Jan 16. 2019

High Screen-to-body Ratio Elevates Viewing Enjoyment

Triple Rear Camera Captures Stunning Images


Hong Kong – January 16, 2019 – Samsung Electronics H.K. Co. Ltd. today launched the Galaxy A8s, the first smartphone with Infinity-O Display, offering unprecedented boundless viewing experience to users. The Galaxy A8s comes with a 6.4-inch 19.5:9 high screen-to-body ratio, a mere thickness of 7.4mm, as well as a triple rear camera, and powerful and efficient performance, setting a new industry benchmark for mid-tier smartphones.


“As the leader who innovates the global smartphone industry, Samsung understands consumers are demanding more from technology nowadays. Backed by our outstanding research and development of innovative technologies for smartphones, we are very delighted to introduce another revolutionary product to the Galaxy A series – Galaxy A8s – and unleash brand new design possibilities for the industry. The groundbreaking ultra-high screen-to-body ratio offers a unique user experience,” said Yiyin Zhao, Managing Director of Hong Kong.


Momentous Infinity-O Display Design Offers Boundless Viewing Enjoyment

The Galaxy A8s is the first-ever Samsung smartphone to deploy Infinity-O Display technology, which offers users a more immersive and expansive viewing experience. The front camera is uniquely placed at the top left corner of the display, and the screen-to-body ratio is raised sharply to 19.5:9, further enhancing the boundless viewing enjoyment. In addition, for a more user-friendly Infinity-O Display, touchscreen function is added to the front camera. Users just need to swipe towards the right bottom corner to quickly launch the camera. A light serves as a reminder when users switch to front camera or use the selfie camera timer.


The Galaxy A8s comes with a 6.4-inch Full HD+ display and a thin body measuring at only 7.4mm, which is thinner than most mid-tier smartphones in the market. The sleek and ergonomic body offers a natural and comfortable grip as users explore the joys of life. The Galaxy A8s comes in Black, Blue and Gradation Black, while the main camera has different camera deco rings to match the body. The stylish design perfectly suits energetic users and the 3D back glass with gradient colors also flawlessly cater to the preference of young users. 


Powerful Triple Camera Captures the World You See

Samsung once again equips a mid-tier smartphone with the triple camera, helping users of the Galaxy A8s capture the real world anytime, anywhere. The 24MP main camera with F1.7 wide aperture allows users to take stunning photos, whether it’s in bright environments in the daytime, or lowlight environments at night. The telephoto camera with 10MP, F2.4 aperture and 2X optical zoom allows users to take crisp and clear shots even from a far distance. And the depth camera with 5MP, F2.2 and Live Focus functions enables users to take gorgeous portraits and accentuate the pictures’ subjects with real-time or post depth of field adjustment.


The Galaxy A8s is equipped with various camera functions powered by artificial intelligence, which help users take outstanding photos. The Scene Optimizer can automatically identify 20 kinds of scenes, including flower, person, food, sunset or sunrise, animals and more; also, it can optimize the saturation, white balance and brightness of photos. Flaw Detection can spot the four most common problems, such as eye blink, lens smudge, motion blur and back light, and notify the user to retake the picture, ensuring not a fantastic moment will be missed. Bixby Vision can identify six modes of surroundings, such as text, shopping, image, place and more, and provides the most useful of these information to users.


The front camera of 24MP, together with Smart Selfie Expression, enables users to take high-quality photos even in bright daylight [1] or lowlight environments – the camera will raise the brightness automatically and reduce the noise [2] to create bright and sharp selfies. The built-in Smart Beauty and Pro Lighting features, together with Selfie Focus, assist users to take excellent photos with ease. The Galaxy A8s also supports AR Emoji, AR stickers, stamps and filters to add more fun and creativity to photos.


From Work to Daily Life, Delivering Excellent Performance

The Galaxy A8s is equipped with Snapdragon 710 processor, with built-in 6GB RAM to ensure high efficiency and performance. The Galaxy A8s comes in a bezel-less design and a full screen. The App Pair feature helps users manage two apps simultaneously and conveniently. Samsung also offers the intelligent assistant Bixby [3] to assist daily lives of users and remind them of their daily schedule. At the same time, the built-in Dual Messenger enables the convenient use of two different accounts in the same messaging tool, perfectly separating messages from work and personal life. Samsung also provides Secure Folder to create a high level of security and encrypted space for storing files and apps, as well as facial and fingerprint authentication, ensuring the smartphone’s security and privacy.


The Galaxy A8s supports Samsung Pay [4]  and Smart Octopus, letting users enjoy a safe, simple and convenient mobile payment service, not to mention offers from over a thousand retailers throughout the year.
