Samsung unveiled the S II on 13 February 2011 at theMobile World Congress(MWC) in Barcelona.[6]It was one of the slimmest smartphones of the time, mostly 8.49 mm thick, except for two small bulges which take the maximum thickness of the phone to 9.91 mm.[7] The Galaxy S II has a 1.2 GHzdual-core"Exynos"system on a chip(SoC) processor,[8]1 GB ofRAM,a 10.8 cm (4.3 in)WVGASuper AMOLED Plusscreen display and an 8-megapixelcamera with flash and1080pfull high definition video recording. It is one of the first devices to offer aMobile High-definition Link(MHL),[9]which allows up to 1080puncompressed videooutput to an MHL enabled TV or to an MHL toHDMIadapter, while charging the device at the same time.USB On-The-Gois supported.[10][11]

The user-replaceable battery gives up to ten hours of heavy usage, or two days of lighter usage.[12]According to Samsung, the Galaxy S II is capable of providing 9 hours of talk time on 3G and 18.3 hours on 2G.[12][13]

The Galaxy S II was popular and a huge success both critically and commercially,[14][15]selling 3 million units within its first 55 days on the market.[16]It was succeeded by theSamsung Galaxy S IIIin May 2012.[17]

Release

edit

The Galaxy S II was given worldwide release dates starting from May 2011, by more than 140 vendors in some 120 countries.[18]On 9 May 2011, Samsung announced that they had received pre-orders for 3 million Galaxy S II units globally.[19]

Some time after the device's release, Samsung also released a variation of the phone known as theGalaxy R,which uses aNvidiaTegra 2chipset.[20][21] Another variant of the S II, called the Galaxy S II Touch Epic, was announced in August 2011 and was released on September that same year. The phone was available via Sprint, and has a bigger capacity battery than the original S II. It was heavier than the original S II, at 130g.

Samsung also reportedly shipped Galaxy S IIs for free, to several developers of the custom Android distributionCyanogenMod(particularly those who had maintained its ports for the Galaxy S with an intent for them to port CyanogenMod 7 to the device).[22]

Features

edit

Software and services

edit

The Galaxy S II was launched withAndroid 2.3 "Gingerbread".American variants began shipments with the slightly updated version 2.3.5 installed.[23][24]Version 2.3.6 was made globally available on 12 December 2011.[2][25]On 13 March 2012, Samsung began to roll out upgrades toAndroid 4.0.3 "Ice Cream Sandwich"[26]through their phone management softwareKIESto users in South Korea, Hungary, Poland and Sweden. Russian users received the update on 5 July 2012, while the rest of Europe received it on 1 August 2012.[27]In February 2013, Samsung began rolling out an update toAndroid 4.1.2 "Jelly Bean"for the device.[28]

The S II employs theTouchWiz4.0 user interface, following the same principle as TouchWiz 3.0 found on the Galaxy S, with new improvements, such ashardware acceleration.It also has an optionalgesture-based interaction called "motion" which (among other things) allows users to zoom in and out by placing two fingers on the screen and tilting the device towards and away from themselves to zoom in and out respectively. This gesture function works on both the web browser and the images in gallery[29]used within this device. "Panning" on TouchWiz 4.0 allows the movement of widgets and icons shortcuts 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.[30]The Android 4.1 updatebackportsthe TouchWiz Nature interface and other features from theGalaxy S III,such as Direct Call, Pop-up Play, Smart Stay, and Easy Mode.[28]

Four newSamsung Hubapplications were revealed at the 2011 MWC: Social Hub, which integrates popular social networking services into one place rather than in separate applications, Readers Hub, providing the ability to access, read and download online newspapers, ebooks and magazines from a worldwide selection, Music Hub (in partnership with7digital,[31]) an application store for downloading and purchasing music tracks on the device, and Game Hub (in partnership withGameloft,[31]) an application store for downloading and purchasing games. Additional applications includeKies 2.0,Kies Air,[32]AllShare (forDLNA), Voice Recognition, Google Voice Translation,[33]Google Mapswith Latitude, Places, Navigation (beta) and Lost Phone Management,Adobe Flash10.2,QuickOfficeapplication and 'QuickType' by SWYPE.

