The Samsung Galaxy S II GT-i9100 (or Galaxy S2, Korean : 삼성 갤럭시 에스 투) is an Android smartphone that was announced by Samsung on February 13, 2011 at the Mobile World Congress.[5]. It is currently the world's second thinnest Dual-Core smartphone (only behind the Japanese NEC Medias N-04C).[6] The Galaxy S II is the successor to the Samsung Galaxy S.

The Galaxy S II features a 1.2 GHz dual-core "Exynos" System on a chip (SoC) processor. It also features 1 GB of RAM, a 10.8 cm (4.3 in) WVGA Super AMOLED plus display and an 8 megapixel camera with flash that can record videos in full high definition 1080p. It is one of the first devices to offer a Mobile High-definition Link (MHL),[7] which allows up to 1080p uncompressed video output with HDMI while charging the device at the same time. Support for the USB On-The-Go (USB OTG) function was also specified and confirmed on this device.[8][9][8][10]

Launch

The Galaxy S II was given worldwide release dates starting from May 2011, by more than 140 vendors in some 120 countries.[11]

Both South Korea and United Kingdom (UK) were the first markets to receive this device.

On May 9, 2011, Samsung announced that they had received pre-orders for 3 million Galaxy S II units globally.[12]

Most regions have received or are still scheduled to receive the Galaxy S II 'GT-i9100' model. Samsung have also announced the release of a Tegra 2 SoC powered 'GT-i9103' version in the name of the Samsung Galaxy R (or 'Galaxy Z' in Sweden). The variant release of the Galaxy R 'GT-i9103' seems to corroborate the previous news of an Nvidia Tegra 2 powered Galaxy S II smartphone.[13][14] According to Eldar Murtazin, of Mobile-Review.com, this is believed to be because Samsung is not able to meet worldwide shipment demands of both its own Exynos chip and Super AMOLED Plus screens. He noted that nobody expected the "huge success" and "sky high" demand for the previous Samsung Galaxy S.[15] Eldar's belief seems to imply continued Product proliferation practices by Samsung.

In the UK, Phones4U was the first retailer to have exclusive rights to release the device earlier than others. Initially the first UK release currently shipped without the NFC capability (hinted possibly due to weight) but this is due to change with a later re-release of the same device with the NFC capability available.[16][17]

In India, customers were able to pre-order the Galaxy S II online from May 26, 2011. The phone was scheduled to be available at retail stores from June 9, 2011. Samsung has partnered with Vodafone to launch its phone at a cost of ₹32,850. Vodafone customers buying the device will also avail 1GB of free 3G data for the first six months.[18] The Exynos powered version sold in India currently has no NFC feature. As of August 2011, the Galaxy S II is priced at ₹29,199 (HomeShop18).

In Iraq the Galaxy S II 'GT-i9100', was released in Baghdad on July 18, 2011, by Jibal Company.

In Pakistan the Galaxy S II 'GT-i9100' was launched officially on 23rd of July 2011.[19]

In North America, Canada has been first to receive this device, from launch, at the end of July 2011 on Bell Mobility.[20][21] There are also planned releases in Canada for Virgin Mobile and SaskTel.[22] On July 20, 2011, Samsung's divisional chief, Shin Jong-kyun, announced that a release for the United States is to be expected "sometime in August".[23] For the U.S. release, multiple variant names prescribed by each mobile carrier are expected. The version released on Sprint will be called the Samsung 'EPIC 4G Touch' and on AT&T and T-Mobile USA it will be simply called 'Galaxy S II'.[24] Verizon will not have the Samsung Galaxy S II on their future lineup and instead will offer customers another phone, the Droid Charge. [25]

Hardware

Processor

The Galaxy S II has a 1.2 GHz dual core ARM Cortex-A9 processor running Samsung's Exynos 4210 System on a chip (SoC).

