Reviews summary

Based on 60 reviews

The Samsung Galaxy S III is the third iteration of Samsung’s highly successful Galaxy S and is currently the most popular smartphone available anywhere in terms of sales. After nearly 3 months on store shelves across the world, Samsung has already sold over 10 million units. And no doubt it's going to sell millions more, mainly because of the phone’s outstanding hardware and software features that make it a cut above the vast majority of the handsets offered by the competition.

The III’s highlights in terms of hardware include a 4.8-inch 720p HD Super AMOLED touchscreen display that’s covered with a layer of Corning Gorilla Glass 2, an 8-megapixel autofocus camera with LED flash and 1080p video recording capability, plus a 1.4 GHz quad-core Cortex A9 processor with 1GB of RAM. All of this, along with many other hardware niceties such as Wi-Fi, Bluetooth 4.0, and HSDPA data, makes it one of the most powerful and feature-rich Android smartphones ever.

Speaking of Android, the Samsung Galaxy S III comes with version 4.0 Ice Cream Sandwich pre-installed, and a free update to Android 4.1 Jelly Bean is already in the pipeline. This should make it one of the first handsets on the market to run the latest version of the Android software. It also has a bunch of noteworthy software features like S-Voice, which takes a user’s voice commands then executes the necessary actions, and Dropbox integration, which gives users 50GB of free online storage space for backup. For most people, though, the best feature of the Samsung Galaxy S III software-wise is its built-in support for the world’s most popular social networking sites and Google services.

There’s a 2100mAh battery located underneath the Samsung Galaxy S III’s back over, which is said to be good for up to 12 hours of 3G talk time. That’s an impressive feat considering the fact that the overall thickness of the handset checks in at just 9mm. Whether or not you are a fan of Samsung’s design or manufacturing philosophies, it’s hard to deny that they’ve made a darn good phone with the Galaxy S III.

Need To Know: Samsung Galaxy S III

1. Android 4.0 Ice Cream Sandwich is pre-installed as standard and a free upgrade to Android 4.1 Jelly Bean is on the way. (The Good)

2. The 4.8-inch 720x1280 pixel resolution Super AMOLED touchscreen display is among the best in its class and provides excellent picture quality. (The Good)

3. The lack of support for 4G LTE networks is something that users in certain areas will surely miss. (The Bad)

4. An otherwise expansive built-in display is considered by some users as entirely too big and makes the phone somewhat difficult to operate in that it requires both hands to use. (The Bad)

An amazing phone with creative software advancements

from TelecomTiger
With a large number of excellent features and functions, Samsung Galaxy S3 has set a benchmark for its close competitors - HTC One X and Apple. The only advantage HTC One X has over Galaxy S3 is its better screen resolution. The 1.5 dual core Qualcomm Snapdragon processor and 1 GB RAM has worked well with GS3. With its forceful promotion strategy, Samsung has an advantage over HTC One X and Apple. We consider it one of the best high end phones... Full review

Same great formula from the original, fast mobile data, slightly improved hardware

from Pocket-lint

For those of us outside the 4G coverage area, there's almost no point getting this phone at all, although it does have a good range of 4G frequencies, so you should see support for other UK networks when they launch 4G services.

When they're on top form, in central London or the other cities the 4G service is available, it's a brilliant thing to behold, but the price in terms of line rental and the drop in battery life seem too steep to be worth paying right now. This is a device for those who must have the newest, the best and the most expensive. Leave this phone to the Chelsea foo... Full review


Unquestionably one of the most well-rounded smartphones on the market

from Phonedog

There is no questioning the quality of the Galaxy S III. Top to bottom, it is a fantastic device. And while many would rather see Samsung begin to transition away from using an excess of plastic to something a little more classy and of higher quality, the S III holds it own, despite its frail-feeling frame. Still, they've greatly improved the Galaxy S III from last year's variants and have refined their flagship, in almost every way, to create a truly stellar handset.

