The Infuse 4G and Galaxy S2 have common input features like Gorilla Glass display, multi-touch input, accelerometer sensor for UI auto-rotate, touch-sensitive controls, a proximity sensor for auto turn-off and Swype text input. But Infuse uses the TouchWiz 3.0 UI compared to Galaxy S2’s TouchWiz UI 4.0 along with a gyroscope sensor. Atrix on the other hand brings a biometric fingerprint reader, Gorilla Glass display, touch sensitive controls, MOTOBLUR UI with Live Widgets, multi-touch input, accelerometer sensor for UI auto-rotate and proximity sensor for auto turn-off.

Memory:
For sometime it looked like Atrix featured the biggest memory with 1 GB of RAM but with the introduction of Infuse 4G and Galaxy S2, which also feature 1 GB RAM, Atrix stands tied. And the internal storage to feature in Atrix 4G and Infuse 4G is 16 GB, while the Galaxy S2 will have 16GB and 32GB storage. All three smartphones will get microSD support up to 32 GB.

As Samsung’s Infuse and Motorola’s Atrix are going to AT&T, both these smartphones will end up with 14.4 Mbps HSDPA and 5.76 Mbps HSUPA as against T-Mobile Galaxy S2’s 21 Mbps HSDPA and 5.76 Mbps HSUPA.

WLAN/Bluetooth/ USB:
All of them have Wi-Fi 802.11 b/g/n with DLNA but Galaxy S2 has an added Wi-Fi Direct feature. The Atrix has Bluetooth version 2.1 with A2DP EDR, Infuse 4G with version 3.0 with A2DP and Galaxy S2 with version 3.0 plus HS. Also all of them have microUSB version 2.0 but the Galaxy S2 has microUSB (MHL).
