (0-5)


The Optimus 2X also includes GPS/A-GPS, DLNA content sharing, HD (720p) TV-out via HDMI, a digital compass and a gyro-sensor.

In comparison, the Galaxy S2 piles on the extras, including: GPS/A-GPS, DLNA content sharing, Wi-Fi direct, a stereo FM radio (with RDS), optional NFC support, a digital compass, a gyroscope and an HDMI port. It also features four software ‘hubs’ – the Reader’s Hub, the Social Hub, the Games Hub and the Music Hub. (0-6)

The Samsung Galaxy S2 (32GB) wins!

The Samsung Galaxy S2 shows just what a powerful phone it is by shutting out the LG Optimus 2X in this fight.

The only disappointment with its specification is the 480 x 800 pixel resolution, which doesn’t get close to the iPhone 4′s excellent Retina display (640 x 960 pixels) or the qHD (540 x 960 pixel) display built into the Motorola Atrix 4G. Still, that Super AMOLED Plus technology looks awesome…

See if these two phones make our Top 20 Best Smartphones list…
