The screens of the Galaxy S8 and bigger S8+ are larger despite the devices being about the same size as last year’s S7 and S7 Edge.
This time, both models feature displays that curve round the phones’ sides.
The launch follows Samsung’s botched release of the Note 7, which was recalled twice after fires.
The South Korean firm blamed the problem on battery faults and said it had since put in additional safety measures, including X-ray scans of batteries.
“The Galaxy S8 is arguably the most important launch of the last 10 years for Samsung and every aspect will be under the microscope following the Note 7 recall,” said DJ Koh, President of Mobile Communications Business, Samsung Electronics.
“The S8 is a unquestionably a strong product but Samsung must now deliver a faultless launch to move on from its earlier difficulties. If this happens it will emerge in an even stronger position.”
“The Galaxy S8 is our testament to regaining your trust by redefining what’s possible in safety and marks a new milestone in Samsung’s smartphone legacy.”
The new devices will be released on 21 April.
Consumers can purchase the smartphones in the Nigerian market from the 5th of May, 2017, through authorized dealers with the peace of mind offered by the 24-month warranty. Pre-registration begins April 10th and consumers who pre-order stand a chance to get a Starter Kit; a special pack filled with different S8 and S8+ accessories and a Clear View Standing Cover.
The S8 is priced at £690 and the S8+ at £780 – a jump on last year’s entry prices of £569 for the S7 and £639 for the S7 Edge.
Samsung was the bestselling handset manufacturer for 2016 as a whole, according to market research firm IDC.
Longer screens
The displays of the S8 and S8+, measuring 5.8in (14.7cm) and 6.2in (15.7cm) respectively, mean a more stretched aspect ratio than before, pushing the screens closer to the top and bottom of the handsets.
As a consequence, Samsung’s logo no longer features on the front, and the physical home button is replaced with an on-screen icon – in a similar manner to rival Android phones from Huawei and LG.
A pressure sensor and vibration module have, however, been built into the space behind the new virtual button to provide feedback.
Samsung suggests the displays’ 18.5:9 ratio makes them better suited to running two apps side by side. For example, there is now space to watch a video, use a chat app and still have room for a full touch-keyboard.
The screens are the same resolution as before but are now brighter, supporting high dynamic range (HDR) playback of videos for extra clarity.
The S8’s body is a little narrower than that of the S7, while the S8+’s is a bit wider than the S7 Edge but lighter – Samsung says both new devices can still be used one-handed.
Hello Bixby
The phones also introduce Bixby – a virtual assistant based on technology acquired from some of the original developers’ of Apple’s Siri.
The helper is activated by a dedicated side-button and allows 10 built-in apps – including a photo gallery, messages and weather – to be controlled by voice.
It is “context-aware”, meaning users can ask follow-up questions and assume it is aware of what is currently displayed.
Samsung said it expected owners to mix together voice commands and physical controls – for example asking to see all the photos taken today, then tapping the ones they want, before verbally requesting they be messaged to a friend.
The software can also be used to recognise objects seen via the phone’s camera. This can be used to identify a landmark, for example, or tell the owner how much a product would cost to buy online.
