The Galaxy S8 and S8+ both feature 1440p OLED displays, with an 18.5:9 (37:18) aspect ratio taller than the 16:9 ratio used by the majority of smartphones released until then. The S8 has a 5.8-inch panel, while the S8+ uses a larger 6.2-inch panel. The displays on both devices curve along the side bezels of the device, with minimal bezels that Samsung markets as an "infinity display", and the display panel itself have rounded edges.{{cite web |first=Dieter |last=Bohn |title=This is the Samsung Galaxy S8, coming April 21st |url=https://www.theverge.com/2017/3/29/15087530/samsung-galaxy-s8-announced-features-release-date-video-specifications |website=The Verge |publisher=Vox Media |date=29 March 2017 |access-date=30 March 2017}} They use DCI-P3, offering what screen-testing website DisplayMate describes as the largest native color gamut, highest peak brightness, highest contrast rating in ambient light, highest screen resolution, lowest reflectance, and highest contrast ratio.{{cite web |first=Chris |last=Smith |title=Expert says Galaxy S8 has best phone display ever, and that's great news for the iPhone 8 |url=http://bgr.com/2017/04/04/galaxy-s8-vs-iphone-8-oled-display-review/ |website=BGR |publisher=Penske Media Corporation |date=4 April 2017 |access-date=13 May 2017}}{{cite web |first=Joel |last=Hruska |title=The Samsung Galaxy S8's display is the best you can buy: DisplayMate |url=https://www.extremetech.com/mobile/247058-new-displaymate-round-declares-galaxy-s8s-display-best-can-buy |website=ExtremeTech |publisher=Ziff Davis |date=4 April 2017 |access-date=13 May 2017}}

The S8 features an octa-core Exynos 8895 system-on-chip and 4 GB of RAM; models in North American and East Asian markets utilize the Qualcomm Snapdragon 835 instead. Both chips are manufactured by Samsung with a 10 nm process.{{cite web |first=Michael |last=Simon |title=Report: Snapdragon 835 will launch first in Galaxy S8, others have to wait |url=http://www.pcworld.com/article/3161139/android/report-snapdragon-835-will-launch-first-in-galaxy-s8-others-have-to-wait.html |website=PC World |publisher=International Data Group |date=24 January 2017 |access-date=30 March 2017 |archive-date=23 December 2018 |archive-url=https://web.archive.org/web/20181223105434/https://www.pcworld.com/article/3161139/android/report-snapdragon-835-will-launch-first-in-galaxy-s8-others-have-to-wait.html |url-status=dead }} They contain 64 GB of internal storage, expandable via microSD card.

Unlike past Galaxy S series models, the S8 line does not feature physical navigation keys, electing to use on-screen keys instead. However, unlike other implementations, the home button can still be activated if it is hidden or the screen is off. The S8's display features pressure sensitivity limited to the home button.{{cite web |first=Jacob |last=Kastrenakes |title=Samsung's Galaxy S8 has a pressure-sensitive home button built into the screen |url=https://www.theverge.com/2017/3/29/15105330/samsung-galaxy-s8-home-button-virtual-vs-hardware |website=The Verge |publisher=Vox Media |date=29 March 2017 |access-date=30 March 2017}} To prevent the home button from burn-in damage, its position moves slightly.{{cite web |first=James |last=Vincent |title=The Galaxy S8's home button moves, and there's a good reason for it |url=https://www.theverge.com/circuitbreaker/2017/4/28/15467302/samsung-galaxy-s8-home-button-moves-screen-burn-in |website=The Verge |publisher=Vox Media |date=28 April 2017 |access-date=28 April 2017}}{{cite web |first=Rob |last=LeFebvre |title=The Galaxy S8's home button shifts to prevent screen burn |url=https://www.engadget.com/2017/04/28/galaxy-s8-home-button-shifts/ |website=Engadget |publisher=AOL |date=28 April 2017 |access-date=28 April 2017}}

The Galaxy S8 Active features a rugged design and significantly tougher materials to make it shock, shatter, water, and dust resistant. It has a larger battery than either of the regular S8s, at 4000 mAh. Unlike the previous phones in the Active line, the S8 Active does not have tactile buttons, instead using onscreen keys like the regular variants of the S8. It also no longer has the dedicated action button of previous versions which could be reprogrammed to be a shortcut to favorite apps, with the action button being replaced with the Bixby button. The "infinity" edge display of the standard models is removed, and replaced with a metal frame and bumpers in the corners to protect from shocks, while the back is fitted with a "rugged, tough texture for a secure grip". Its screen also measures 5.8 inches, the size of the regular S8, and has quad HD Super AMOLED in 18.5:9 aspect ratio. The S8 Active is sold in Meteor Gray, but AT&T also has a Titanium Gold color.