Before launch, it was announced that Samsung had taken steps to incorporateEnterprise softwarefor business users, which included On Device Encryption,Cisco’sAnyConnectVPN, device management, Cisco WebEx,Juniper,[34]and secure remote device management fromSybase.[35]

The Galaxy S II comes with support for many multimedia file formats and codecs. For audio it supportsFLAC,WAV,Vorbis,MP3,AAC,AAC+,eAAC+,WMA,AMR-NB,AMR-WB,MID,AC3,XMF.For video formats and codecs it supportsMPEG-4,H.264,H.263,DivX HD/XviD,VC-1,3GP(MPEG-4),WMV(ASF) as well asAVI(DivX)),MKV,FLVand theSorenson codec.For H.264 playback, the device natively supports 8-bit encodes along with up to 1080p HD video playback.[36][37][38]

Unofficially, the Galaxy S II can runAndroid 13"Tiramisu".[39]

Hardware and design

edit

Chipsets

edit
Dismantled Samsung Galaxy S II in black, from left to right components include the handset, battery and back cover

The Galaxy S II has a 1.2 GHzdual coreARM Cortex-A9processor that uses Samsung's own 'Exynos4210'System on a chip(SoC) that was previously code-named "Orion". The Exynos branded SoC was the source of much speculation concerning another branded successor to the previous "Hummingbird"single-core SoC of the Samsung Galaxy S. The Exynos 4 Dual 45 nm (previously Exynos 4210) usesARM's Mali-400 MPGPU.[40][41]This graphics GPU, supplied by ARM, is a move away from thePowerVRGPU of the Samsung Galaxy S.[42]

The Exynos 4210 supports ARM'sSIMDengine (also known asMedia Processing Engine,or 'NEON' instructions), and may give a significant performance advantage in critical performance situations such as accelerated decoding for many multimedia codecs and formats (e.g., On2'sVP6/7/8 orRealformats).[43][44][45]

The Mali 400 GPU in the Exynos 4210 SOC is one of the only, if not the only GPU powering Android devices, that does not support GL_RGB Framebuffer Objects (FBOs), only GL_RGBA. The newer Galaxy S II (9100G), based on the PowerVR SGX540, does not exhibit the issue.

At the 2011Game Developers ConferenceARM's representatives demonstrated 60 Hz framerate playback in stereoscopic 3D running on the same Mali-400 MP and Exynos SoC. They said that an increased framerate of 70 Hz would be possible through the use of anHDMI 1.4port.[41]

TheMotorola Atrixadvertised in June 2011 that it was "the world's most powerful smartphone"; in August 2011 the UKAdvertising Standards Authorityruled that the Atrix was not as powerful as Galaxy S II due to its faster processor.[46]

A newer Samsung Galaxy S II variant (i9100G) uses a 1.2 GHz dual core TI OMAP 4430 processor with PowerVR SGX540 graphics.[47]

Storage and RAM

edit

The Galaxy S II has 1 GB of dedicated RAM and up to 32 GB of internal mass storage. Within the battery compartment there is an externalmicroSDcard slot capable of recognizing and using a 32 GB microSDHC memory card.[48]

Display

edit

The Samsung Galaxy S II uses a 108.5-millimetre (4.27 in)[11]WVGA (800 x 480)Super AMOLED Pluscapacitive touchscreenthat is covered byGorilla Glasswith anoleophobicfingerprint-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 regularRGBmatrix display which results in a 50% increase in sub-pixels. This translates to grain reduction and sharper images and text. In addition, Samsung has claimed that Super AMOLED Plus displays are 18% more power efficient than the older Super AMOLED displays.[49]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.[50]

Audio

edit

The Galaxy S II usesYamahaaudio hardware.[51]The Galaxy S II's predecessor, the original Galaxy S, usedWolfson's WM8994 DAC.[52]User feedback onInternet forumsas well as an in-depth review atClove,[51]have expressed the Yamaha chip's inferior sound quality compared to that of the Wolfson chip featured in the original Galaxy S.

Camera

edit

On the back of the device is an 8-megapixelBack-illuminated sensor[53]camera with single-LED flash that can record videos in full high-definition1080pat 30 frames per second.

It is the first mobile phone bySamsung Mobilethat is able to record videos in full high-definition (FullHD1080p).

There is also a fixed focus front-facing 2-megapixel camera forvideo calling,taking photos as well as general video recording, with a maximum resolution of 640x480 (VGA).

Near-field communication

edit

The Galaxy S II is one of the earliest Android devices to natively support NFCNear field communication.[34]This follows on from the GoogleNexus Swhich was the first de facto NFC smartphone device.[54]Reportedly the UK version was supplied without an NFC chip at the beginning of its production run,[55]with an NFC-equipped version released later in 2011.[56]

edit

Samsung has also included a new high-definition connection technology calledMobile High-definition Link(MHL). 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.[57]For the Galaxy S II, the industry standard micro USB port found on the bottom of the device can be used with an MHL connector for a TV out connection to an external display, such as ahigh definitiontelevision.[58]

USB on-the-go

edit

The micro USB port on this device also supportsUSB OTGstandard which means the Galaxy S II can act as a 'host' device in the same way as a desktop computer, allowing external USB devices to be plugged in and used.[10]These external USB devices typically includeUSB flash drivesand separately poweredexternal hard drives.A video demonstration on YouTube[59]has shown the OTG function to be readily available with an ordinary micro USB (B-type) OTG adaptor. The same YouTube video goes on to mention a successful test completed on a 2TBUSB external hard drive (requiring own power source) but however reports of failure when trying to connect USB keyboards, tested USB mice and tested USBgame pads.Currently the onlyfile-systemsupported for USB drives within OTG isFAT32.

