Memory

The Galaxy S II has 1 GB of dedicated RAM (in either LPDDR or possibly DDR2/DDR3 by Samsung) and 16 GB of internal mass storage. Within the battery compartment there is an external microSD card slot.

Display

The Samsung Galaxy S II uses a 108.5 millimetres (4.3 in) WVGA Super AMOLED Plus capacitive touchscreen that is covered by Gorilla Glass

 with an oleophobic fingerprint-resistant coating. The display is an upgrade of its predecessor, and the "Plus" signifies that the display panel has done away with Pentile matrix to regular RGB matrix display which results in a 50% increase in sub-pixels. This translates to grain reduction and sharper images and text. In addition, Samsung have claimed that Super AMOLED Plus displays are 18% more power efficient than the older Super AMOLED displays. Some phones have display issues, with a few users reporting a "yellow tint" on the left bottom edge of the display when a neutral grey background is displayed.
The resolution of the display is 800x480 pixels.

Reception

Reviews of the Galaxy S II have been positive. Engadget gave the device a 9/10, calling it "the best Android smartphone yet" and "possibly the best smartphone, period." CNET UK gave the device a favorable review of 4.5/5 and described it as "one of the slimmest, lightest mobiles we've ever had the privilege to hold." TechRadar gave the device 5/5 stars and describes the devices as one that "set a new bar for smartphones in 2011." Pocketnow was "impressed" with the speed of the web browser. SlashGear states that the device "sets the benchmark for smartphones in general." GSMArena points out minor drawbacks such as an "all-plastic body" and the handset having "no dedicated camera key," but still calls the handset "absurdly powerful" and concluding "we just cannot see beyond the new Samsung flagship if we're to name the ultimate smartphone."

After slightly over one month since its debut, more than 1 million units of Samsung Galaxy S II were activated in South Korea. Worldwide, 3 million units were sold in 55 days. After over 85 days of its first release, Samsung has declared global shipments of over 5 million for Galaxy S II and 10 million after 5 months. Partially owing to strong sales of Samsung's Galaxy range of smartphones, Samsung overtook Apple in smartphone sales during Q3 2011, with a total market share of 23.8%, compared to Apple's 14.6%.

This is the second variant of this phone to come to AT&T (Model SGH-I727) but with a couple of changes. For one, the display is now the same 4.52 inch screen shared with the Sprint model. Additionally, the main feature for this update is the inclusion of an LTE radio, to coincide with AT&T's launch of its LTE network. However, to make this change it was required for the chipset to be swapped from the Exynos to the Qualcomm Snapdragon MSM8260, as the Exynos SoC does not support LTE (akin to a similar limitation made on the T-Mobile model) It was released the along with the also LTE-capable [HTC Vivid] on November 6, 2011.