While The Verge claims that the S8 uses the same 12-megapixel rear camera as the S7, though with software improvements, a report from PhoneArena claims that the phones carry new, custom camera modules.{{cite web |first=Daniel |last=P. |title=Galaxy S8 and S8+ come with new Sony IMX333 and Samsung camera sensors |url=https://www.phonearena.com/news/Galaxy-S8-and-S8-come-with-new-Sony-IMX333-and-Samsung-camera-sensors_id92623 |website=PhoneArena |date=March 31, 2017 |access-date=September 3, 2017}} In addition, the S8 has a Pro Mode, which functions similarly to a DSLR camera and has custom options for shutter speed, ISO, and colour balance. It also supports the raw imagery format Digital Negative. The front-facing camera was upgraded to an 8-megapixel sensor with autofocus.{{cite web |first=Sascha |last=Segan |title=Samsung Galaxy S8 |url=https://www.pcmag.com/review/352620/samsung-galaxy-s8 |website=PC Magazine |publisher=Ziff Davis |date=29 March 2017 |access-date=30 March 2017}} The S8 features fingerprint and iris scanners; the fingerprint reader is relocated to the rear of the device, to the left of the camera, due to the removal of the physical home button. In addition to an iris scanner, the S8 also features face-scanning as an option to unlock the phone.{{cite web |first=Ashley |last=Carman |title=The Galaxy S8's face-scanning feature might make you forget about its misplaced fingerprint scanner |url=https://www.theverge.com/2017/3/29/15098488/samsung-galaxy-s8-face-unlock-id-scanner-security |website=The Verge |publisher=Vox Media |date=29 March 2017 |access-date=5 April 2017}}{{cite web |first=Daniel |last=Bader |title=The Galaxy S8 has face recognition and iris scanning, and you have to choose one |url=http://www.androidcentral.com/galaxy-s8-face-recognition-iris-scanning |website=Android Central |date=3 April 2017 |access-date=5 April 2017}} Face recognition technology had previously been implemented in earlier models since the Galaxy S III.{{cite web |first=Dylan |last=Reynolds |title=Samsung unveils Galaxy S III smartphone with face, voice recognition |url=http://edition.cnn.com/2012/05/03/tech/mobile/samsung-galaxy-s-iii-smartphone/index.html |website=CNN |date=4 May 2012 |access-date=7 April 2017}}

The S8 and S8+ use non-removable 3000 and 3500 mAh Lithium-Ion batteries respectively, as compared to 3000 and 3600 mAh on the Samsung Galaxy S7 and S7 Edge respectively. Samsung stated that it had engineered the batteries to retain their capacity for a longer period than previous models.

The S8 supports AirFuel Inductive (formerly PMA){{cite web |first=Derek |last=Walter |title=Everything you need to know about wireless charging |url=http://www.techhive.com/article/3111369/smartphones/everything-you-need-to-know-about-wireless-charging.html |website=TechHive |publisher=International Data Group |date=2 September 2016 |access-date=30 March 2017}} and Qi wireless charging standards.

The S8 and S8+ were one of the very few phone models on the market that offered built-in support for a physical keyboard, thus competing for a market held almost exclusively by BlackBerry at the time. For these models, Samsung offered a specialty plastic case which featured a clip-on QWERTY keyboard that could be removed or added by the user at will. While not in use, the keyboard could be clipped to the back of the case. When in use, the OS detected the keyboard and adjusted the screen size and proportions accordingly, so that other software could be used normally. The keyboard model was EJ-CG950BBEGWW for the S8 and EJ-CG955BBEGWW for the S8+.{{cite web |title=Galaxy S8 Keyboard Cover, Black |url=https://www.samsung.com/us/mobile/mobile-accessories/phones/galaxy-s8-keyboard-cover--black-ej-cg950bbegww/ |access-date=19 September 2021 |website=Samsung.com |publisher=Samsung}}

The Galaxy S8 launched with the Android 7.0 "Nougat" operating system with the proprietary Samsung Experience (formerly TouchWiz) user interface and software suite. The software features a suite of assistant functions known as "Bixby", which is designed primarily to interact with Samsung's bundled applications and other supported services. The feature allows the use of voice commands to perform phone functions, can generate cards shown on a home screen page (replacing the Flipboard integration formerly featured) based on a user's interactions, and perform searches utilizing object recognition via the camera.

