The Guardian has published a considerable amount of information on Samsung's upcoming Galaxy S8 smartphone. The phone will reportedly launch in March with a headphone jack and a desktop dock, among other features. From the report: Samsung's Galaxy S8 will come in two sizes, have an almost bezel-less, edge-to-edge "infinity" display and an iris scanner, the Guardian has learned. The two variants will have screens in the 5in to 6in region, with the devices having the same or smaller proportions of previous versions of Samsung's flagship smartphone but with larger displays, according to several well placed sources talking to the Guardian. The S7 was available with either a 5.1in and 5.5in screen. The two smartphones are codenamed Dream and Dream 2, representing the smaller and larger Galaxy S8 respectively, according to two sources. Both versions will have screens that curve down at the left and right sides of the device similar to the Galaxy S7 Edge, two sources have said. The so-called "infinity display" will cover the majority of the front of the device, with very little body on the top and bottom of the screen not dedicated to the display. Two sources said there wasn't even room to put a logo or brand name on the front of the device. Samsung has moved the fingerprint scanner to the back of the device, multiple sources said. The Galaxy S8 will have a traditional 3.5mm headphone socket, according to several sources. Samsung also plans a range of new accessories for the Galaxy S8. Two sources said a new dock and service that turns the Galaxy S8 into an Android desktop computer, connecting to a monitor, keyboard and other peripherals called DeX (desktop extension) will be available. DeX has been likened to Microsoft's Continuum, which connects Windows smartphones to a desktop extension to allow them to be used as Windows PCs, but only with Windows Store applications.
