Samsung Galaxy Tab S3 review

The world’s first tablet running HDR video you can’t watch – yet

Our Verdict

The Samsung Galaxy Tab S3 is the best Android tablet to date, headlined by an HDR-ready screen, four powerful speakers and an upgraded S Pen that’s included in the box, although you’re going to have to pay for the keyboard. Just don’t expect to see much HDR video content right away, or have Android meet all of your 2-in-1 tablet needs next to a similarly priced laptop.


  • Samsung’s best tablet design yet
  • Includes the S-Pen stylus for free
  • HDR-ready future-proofed screen


  • Keyboard is a costly extra
  • Just as expensive as iPad Pro
  • Tablet multitasking can't replace a laptop

The Samsung Galaxy Tab S3 remains the best Android tablet you can buy, today and its iPad Pro-level price is actually slightly cheaper headed into the holidays.

That's good news because this is our favorite Samsung tablet design so far and it can do almost everything an iPad can do for a better price on sale.

In fact, watching the dystopian alternate-history Amazon TV series The Man in the High Castle on the Samsung Galaxy Tab S3’s HDR screen prompts an analogy: what if Apple’s iPad Pro ran Android?

That’s pretty much what we have here. It’s Android’s first worthy competitor to the iPad Pro 9.7, with top-of-the-line specs to match, and it pairs well with the elegant-looking Samsung Galaxy S8 and Galaxy Note 8 – also feature-packed and enveloped in glass.

The Galaxy Tab S3 is easily the best Android tablet you can buy right now thanks to its all-glass design upgrade, future-proofed HDR-ready display and included S Pen. It's hardly a difficult call for us to make – the year-old Google Pixel C is its only real challenger at a similar size, and the Tab S3 replaces the now-cheaper Samsung Galaxy Tab S2.

What is a challenge is determining who the Tab S3 is right for. It costs $599 (£599, AU$780), and while it comes with the S Pen (Apple’s tablet does not offer a stylus in the box), the keyboard is separate. When you add it all up, it borders on cheap laptop prices, and there’s no cheaper 8-inch Tab S3 to give you an affordable entry-level option.

You are getting the first HDR-ready tablet with better brightness and contrast ratio with the Samsung Galaxy S3 Tab, but we're still waiting for Netflix and Amazon Video to flip the switch on showing HDR content on this Android tablet. So far, only the LG G6 runs Android and supports HDR video through Netflix.

The Galaxy Tab S3 is Samsung’s best travel-friendly 2-in-1 tablet that can pull off productivity – if you’re willing to pay for the separate keyboard. It’s thinner and lighter than the equally tempting 2-in-1 Samsung Chromebook Pro laptop, which doesn’t have a detachable keyboard and includes a smaller S Pen, and it finally gives the iPad Pro some meaningful competition.

Samsung Galaxy Tab S3 price and release date

  • You can now get it for a cheaper price in the US
  • Tablet with the S Pen costs $599 (£599, about AU$780)
  • The keyboard is separate at $129 (£119)
  • Released on March 24, 2017 in the US, March 31, 2017 in the UK

As mentioned, the Samsung Galaxy Tab S3 costs $599 (£599, about AU$780), meaning it’s around the same price as an iPad Pro 9.7 at $599 (£549, AU$849). Besides the Wi-Fi-only model, there will also be a Wi-Fi+cellular option, which we anticipate will be slightly more expensive.

The real value over Apple’s tablet comes from the S Pen, which is included with the Tab S3 – the Apple Pencil costs an extra $99 (£99, AU$145). You also don’t need to worry about recharging Samsung’s S Pen, and you’re getting more levels of pressure for drawing and handwriting.

The Galaxy Tab S3 keyboard is a separate purchase, with Samsung charging $129 (£119). In the UK, the company has tempting pre-order deal that includes the keyboard for free; in the US, we’ve found the tablet is only bundled with a 64 microSD memory card, which is a rather less generous offer.

As for the Samsung Galaxy Tab S3 release date, it became available in US stores on March 24, while the UK wasn't too far behind with a March 31 launch date. Both regions opened Tab S3 pre-orders on March 17.


  • Elegantly designed glass and metal tablet design
  • More comfortable to hold than its plastic predecessor
  • Otherwise looks exactly like the Galaxy Tab S2

The Samsung Galaxy Tab S3 touts a small but likable design upgrade over the Galaxy Tab S2, even if it’s easy to mistake it for Samsung’s year-and-a-half-old tablet from the front.

The best changes happen round back, where the Tab S3 sports a new glass back panel in either black or silver. It looks and feels better than the rubberized plastic cover of the Tab S2, and the glass is more comfortable to hold; while you’re trading instantly collected sweat marks on the older model for fingerprints and smudges on the Gorilla Glass back, you’re ending up ahead.

Samsung can technically still claim that the Tab S3 is thinner and lighter than an iPad Pro, with dimensions of 237.3 x 169 x 6mm and a weight of 429g (the iPad Pro is 6.1mm thick and weighs 437g). But don’t be fooled; the variations are hardly noticeable. The Tab S2 is 5.6mm and 389g, and we felt barely any difference between the three slates. 

The Tab S3 looks and feels like a blown-up Samsung Galaxy S7 phone, with a useful physical fingerprint sensor home button, and 'back' and 'recent' capacitive buttons aligned at the bottom. Without the keyboard attachment, it excels at being an entertainment device first and foremost.

The real difference is seen and heard in the HDR display, which pumps up the contrast ratio, and the four speakers, which pump out the volume better than a tablet with a mono speaker. We got a taste of HDR on a mobile device with the short-lived Samsung Galaxy Note 7 and it's coming back to a Samsung phone with the Galaxy S8 and Galaxy S8 Plus. In between, it’s debuted on a tablet, bringing the promise of more true-to-life video content in the future.