Bixby supports third-party integration via an SDK. The S8 supports the use of a docking station known as Samsung DeX to access a PC-like desktop environment on an external display, with support for mouse and keyboard input.{{cite web |first=Tom |last=Warren |title=Samsung's Galaxy S8 can turn into a PC with its DeX dock |url=https://www.theverge.com/2017/3/29/15104600/samsung-dex-galaxy-s8-dock-announced-price-release-date |website=The Verge |publisher=Vox Media |date=29 March 2017 |access-date=30 March 2017}} On 21 April 2017, coinciding with the phone's official retail date, reports surfaced that the default music player on the Galaxy S8 would be Google Play Music, continuing a trend that started with the S7 in 2016. However, for the S8, Samsung partnered with Google to incorporate additional exclusive features into the app, including the ability to upload up to 100,000 tracks to the service's cloud storage, an increase from the 50,000 tracks users are normally allowed to upload. Additionally, new users get a three-month free trial of the service, the same as given to users who purchase Google's own Pixel smartphone. Furthermore, Google stated that more Samsung-exclusive features will be added to the app in the future, and that the Bixby assistant will also be supported by the app.{{cite web |first=Chris |last=Welch |title=Samsung will use Google Play Music as the default music app on its devices |url=https://www.theverge.com/2017/4/21/15377004/google-play-music-samsung-galaxy-s8-exclusive-features |website=The Verge |publisher=Vox Media |date=21 April 2017 |access-date=21 April 2017}}{{cite web |first=Nathan |last=Ingraham |title=Galaxy S8 owners can upload 100,000 songs to Google Play Music |url=https://www.engadget.com/2017/04/21/samsung-galaxy-s8-google-play-music-partnership/ |website=Engadget |publisher=AOL |date=21 April 2017 |access-date=21 April 2017}} Bixby replaces S Voice, the voice recognition technology previously found in Samsung Galaxy models.{{cite web |first=Brian |last=Reigh |title=We need to talk about Samsung's Bixby |url=http://www.androidauthority.com/samsung-bixby-problems-760859 |website=Android Authority |date=April 2017 |access-date=27 April 2017}}

Dan Seifert of The Verge praised the design of the Galaxy S8, describing it as a "stunning device to look at and hold" that was "refined and polished to a literal shine", and adding that it "truly doesn't look like any other phone you might have used before". The hardware of the device was described as "practically flawless". Seifert also liked the new software, writing that "Samsung is known less for polish and more for clumsiness. In a refreshing change of pace, the software on the S8 is, dare I say, {{sic|good}}". However, he criticized the Bixby assistant, writing that "in its current state, it doesn’t do much at all", and also criticized the number of duplicate apps. Regarding performance, he wrote that the S8 was "fast and responsive, but so is virtually every other premium phone you can buy, and the S8 isn’t noticeably faster or quicker than a Google Pixel, LG G6, or iPhone 7".{{cite web |first=Dan |last=Seifert |title=Samsung Galaxy S8 review: Ahead of the curve |url=https://www.theverge.com/2017/4/18/15328968/samsung-galaxy-s8-review-s8-plus |website=The Verge |publisher=Vox Media |date=18 April 2017 |access-date=21 April 2017}} Fellow Verge reporter Vlad Savov felt that the placement of the fingerprint sensor was "a perplexing decision if we consider it as a deliberate design choice", but noted reports from Korea claiming that Samsung had originally intended for the fingerprint reader to be built directly into the screen, but was unable to reach a desirable implementation in time for release.{{cite web |first=Vlad |last=Savov |title=The Galaxy S8's misplaced fingerprint scanner was probably a last-minute change |url=https://www.theverge.com/2017/4/1/15147998/samsung-galaxy-s8-fingerprint-reader-location |website=The Verge |publisher=Vox Media |date=1 April 2017 |access-date=21 April 2017}} The Verge wrote that "Samsung’s six-month-old S8 has cutting edge features and design with fewer issues than other Android phones" like the Google Pixel 2 and LG V30, and that the "OLED screen stretches to the edges of the device and curves on its sides in an almost liquid fashion. It makes the S8 look just as fresh today as it did when it debuted", and pointing out that the S8's popularity and carrier support guaranteed plenty of third-party accessories.{{Cite web|url=https://www.theverge.com/2017/7/24/15914934/best-smartphone-apple-ios-google-android|title=The best phone you can buy right now|first=Dan|last=Seifert|date=24 July 2017|website=The Verge}}