Samsung's Exynos 4210 SoC was the source of much speculation concerning another branded successor to the previous "Hummingbird" single-core SoC of the Samsung Galaxy S. Previously code-named "Orion", the Exynos 4210 uses ARM's Mali-400 MP for its GPU.[2][26] This graphics GPU supplied by ARM is a move away from the previously used PowerVR GPU contained in the first Samsung Galaxy S.[27]

The Exynos 4210 features support for ARM's SIMD engine (also known as Media Processing Engine, or 'NEON' instructions) and this may have a significant performance advantage in critical performance situations such as accelerated decoding for many multimedia codecs and formats (e.g., On2's VP6/7/8 or Real formats).[28][29][30]

At the 2011 Game Developers Conference, ARM's representatives were able to demonstrate playback in stereoscopic 3D on their Mali-400 MP at a 60 Hz framerate running on the same Exynos SoC. They then further stated that an increased framerate of 70 Hz would be possible through the use of HDMI 1.4 port.[26]

Memory

The Galaxy S II features 1 GB of dedicated RAM (in either LPDDR or possibly DDR2/DDR3 by Samsung) and has 16 GB of internal storage. It is not certain whether Samsung will manufacture the 32 GB versions due to higher costs. However, the official Galaxy S II website still shows the 32 GB version as well as the 16 GB version.[8] Within the battery compartment of the device, there is an external microSD card slot that can support up to 32 GB of additional storage.[8][31][32]

Display

The Samsung Galaxy S II uses a 108.5-millimetre (4.27 in)[8] WVGA Super AMOLED Plus capacitive touchscreen which is covered by Gorilla Glass that has a oleophobic coating to resist fingerprints. 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.[33]

Audio

The Galaxy S II uses audio hardware manufactured and branded by Yamaha.[34] The Galaxy S II's predecessor, the original Galaxy S, used Wolfson's WM8994 DAC.[35] Some reviewers and online forum users of both phones have declared that the Wolfson chip has a superior sound quality to that of the Yamaha's in comparison.[34]

Camera

On the back of the device is an 8-megapixel camera with single LED flash that can record videos in full high-definition 1080p at 30 frames per second. There is also a fixed focus front-facing 2-megapixel camera for video calling, taking photos as well as general video recording, with a maximum resolution of VGA (640 X 480).

Connectivity

The Galaxy S II is one of the earliest Android devices to natively support NFC.[36] This follows on from the Google Nexus S which was the first de-facto NFC smartphone device.[37] However, it has been reported that the UK version will be supplied without an NFC chip at the beginning of its production run[38] but Samsung will launch an NFC-equipped version later in 2011.[39]

Samsung has also included a new high-definition connection technology called Mobile High-definition Link (MHL). MHL has been noted as being "connection agnostic" in that it can use virtually any interface connection, such as those of HDMI or USB, for sending high-definition uncompressed 1080p video and audio from a mobile device. The main specialty of MHL is that it is optimized for mobile devices by allowing the device's battery to be charged while at the same time playing back multimedia content. For the Galaxy S II, the standard Micro USB port found on the bottom of the device can be used with an MHL connector for an HDMI connection to an external display such as a high definition television.[40] The mobile device can then draw power from the external display but can only do this for MHL-supported displays. Currently there are no MHL-supported televisions available on the market but this is expected to change by Q4 2011. On the side of the MHL connector is also standard charger input to still supplement battery charging of the device while outputting video.[7][41]

The micro USB port supports USB On-The-Go (USB OTG) standard which means the Galaxy S II can act as a 'host' device in the same way as a desktop computer in allowing external usb devices to be plugged in and used.[9] These external usb devices typically include USB flash drives and separately powered external hard drives. According to a recent video demonstration on YouTube[42], the OTG function was shown to be readily available with an ordinary Micro USB (B-type) OTG adaptor. The same YouTube video goes onto mention a successful test completed on a 2 TB USB external hard drive (dependent on own power) and also reports of success when connecting certain USB keyboards, USB mice, USB game pads. Currently the only file-system supported for USB drives within OTG is Fat32.

A standard 3.5 mm TRS headphone jack is available and is located on the top-side of the device. The Micro USB connection port is located on the bottom-side of the device.

BCM4330 combo chip integrates 802.11n Wi-Fi, Bluetooth 4.0 + HS and FM radio. BCM4330 supports Wi-Fi Direct that communicate directly with one another without having to interact with an access point. [43]

Accessories (optional)

Software

Android 2.3

The Galaxy S II ships with Android 2.3.3 (Gingerbread) installed.