HDR display and quad speakers

  • Brilliant HDR-ready screen awaits HDR video content
  • Future-proofed as the world's first HDR-ready tablet
  • Its four speakers can get loud and are finely tune

Samsung tablets and phones already have the best screens going, with bright and pixel-dense Super AMOLED display panels. Now, by including HDR technology, Samsung is making them even better.

High Dynamic Range (HDR) gives the same 2048 x 1536 Quad HD resolution higher contrast ratios and brighter highlights. This is especially important in darker movie scenes in which you tend to lose too much of the picture to shadow.

The Tab S3’s support of the new HDR10 standard is actually a bigger deal than if Samsung packed a 4K screen into a 9.7-inch tablet. The expanded brightness range does more than extra pixels would at this small size – more pixels matter when you’re dealing with a larger 4K television.

Here’s the problem: there’s not a lot of HDR video content available today. It’s being rolled out with streaming video services like Amazon Video and Netflix already on board on Samsung, LG and Sony TVs, but we weren’t able to find HDR video on these services at the tablet's launch. 

Instead, we had to rely on Samsung HDR demos and movie trailers to enjoy what’s ultimately the future of video. It’s definitely a jump up in quality, but as the content isn't here yet, you’re paying in advance for a tablet that will deliver that improved quality soon, but not right now. That makes the Tab S3 an amazing technical feat, but a hard sell to average consumers at launch.

What you can take advantage of right now are the quad speakers on the Tab S3. They reach a more powerful volume than what we've heard from the mono Tab S2 and so many other tablets. Better yet, they’re calibrated to your movements, so as you rotate the tablet the stereo speaker orientation changes, so you’re never holding it the wrong way for sound. 

As long as you’re not expecting deep base, these AKG-tuned quad HD speakers go ear-to-ear with the those on the equally-rich-sounding iPad Pro 9.7. You can get some bass out of the Tab S3 with the right headphones, which you’re probably going to use more often when roaming with this tablet in public.

And good news: this tablet has both a 3.5mm headphone jack on the bottom of the frame, and supports Bluetooth 4.2. No one is getting rid of headphone jacks in tablets – yet.

S Pen

  • Larger than the S Pen in Note phones, tablets and Chromebooks
  • Stylus design is flat and has a clip – it won't roll away on you
  • But there's nowhere to holster it without buying the keyboard

The Samsung Galaxy Tab S3 transforms in look and potential with the included S Pen and keyboard attachment. They’re the must-have accessories to unlock the full potential of this 2-in-1 tablet.

The S Pen is an upgrade from the thin stylus we’ve been using on Note phones and the Samsung Chromebook Pro. At 9.4mm thick it’s bigger and easier to hold, and makes the previous S Pen look like a toothpick by comparison. It still has a fine 0.7mm tip (this time made of rubber instead of plastic), and a clickable side button for bringing up the familiar Air Command tools.

All the usual S Pen tools are here, including Notes, Smart Select (create cropped or lassoed screenshots and GIFs), and Screen Write (write directly on a screenshot). There are also three newer functions that can be added to the fanned-out shortcut list: Translate, Magnify (zoom in) and Glance (dock and quickly view an app).

Handwriting and drawing are naturally better on a tablet using a thicker S Pen, too. It’s around the same width as the Apple Pencil, but shorter and boasts four times as many pressure levels. It really captures every angle, which can be great for shading, depending on the app you’re using. Samsung includes two apps – Notes and the coloring-book-like PEN.UP – and there are more in the Google Play Store.

The S Pen doesn’t slot inside the thin tablet, so you can’t seamlessly hide the thicker stylus when it’s not in use. Instead, Samsung has added an pen holder loop for the keyboard – if you buy the keyboard. The good news is that the S Pen doesn’t need to be charged, and doesn’t roll away constantly, as it has two flatter sides and a clip. The Apple Pencil likes to roll off tables because there’s nowhere to put it and, if frequently used, is always at risk of being out of juice.

Keyboard attachment

  • Doubles as a case that wraps around both sides
  • Doesn't require charging or pairing – it just works
  • End flap can't shut off the screen or close magnetically

The Samsung Galaxy Tab S3's keyboard attachment is worth the extra money if you’re looking to substitute this tablet for a laptop. Its cramped layout (a necessity) is still useable, with decent travel when you hit the plastic keys – and all the important keys are here.

What’s missing? There are no function keys along the top (we’re okay with that), and it’s sorely missing a home button, requiring you to reach for the fingerprint home sensor on the tablet and possibly knocking your coffee over in the process. We’d also like to see the search key bring up Google Search instead of Google Now On Tap, requiring an extra screen press for the search bar.

A good amount of travel on these plastic keys

Everything folds up nicely, enveloping the tablet in a soft plastic cover on both sides. That’s a big plus. Apple’s iPad Pro keyboard cover only protects the front screen – and aluminum does dent, much like glass shatters. Samsung basically throws in a back cover for free.

Best of all, there’s no need for Bluetooth pairing or charging. The keyboard has six Pogo pins above the top row of keys, and these magnetically clip to the Tab S3’s side frame. Samsung has its own version of the Smart Connector.

We just wish its magnets were stronger. Picking the tablet up by the screen often detaches the bottom part of the keyboard (luckily the back, where there are more magnets, stays secured). The end of the screen cover should also be magnetic, and should turn off the screen when closed. It doesn’t – instead, it can flap open if you’re not careful.