Headphone plug

edit

A 3.5 mmTRRSheadset 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.

Connectivity

edit

CC3920, 67783, And 3392910. [60][61]Phones released to the US market lack the FM receiver. BCM4330 supportsWi-Fi Directthat enable devices to communicate directly with one another without having to interact with an access point. Although the BCM4330 chip supports Bluetooth 4.0, the Galaxy S2 is limited to Bluetooth 3.0 using the last Android version released by Samsung (4.1.2). Bluetooth 4.0 support has been introduced in Android 4.3 versions, however the upgrade to an alternative firmware is required.

Additional accessories available include:

  • Dock connectorfor battery charging andaudio-visualoutput[62]
  • MHL cable which makes use of the device'smicro USBport for HDMI output[62]
  • USB OTG adaptor for use with external USB devices such asUSB flash drives.[10]
  • Stylus penfor use on the device's capacitive screen.[62]Support for a stylus on the Galaxy S II was a precursor to theSamsung Galaxy Note.
  • A number of case manufacturers have released a variety of cases for the Galaxy S II.
  • A Samsung brandedBluetoothheadset for making phone calls.[63]
  • A pair of portable speakers powered by the phone's USB port.[63]
  • A vehicle mounting kit for dashboard placement of the phone, allowsGPSnavigation using the phone.[63]

Variants

edit

Galaxy S II – Model GT-I9100G

edit

The Samsung Galaxy S II GT-I9100G was released in late 2011, and is usually sold instead of the original GT-I9100 in certain markets (mostly Asia and some parts of Europe). An overview of the Samsung Galaxy S II GT-I9100G can be seen onSamsung's official website.[64]It features a Texas Instruments OMAP4430 SoC instead of the Exynos 4210 in the GT-I9100. It is visually identical to the GT-I9100, as well as having the same 1.2 GHz processor speed and dual-core ARM Cortex A9 processor technology. However, the SoC is of a different design and the Mali-400 GPU has been replaced by a PowerVR SGX 540 GPU. This difference in the SoC makes this variant incompatible with customROMsintended for the I9100, but it has been steadily gaining its own aftermarket support (such as fromCyanogenMod[65]) due to the relative ease of development and the openness of the TI OMAP platform.

T-Mobile – Model SGH-T989

edit

T-Mobile USAbegan taking pre-orders for its variant (Model SGH-T989) of the Galaxy S II on 11 October 2011 and began selling it in stores on 12 October 2011.[78]Prior to its release, T-Mobile's variant of the device was code named "Hercules" by Samsung.

The T-Mobile variant has important key differences from the "International" version of the Galaxy S II. The T-Mobile variant uses a 1.5 GHz dual-coreQualcommAPQ8060 (S3)Snapdragonprocessor, as opposed to the 1.2 GHz dual-core Exynos processor of the International version because the Exynos processor is not compatible with T-Mobile's 42 Mbit/s HSPA+ network. The cellular radio of the T-Mobile supports UMTS bands I (2100 MHz), II (1900 MHz), IV (1700 MHz) and V (850 MHz). The display of the T-Mobile variant, at 4.52 inches, is larger than that of the international version. The T-Mobile variant features four touch-capacitive buttons as opposed to the three-button hardware/capacitive combination found on the international version, this variant of the smartphone uses the powerful Adreno-220 series GPU and supports up to version 4.4.4–based ROMs of the Android OS[79]The T-Mobile variant, like the AT&T variant, supports Near Field Communications (NFC) integrated in the battery, which has 6.85Wh capacity.[70]

As of 8 March 2013, the T-Mobile variant can be updated to Android 4.1.2"Jelly Bean"using Samsung Kies.[80]

U.S. Cellular – Model SCH-R760

edit

U.S. Cellular's variant (Model SCH-R760) is equivalent to the Sprint variant, except for one specification; the U.S. Cellular variant does not include a 2500 MHz WiMax radio.

Galaxy S II Plus – Model GT-I9105/P

edit

The Galaxy S II Plus was announced inCES 2013.The phone has aBroadcomBCM28155SoCwith a 1.2 GHz dual-core processor and aVideoCoreIV HW GPU instead of the Mali 400MP in the original Galaxy S II. Both the original and the "Plus" have 1 GB of RAM, but the latter only has 8 GB of internal storage, half that of the original, of which the operating system takes a significant cut. It uses a hyperglazed plastic body (the same as the Samsung Galaxy S III) and is available in Chic White and Dark Blue. The phone originally ran on Android 4.1.2"Jelly Bean"with Samsung'sTouchWizNature UX.[81]An update to Android 4.2.2 was made available. Also released was a I9105P model, which supportsNFC.[82]