Chris Velazco of Engadget similarly praised the design, stating that "from their rounded edges to their precisely formed metal-and-glass bodies, they feel like smaller, sleeker versions of the Galaxy Note 7", and also praised the display as being simply "awesome". Velazco also praised the software, calling Samsung's added interface "subtle and thoughtful in its design choices". While noting that the Bixby assistant wasn't ready yet, he did compliment the promised voice features as being more granular than those offered through Siri or Google Assistant, and wrote that "With that kind of complexity involved, maybe it's no surprise this stuff isn't done yet". Also praising performance and the camera, though noting that "The 12-megapixel sensors on the back haven't changed much since last year. That's not a bad thing since they were great cameras to start with", Velazco summarized his review by writing that the devices "aren't perfect, but they're as close as Samsung has ever gotten".{{cite web |first=Chris |last=Velazco |title=Samsung Galaxy S8 and S8 Plus review: Redemption is here |url=https://www.engadget.com/2017/04/18/samsung-galaxy-s8-and-s8-plus-review/ |website=Engadget |publisher=AOL |date=18 April 2017 |access-date=21 April 2017}} Brandon Russell of TechnoBuffalo claimed that the camera could not beat Google's Pixel smartphone.{{cite web |first=Brandon |last=Russell |title=The Galaxy S8's camera couldn't beat the Google Pixel |url=https://www.technobuffalo.com/2017/05/15/galaxy-s8-google-pixel-camera/ |website=TechnoBuffalo |date=15 May 2017 |access-date=17 May 2017}}

Ron Amadeo of Ars Technica noted that the device's unusual aspect ratio resulted in pillarboxing when watching 16:9 video without zooming or stretching it. He complimented the feel of the S8, calling it "perfected", but criticized the glass back for being "more fragile" and that "Glossy, slippery glass doesn't feel as good in your hand as metal does, either. For the top-tier premium price tag, we'd prefer Samsung to put in the extra work and use a metal back". He criticized the biometric options for unlocking the phones, writing that "There's an iris scanner, a fingerprint reader, and face unlock. The problem is none of them are any good", and also criticized duplicate apps, writing that "most of which can't be removed and aren't very compelling". Additionally, he criticized Bixby, calling it "an odd addition" due to the phone's Google Assistant functionality already present.{{cite web |first=Ron |last=Amadeo |title=Galaxy S8 review: Gorgeous new hardware, same Samsung gimmicks |url=https://arstechnica.com/gadgets/2017/04/samsung-galaxy-s8-review-shiny-new-hardware-meets-old-software-habits/ |website=Ars Technica |publisher=Condé Nast |date=21 April 2017 |access-date=21 April 2017}}