The 4.8-inch HD Super AMOLED panel may not be the most dense of any smartphone display, but it is bright and full of... Full review

Full of features and definitely has the "wow" factor

from Sprint Users
This phone is definitely one I will keep for a while. I feel very comfortable using it and showing it off. It's just a sweet device. It looks great and behaves professionally. If you're in the market for an Android device, this is the one. It's worth the wait... Full review

Heavy on hardware, but even heavier on experience

from Android Guys

Hype confirmed. This handset is everything we’d expect out of Samsung’s flagship device on just about every front imaginable. Thanks to a unified branding and singular form factor, across multiple providers, there will be no mistaking one of these as better than the other. And, since it’s so widely available, the Galaxy S III stands as good a chance as any to knock the iPhone down another notch. With Samsung’s new smartphone you’ll come for the gorgeous and stay for the experience. Yes, some of the features can be found in third party apps or on other devices,... Full review


The screen is lovely and the phone is full of software features that'll make your head spin

from IntoMobile

The Samsung Galaxy S III is an impressive phone. The screen is lovely and the phone is full of software features that'll make your head spin. The camera is great and rivals that of the iPhone 4S. From a hardware-only perspective, it is the best Android phone Sprint has to offer at this time.

It surpasses the Galaxy Nexus with a significantly better camera, improved battery life and 4G LTE connectivity. Its closest rivals are the Motorola Photon Q 4G LTE and the HTC EVO 4G LTE. The Galaxy SIII has a bigger screen, larger battery and more RAM than the Photon Q. The EVO 4G LTE rivals t... Full review


Provides excellent value and is a device that will offer a lot of bang

from GottaBeMobile

There’s been a lot of talk about Sprint’s network. Pundits are quick to criticize the Now Network for not having a widely deployed 4G LTE network and supporters are fast to point out that Sprint remains the only carrier right now to offer unthrottled, unlimited mobile broadband data. If you’re a loyal Sprint customer considering an upgrade, the Sprint Galaxy S III provides excellent value and is a device that will offer a lot of bang. On the other hand, if you’re currently on a carrier with 4G LTE or 4G HSPA+ service in your area, the value proposition is a bit harde... Full review


A top of the line smartphone to power you through the day

from BitBitByte

If you are in the market for a new Android device, the S3 will not disappoint. Compared to the other big hitter in the Android world at the moment, the HTC One X, Samsung narrowly edges out HTC once again. The design isn’t up to my 2012 standards (the HTC One X is a sexy device) but what is packed inside is really worth the $200 price tag (with a new 2-year contract). Great battery life and a gorgeous screen really put this in the front of the line for a smart phone purchase. TouchWiz has always been an issue for me, and other users, but it isn’t as noticeable on the S3 as previ... Full review

Phone Scoop

A good phone that excels at nearly every feature

from Phone Scoop

Sprint's version of the Samsung Galaxy S III carries forward most of the strengths of its counterparts for other carriers. Samsung went for broke and packed the device with features that may lead to mass adoption of burgeoning technologies such as NFC.

Beyond the bells and whistles, the Galaxy S III is a good phone. It excels at nearly every feature. The hardware is excellent and the performance backs it up. The camera and video camera are good enough to record the birth of your child, (though you may want to watch that one in private thanks to the wide viewing angle of the bright d... Full review


Samsung Galaxy S III Review (Verizon)

from Pocketnow

If you don’t have a smartphone, or your contract is up, or you’re wondering what phone to get, we’ll make things simple for you: get this phone. You might be also considering the Galaxy Nexus, which is also a great phone, but the Galaxy S III is better in almost every way.

Even though we found some faults with the phone (both the case and the software), they’re our honest observations — but none of them should prevent you from buying this phone. The Galaxy S III isn’t just a stand-out product, it’s probably the best smartphone available righ... Full review

Poor/Weak radio antenna

We tried two of these phones and neither one worked in our area. Odd....our other Samsung phones (Droid Razor, i200 & Note III) work just fine.
