The first Galaxy S smartphone was a shining example of Android at its best, so when the Samsung Galaxy S2 rocked up in 2011, we could not wait to see what the super slim successor had in store.
Joining the dual-core processing ranks alongside the Motorola Atrix and LG Optimus 2X, we wanted to know how the S2 shaped up against two of its closest rivals.
Is the Galaxy S2 worthy of a place on T3's list of the best mobile phones? We pit the three smartphones up against each other to find out where you should be spending your money.
Samsung Galaxy S2: At 8.5mm, it’s slender but feels a bit too lightweight. The plastic back belongs on a much cheaper handset.
Motorola Atrix: The design is uninspiring and looks chunky next to the Samsung S II. Build quality is the best here, though.
LG Optimus 2X: Slightly taller than the Motorola Atrix, the Optimus 2x shares its solid build and uninspiring style
Samsung Galaxy S2: Android 2.3.3 overlaid with Samsung’s TouchWiz UI 4.0 includes neat media hubs and plenty of widgets.
Motorola Atrix: Here you get Android 2.2 instead of 2.3, but with MotoBlur included it’s the best for social networkers.
LG Optimus 2X: The most outdated, with Android 2.2.1. It’s functional and pleasant enough to use, if a little dull.
Samsung Galaxy S2: The 4.2-inch Super AMOLED screen is gloriously bright, even though the resolution doesn’t match the Atrix.
Motorola Atrix: Off-angle viewing is good, but the four-inch, 960x540 screen doesn’t have the wow factor of the Samsung’s.
LG Optimus 2X: The four-inch 800x480 LCD is fine but can’t match the higher-res Atrix or the AMOLED splendour of the S II.
Samsung Galaxy S2: It’s fast, but not optimised for gaming in the same way as a Tegra-equipped phone.
Motorola Atrix: An Nvidia Tegra 2 processor makes it slightly nippier than the Samsung S II.
LG Optimus 2X: Shares the same Nvidia Tegra 2 processor as the Atrix and is just as speedy.
Samsung Galaxy S2: Eight-meg shots are excellent, with natural colours. 1080p video is tasty too.
Motorola Atrix: Only five megapixels and 720p videos. Stills can’t match the sharpness of rivals
LG Optimus 2X: Like the S II, you get 1080p video and sharp, if overly bright eight-megapixel stills.
Samsung Galaxy S2: 21Mbps HSDPA, N Wi-Fi and Bluetooth 3.0: it’s bang up to date. DLNA and Kies stream media to your PC, too.
Motorola Atrix:Regular connections include 10.2Mbps HSDPA, N Wi-Fi and Bluetooth 2.1, with USB and HDMI via its docks.
LG Optimus 2X: You get 10.1Mbps HSDPA, N Wi-Fi and Bluetooth, as well as DLNA, and an HDMI port for HDMI mirroring.
Samsung Galaxy S2: Build quality aside, the Galaxy S II is an outstanding phone. What really sets it apart are the exceptional screen and excellent eight-meg camera.
T3 Star rating: 5 out of 5
Motorola Atrix: The Atrix’s laptop and media docks make it unique. It’s no slouch as a phone, but its camera and screen can’t match the Galaxy S II.
T3 Star rating: 4 out of 5
LG Optimus 2X: With a fast Nvidia Tegra 2 chip this is a viable option for gaming fans, but as a phone it pales in comparison to the Galaxy S II and Atrix.
T3 Star rating: 3 out of 5
Samsung Galaxy S2: £499 (16GB)
Motorola Atrix: £499 (16GB)
LG Optimus 2X: £450
