But the South Korean company had previously hinted at the screen-engineering feat by showing off a line drawing of the feature in November.Image copyrightSamsungImage caption Samsung's Infinity-O screen design features a hole-punch selfie camera Neither handset features the kind of facial identification sensors that spurred Apple to introduce a notch in the first place.One industry-watcher said the phones instead represented mid-range devices, which made them a good match for the new look."Huawei is relentless at using the Honor brand to really grab as much share in the marketplace as possible," said Ben Wood, from the consultancy CCS Insight,"This is a very important part of the market, particularly for Samsung with the professional pressure it is facing from Huawei."Samsung was the world's most successful smartphone brand in the July-to-September quarter, when it shipped 72.2 million units, according to research company IDC.Huawei came second, according to the same report, with 52 million devices shipped over the same period.Image copyrightAsusImage caption The Asus ZenFone 5 features a typical notch design for its selfie camera But both companies face challenges.
Samsung has lost substantial market share in the mid- and lower-tiers to Chinese rivals over the past year, while Huawei faces claims it broke US sanctions on Iran and poses a wider security threat to the West.
Huge cameraHuawei also claimed the Honor View20's main camera, on its rear, represents another world-first.It offers a resolution of 48 megapixels and is the first to use of a sensor made by Sony that was announced in July.The benefit is that users can crop in more closely into their photos without risking them looking pixellated when printed out.
But the downside is that higher-resolution shots take up more storage space.Xiaomi has also indicated it will soon launch a handset with the same sensor.Samsung previously announced it had created its own 48MP sensor but has yet to reveal in which handset it will debut.
