Design The S III has a plastic
chassis measuring long, wide, and thick, with the device weighing . Samsung abandoned the rectangular design of the
Galaxy S and Galaxy S II, and instead incorporated round corners and curved edges, reminiscent of the
Galaxy Nexus. The device has been available in several color options: white (marketed as "marble white"), black, grey, brushed dark blue (marketed as "pebble blue"), red (marketed as "garnet red"), and brown. A "Garnet Red" model was made available exclusively to US carrier
AT&T on 15 July 2012. In addition to the touchscreen, the S III has several physical
user inputs, including a home button located below the screen, an
option key to the left side of the home button, a
back key on the right side of the home button, a volume key on the left edge and a power/lock key on the right. At the top there is a
headphone jack and one of the two microphones on the S III; the other is located below the home button. According to Samsung, the Exynos 4 Quad doubles the performance of the Exynos 4 Dual used on the S II, while using 20 percent less power. Samsung had also released several
4G LTE versions—4G facilitates higher-speed
mobile connection compared to
3G—in selected countries to exploit the corresponding communications infrastructures that exist in those markets. The South Korean and Australian versions are a hybrid of the international and 4G-capable versions.
Storage The S III has a maximum of 2 GB of
RAM, depending on the model. The phone comes with either 16, 32, or 64 GB storage; additionally,
microSDXC storage offers a further 64 GB for a potential total of 128 GB. Moreover, 50 GB of space is offered for two years on
Dropbox—a
cloud storage service—for purchasers of the device, doubling rival
HTC's 25 GB storage for the same duration. and displays the video's current file size (in
kilobytes) as well as remaining storage capacity (in
megabytes) in real-time during video recording. Samsung improved the camera's software over that of its predecessor to include zero
shutter lag, and a
Burst shot mode that allows capturing up to 20 full-resolution photos per row in quick succession. Another feature,
Best Shot, allows selecting the best photo out of eight frames captured in quick succession. The phone can also take pictures while recording videos. Photos can additionally be captured using voice commands such as "
cheese", "
shoot", "
photo", and "
picture". The shortcuts on the left pane are customizable. The rear-facing camera is complemented by a 1.9-megapixel front-facing camera that can record 720p videos. The Galaxy S3 records videos with
stereo audio and is able to capture 6 MP (3264×1836) photos during video recording, which is the full 16:9
aspect ratio section of the 4:3 image sensor.
Battery The S III's user-replaceable
Li-ion 2,100
mAh battery is said to have a 790-hour
standby time or 11 hours of talk time on 3G, compared to 900 hours in standby and 21 hours of talk time on 2G. The battery can be
wirelessly charged using a special charging pad (sold separately) that utilizes magnetic resonance to produce a
magnetic field through which electricity could be transferred. The S III is advertised as having an
MHL port that can be used both as a
micro-
USB On-The-Go port and for connecting the phone to
HDMI devices. However, a retailer later discovered that Samsung had modified the electronics of the port such that only the adapter made specifically for this model by Samsung could be used.
CNET TV torture-tested an S III by cooling it to , placing it in a heat-proof box and heating it to , and submerging it in water—the S III survived all three tests. The phone also did not exhibit any scratches when a key was repeatedly scraped against the display. However, Android Authority later carried out a drop test to compare the S III and the
iPhone 5. The screen on the S III shattered on the second drop test, while the iPhone received only minor scuffs and scratches on the metal composite frame after three drop tests.
Accessories Accessories for the Galaxy S3 include a
wireless charging kit, the
Pebble MP3 player, a docking station, a
C-Pen, a slimline case, and a car mount.
Software and services User interface The S III is powered by Android, a
Linux-based,
open source mobile operating system developed by Google and introduced commercially in 2008. Among other features, the software allows users to maintain customized home screens which can contain shortcuts to applications and
widgets for displaying information. Four shortcuts to frequently used applications can be stored on a dock at the bottom of the screen; the button in the center of the dock opens the application drawer, which displays a menu containing all of the apps installed on the device. A tray accessed by dragging from the top of the screen allows users to view notifications received from other apps, and contains
toggle switches for commonly used functions. Pre-loaded apps also provide access to
Google's various services. The keyboard software is equipped with a
clipboard manager. The S III uses Samsung's proprietary
TouchWiz graphical user interface (GUI). The "Nature" version used by the S III has a more "organic" feel than previous versions, and contains more interactive elements such as a water ripple effect on the precluded
lock screen, to
resemble its appearance in nature. To complement the TouchWiz interface, and as a response to Apple's
Siri, the phone introduces
S Voice, Samsung's
intelligent personal assistant. S Voice can recognize eight languages including English,
Korean,
Italian and
French. Based on
Vlingo, S Voice enables the user to verbally control 20 functions such as playing a song, setting the alarm, or activating driving mode; it relies on
Wolfram Alpha for online searches. With the
Wake-up commands feature, voice commands can be set to launch apps and tasks out of stand-by mode, such as S Voice, camera, music player, voice recorder, missed calls, messages, and schedule. The
Auto Haptic feature can complement audio with synchronous haptic feedback. The precluded telephone application is equipped with additional options for noise cancellation, call holding, volume boosting, and the ability to personalize the call sound.''''