The Sprint Galaxy S II variant (Epic 4G Touch) will ship with Android 2.3.4 (Gingerbread) installed as per the specs on the official Sprint Epic 4G Touch site.[44]

User interface

The phone employs the latest proprietary Samsung TouchWiz 4.0 user interface. It follows the same principle as TouchWiz 3.0 found on the previous Galaxy but adds new improvements. It also has a new gesture based interaction with the web browser which allows for zooming in and out of a webpage by pressing on the screen with two fingers and moving the device back and forth in a cradle-like movement. This is testament to the Gyroscope and accelerometer[45] used within this device. There have been improvements to the widgets drawer and layout in how many widgets can be added and how they are presented. Additionally there is new optional gesture-based control on TouchWiz 4.0 for the movement of widgets between screens, by allowing the device to be held and moved from side to side to scroll through home screens. This gesture-based management of widgets is a new optional method next to the existing method of holding and swiping between home screens.[46]

Bundled applications

Four new Samsung 'Hub' applications were revealed at the 2011 Mobile World Congress:

Social Hub
Which integrates popular social networking services like Facebook and Twitter into one place rather than in separate applications.
Readers Hub
This hub provides the ability to access, read and download online newspapers, ebooks and magazines from a worldwide selection.
Music Hub
An application store for downloading and purchasing music tracks on the device. Samsung has teamed up with 7digital to offer this service.[47]
Game Hub
An application store for downloading and purchasing games. Samsung has teamed up with partners including Gameloft to offer this service.[47]
Other applications
More applications include Kies 2.0, Kies Air,[48] AllShare (for DLNA), Voice Recognition, Google Voice Translation,[49] Google Maps with Latitude, Places, Navigation (beta) and Lost Phone Management, Adobe Flash 10.2, QuickOffice application and 'QuickType' by SWYPE.

Before launch, it was announced that Samsung had taken steps to incorporate Enterprise software for business users, which included On Device Encryption, Cisco’s AnyConnect VPN, MDM (Mobile Device Management), Cisco WebEx, Juniper,[36] and secure remote device management from Sybase.[50]

Cisco’s AnyConnect VPN for Samsung devices is now currently available on Android Market.[51]

As of May 2011 the device's firmware does not seem to include any of the enterprise features mentioned above.

Media support

The Galaxy S II comes with support for many multimedia file formats and codecs. For audio it supports (FLAC, WAV, Vorbis, MP3, AAC, AAC+, eAAC+, WMA, AMR-NB, AMR-WB, MID, AC3, XMF). For video formats and codecs it supports (MPEG-4, H.264, H.263, DivX HD/XviD, VC-1) and video formats (3GP (MPEG-4), WMV (ASF) as well as AVI (DivX)).

Continued support for the MKV format container was confirmed.[52][53] Furthermore, there is also continued native playback support for the Sorenson codec within FLV.[54] Neither 'MKV', 'FLV' or 'Sorenson' are listed within any available specifications as this was the case done for the previous Galaxy S. Up to 1080p HD video playback is supported on this device.

Community Support

It was public news that Samsung sent a number of Galaxy S II devices to four developers of the CyanogenMod project, with the only request from Samsung being to bring full support of CyanogenMod to the device.[55][56]

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."[57] 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."[58] TechRadar gave the device 5/5 stars and describes the devices as one that "set a new bar for smartphones in 2011."[59] Pocketnow was "impressed" with the speed of the web browser.[60] SlashGear states that the device "sets the benchmark for smartphones in general."[61] 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."[62]

After slightly over one month since its debut, more than 1 million units of Samsung Galaxy S II were activated in South Korea.[63] Worldwide, 3 million units were sold in 55 days.[64]. After over 85 days of its first release, Samsung has declared global shipments of over 5 million for Galaxy S II.[65]

Variants

Galaxy S II LTE

Announced on August 28th, 2011, the LTE version contains an upgraded 4.5 inch screen, a 1850 mAh lithium-ion battery, and an upgraded 1.5 GHz dual-core Snapdragon processor, as opposed to the 1.2Ghz Exynos processor. [66]

Galaxy S II Mini

There have also been reports of a Galaxy S II Mini, which would be an alternative smaller version, much the same way as the HTC HD Mini was to the HTC HD2.[67]

Galaxy R (GT-i9103)

The Samsung Galaxy R is one of the currently available variants of the Galaxy S II. It was announced for releases first in Europe starting from the end of July 2011 with subsequent releases for worldwide. The Galaxy R is slightly smaller in overall size along with some notable "downgraded" features.[68] It's differing comparable features include a 4.2" Super CLEAR LCD (SC-LCD) capacitive touchscreen display, a 5 megapixel camera with 720p HD video recording, 16GB internal storage and a microSD memory card slot. The overall physical size and back of the design of this device differ slightly to that of the original Galaxy S II. Like Galaxy S II, the Galaxy R will also support Kies Air (PC Suite via Wi-Fi).[69][70]
