Unveiled on 29 March 2017 during a media event in New York City, they succeed the Samsung Galaxy S7 and S7 Edge, with U.S. availability beginning on 21 April 2017, and UK availability scheduled for 28 April 2017.

The S8 contains upgraded hardware and major design changes over their predecessors, the Galaxy S7 and S7 Edge, including larger screens with a taller aspect ratio and curved sides on both the smaller and larger models, iris and face recognition, a new suite of virtual assistant features known as Bixby, and a docking station accessory that allows the phones to be used with a personal computer-styled desktop interface with keyboard and mouse input support.

The S8 received mostly positive reviews. Its design and form factor received praise, while critics also liked the updated software experience and the camera, despite the camera module itself not receiving an upgrade from the Galaxy S7. It received criticism for duplicate software apps, lackluster Bixby features at launch, and for the "misplaced" placement of the fingerprint sensor on the rear next to the camera and for poor biometric options for unlocking the phone. A video published shortly after the phone's unveiling proved that the device's facial recognition scanner could be fooled by showing it a photo of the user.

The S8 broke sales records for Samsung, with more than a million units booked in South Korea during the pre-order period, and overall sales numbers being 30% higher than the Galaxy S7.

Hardware :

The Galaxy S8 and S8+ both feature 1440p Super AMOLED displays, with an 18.5:9 aspect ratio taller than the 16:9 ratio used by the majority of smartphones; the S8 has a 5.8-inch panel, while the S8+ uses a larger 6.2-inch panel. The displays are both curved along the side bezels of the device, with minimal bezels that Samsung markets as an Infinity Display, and the display panel itself has rounded edges. The S8 features an octa-core Exynos system-on-chip and 4 GB of RAM; models in North American markets utilize the Qualcomm Snapdragon 835 instead. Both chips are manufactured by Samsung with a 10 nm process.^] They contain 64 GB of internal storage, expandable via microSD card. The Galaxy S8 is one of the first smartphones to support Bluetooth 5, supporting new capabilities such as connecting two wireless headphones to the device at once. It is also bundled with Harman AKG earbuds. Both smartphones have improved satellite navigation over the predecessors by including Galileo receivers.

Unlike past Galaxy S series models, the S8 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. The S8 features the same 12-megapixel "Dual Pixel" rear camera as the S7, with software improvements. The front-facing camera was upgraded to an 8-megapixel sensor with autofocus. The S8 features fingerprint and iris scanners; the fingerprint reader was located to the rear of the device, next to 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. Face recognition technology had previously been implemented in earlier models like the Galaxy S III and Galaxy S4.

The S8 and S8+ use non-removable 3000 and 3500 mAh batteries respectively; Samsung stated that it had engineered the batteries to retain their capacity for a longer period of time than previous models.  The S8 supports AirFuel Inductive (formerly PMA) and Qi wireless charging standards. Due to the recalls of the Samsung Galaxy Note 7, Samsung said in a press conference it is committed to stricter quality control and safety testing procedures on all of the company's future products.

Samsung also launched a Galaxy S8+ with 128 GB of storage and 6 GB of RAM exclusively in China and South Korea.

Software : 

The Galaxy S8 runs Android 7.0 "Nougat" 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 will support 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. 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 to 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 when Bixby officially rolls out. Bixby replaces S Voice, the voice recognition technology previously found in Samsung Galaxy models.