Gallery software The new gallery software of the Galaxy S3 allows sorting photos and videos chronologically, by location, and by group. Photos with
tagged faces can also be sorted by person.
Video player The precluded video player software is newly equipped with the ability to play videos in a floating pop-up that can be moved freely around the screen. In addition, the video player application can show
motion thumbnails, which means that the preview thumbnails show a moving portion of the video.
Software updates The S III initially shipped with
Android version 4.0.4, named "
Ice Cream Sandwich", which became commercially available in March 2012 with the
Nexus S and
Galaxy Nexus. Ice Cream Sandwich has a refined user interface, and expanded camera capabilities, security features and connectivity. In mid-June 2012, Google unveiled
Android 4.1 "Jelly Bean", which employs
Google Now, a voice-assistant similar to S Voice, and incorporates other software changes. Samsung accommodated Jelly Bean in the S III by making last-minute hardware changes to the phone in some markets. Jelly Bean updates began rolling out to S IIIs in selected European countries, and to the
T-Mobile in the United States in November 2012. Samsung started pushing
Android 4.1.2 Jelly Bean to the international version of the S III in December 2012. This update shipped the so-called
Premium Suite Upgrade which brought additional features to the Galaxy S3, such as split-screen app view as known from the
Galaxy Note 2. In December 2013, Samsung began rolling out Android 4.3 for the S III, adding user interface features
backported from the
Galaxy S4, and support for the
Samsung Galaxy Gear smartwatch. In March 2014, Samsung started the rollout of
4.4.2 KitKat for the 2 GB variant of the S III. The Galaxy S III is Samsung's first phone not to get new preloaded
ringtones from software updates, a custom that is being continued to date.
Services The S III comes with a multitude of pre-installed
applications, including Google apps like
Google Play,
YouTube,
Google+,
Gmail,
Google Maps,
Voice Search and
Calendar, in addition to Samsung-specific apps such as
ChatON, Game Hub, Music Hub, Video Hub, Social Hub and Navigation. To address the fact that iPhone users are reluctant to switch to Android because the OS is not compatible with
iTunes, from June 2012 Samsung offered customers of its
Galaxy series the Easy Phone Sync app to enable the transfer of music, photos, videos,
podcasts, and text messages from an iPhone to a Galaxy device. The user can access Google Play, a
digital-distribution multimedia-content service exclusive to Android, to download applications, games, music, movies, books, magazines, and TV programs.
Interaction Apart from S Voice, Samsung has directed the bulk of the S III's marketing campaign towards the device's
"smart" features, which facilitate improved
human-device interactivity. These features include: "Direct Call", the handset's ability to recognize when a user wants to talk to somebody instead of messaging them, if they bring the phone to their head; "Social Tag", a function that identifies and tags people in a photo and shares photos with them, "Smart Alert", a haptic feedback (short vibration) when the device detects being picked up after new notifications have arrived; In addition, the S III can beam its screen to a monitor or be used as a remote controller (AllShare Cast and Play) and share photos with people who are tagged in them (Buddy Photo Share). The device also introduced Music Hub, an
online music store powered by
7digital with a catalogue of over 19 million songs. Its "Auto Haptic" feature vibrates synchronously to the audio output for intensification, similarly to the
audio-coupled haptic effect, a feature added to stock Android in 2021.
Voice over LTE The S III was the first smartphone to support
Voice Over LTE with the introduction of HD Voice service in South Korea. The phone enables
video calling with its 1.9 MP front-facing camera, and with support for the
aptX codec, improves
Bluetooth-headset connectivity.
Texting on the S III does not embody any new significant features from the S II. Speech-to-text is aided by Vlingo and Google's voice-recognition assistant. Not unlike other Android devices, there is a multitude of third-party typing applications available that could complement the S III's stock keyboard.
Enterprise On 18 June 2012, Samsung announced that the S III would have a version with
enterprise software under the company's Samsung Approved For Enterprise (SAFE) program, an initiative facilitating the use of its devices for "
bring your own device" scenarios in workplace environments. The enterprise S III version would support
AES-256 bit
encryption,
VPN and
Mobile Device Management functionality, and
Microsoft Exchange ActiveSync. It was scheduled to be released in the United States in July 2012. The enterprise version was expected to penetrate the business market dominated by
Research in Motion's
BlackBerry, following the release of similar enterprise versions of the
Galaxy Note, Galaxy S II and the
Galaxy Tab line of
tablet computers.
Developer edition A separate "Developer Edition" of the S III was made available from Samsung's Developer Portal. It came with an unlockable
bootloader to allow the user to modify the phone's software. == Variants ==