Prior to the official release, it was reported that some Galaxy S8 displays had a bad white balance, causing them to exhibit a reddish tint.{{cite web |first=Ron |last=Amadeo |title=Samsung Galaxy S8 to get software patch for "red tint" issue |url=https://arstechnica.com/gadgets/2017/04/samsung-galaxy-s8-to-get-software-patch-for-red-tint-issue/ |website=Ars Technica |publisher=Condé Nast |date=24 April 2017 |access-date=9 May 2017}} Samsung stated that the Galaxy S8 was "built with an adaptive display that optimizes the color range, saturation, and sharpness depending on the environment", but noted that the device's operating system provides settings for manually adjusting the display's appearance and white balance.{{cite web |first=Cho |last=Mu-Hyun |title=Samsung confirms Galaxy S8 red display issue |url=https://www.zdnet.com/article/samsung-confirms-galaxy-s8-red-display-issue/ |website=ZDNet |publisher=CBS Interactive |date=18 April 2017 |access-date=22 April 2017}}{{cite web |first=Mariella |last=Moon |title=Early Galaxy S8 owners complain of red-tinted screens |url=https://www.engadget.com/2017/04/19/galaxy-s8-red-tinted-screens/ |website=Engadget |publisher=AOL |date=19 April 2017 |access-date=22 April 2017}} On 21 April, Samsung stated that the red tinting was purely a software issue, and would be patched in a future update.{{cite web |first=Shin |last=Ji-hye |title=Samsung to update Galaxy S8 software for red screen |url=http://www.koreaherald.com/view.php?ud=20170421000257 |website=The Korea Herald |date=21 April 2017 |access-date=22 April 2017}} The Investor reported that Samsung would replace the affected devices if a software update did not fix the issue.{{cite web |first=Kim |last=Young-won |title=Samsung plans software update for Galaxy S8 to address reddish screens |url=http://www.theinvestor.co.kr/view.php?ud=20170421000529 |website=The Investor |date=21 April 2017 |access-date=22 April 2017}} Updates in various regions started rolling out in early May, fixing the issue.{{cite web |first=Harish |last=Jonnalagadda |title=Galaxy S8 and S8+ update to fix red tint issue is now rolling out in India and Europe |url=http://www.androidcentral.com/galaxy-s8-and-s8-update-fix-red-tint-issue-now-rolling-out-india |website=Android Central |publisher=Mobile Nations |date=1 May 2017 |access-date=9 May 2017}}{{cite web |first=Daniel |last=Bader |title=Telus and Bell rolling out Galaxy S8 and S8+ 'red tint' fix |url=http://www.androidcentral.com/telus-rolling-out-galaxy-s8-and-s8-red-tint-fix |website=Android Central |publisher=Mobile Nations |date=8 May 2017 |access-date=9 May 2017}}{{cite web |first=Chris |last=Mills |title=The fix for the Galaxy S8's screen problem has finally reached the US |url=http://bgr.com/2017/05/02/galaxy-s8-red-tint-update-us-available/ |website=BGR |publisher=Penske Media Corporation |date=2 May 2017 |access-date=9 May 2017}}

Reports surfaced at the end of April 2017 that some Galaxy S8 devices were "restarting by themselves".

Shortly after the phone's unveiling, bloggers produced a video showing that the Galaxy S8's facial recognition scanner could be tricked to unlock the phone by showing it a photo of the user.{{cite web |first=Ashley |last=Carman |title=The Galaxy S8's facial scanner can, unsurprisingly, be tricked with a photo |url=https://www.theverge.com/2017/3/31/15136226/samsung-galaxy-s8-face-scan-security |website=The Verge |publisher=Vox Media |date=31 March 2017 |access-date=5 April 2017}}{{cite web |first=Ron |last=Amadeo |title=Galaxy S8 face recognition already defeated with a simple picture |url=https://arstechnica.com/gadgets/2017/03/video-shows-galaxy-s8-face-recognition-can-be-defeated-with-a-picture/ |website=Ars Technica |publisher=Condé Nast |date=31 March 2017 |access-date=5 April 2017}} In a statement to Business Insider, a Samsung spokesperson stated that "Facial recognition is a convenient action to open your phone – similar to the 'swipe to unlock' action. We offer the highest level of biometric authentication – fingerprint and iris – to lock your phone and authenticate access to Samsung Pay or Secure Folder".{{cite web |first=Amit |last=Chowdhry |title=Samsung Acknowledges Galaxy S8 Facial Recognition Security Limitations |url=https://www.forbes.com/sites/amitchowdhry/2017/03/31/samsung-acknowledges-galaxy-s8-facial-recognition-security-limitations/ |website=Forbes |date=31 March 2017 |access-date=5 April 2017}}

There is a high possibility that this issue does not exist at all and that the video in question is faked.{{citation needed|date=December 2020}}

In May 2017, researchers from the Chaos Computer Club posted a video showing that the S8's iris recognition system can be fooled with a contact lens and a suitable photograph of an eye.{{cite web |first=Chris |last=Ip |title=The Galaxy S8 iris scanner can be hacked with aging tech |url=https://www.engadget.com/2017/05/23/galaxy-s8-iris-scanner-hacked/ |website=Engadget |publisher=AOL |date=23 May 2017 |access-date=24 May 2017}} Samsung told BBC News that it was "aware of the issue", and stated that "If there is a potential vulnerability or the advent of a new method that challenges our efforts to ensure security at any time, we will respond as quickly as possible to resolve the issue".{{cite web |title=Samsung S8 'eye security' fooled by photo |url=https://www.bbc.com/news/technology-40012990 |website=BBC News |publisher=BBC |date=23 May 2017 |access-date=24 May 2017}}
