Samsung announced the Galaxy S8 on 29 March 2017 at its Unpacked event and released it to the public starting 21 April 2017 in many countries. It launched alongside the Galaxy S8+ and became the eighth generation in the Galaxy S series. The phone was especially important for Samsung because it came after the Galaxy Note 7 battery issue and showed a fresh start for the company’s flagship lineup.
The Galaxy S8 introduced a new design with glass on the front and back and a metal frame. It measured about 148.9 × 68.1 × 8.0 mm and weighed around 155 grams, making it comfortable to hold. It was available in colors such as Midnight Black, Orchid Gray, Arctic Silver, Coral Blue and Maple Gold. The phone had an IP68 rating, meaning it was protected from dust and could handle water up to 1.5 meters for 30 minutes.
One of the main highlights was its 5.8-inch Super AMOLED Infinity Display. The screen had a resolution of 2960 × 1440 pixels and a taller 18.5:9 aspect ratio. This design reduced bezels and gave users more screen space without making the phone much bigger. The display supported Always-On Display and HDR content and was widely praised for its brightness and sharpness.
The Galaxy S8 came with two processor versions depending on the region. Global and Indian models used the Exynos 8895, while the US and China models used the Qualcomm Snapdragon 835. Both were built on a 10 nm process and were among the fastest processors in 2017. The phone included 4 GB of RAM and 64 GB of internal storage, with support for microSD cards up to 256 GB.
It launched with Android 7.0 Nougat and Samsung Experience UI and later received updates up to Android 9.0 Pie. Samsung also introduced Bixby, its voice assistant, along with a dedicated side button. However, early versions of Bixby had limited features, and some users did not find it very useful at launch.
The rear camera featured a 12 MP Dual Pixel sensor with an f/1.7 aperture and optical image stabilization. It supported 4K video recording and delivered strong low-light performance. The front camera was 8 MP with autofocus and also had an f/1.7 aperture. Camera performance was considered one of the best in its class at that time.
The phone had a 3000 mAh non-removable battery with Adaptive Fast Charging through USB-C. It also supported wireless charging with both Qi and PMA standards. Connectivity features included 4G LTE, Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.0, NFC for Samsung Pay and multiple GPS systems. It also kept the 3.5 mm headphone jack.
For security, Samsung added an iris scanner, face recognition and a rear-mounted fingerprint scanner. Some users criticized the fingerprint sensor placement because it was positioned next to the camera, making it slightly uncomfortable to reach.
Overall, the Galaxy S8 was praised for its modern look, tall display and strong performance. It played an important role in restoring trust in Samsung’s flagship devices and set the design direction for many smartphones that followed.
