Samsung will unveil its first commercial foldable phone at Samsung Unpacked on 20 February. It revealed as much in a teaser video for the event.

But, we don't yet know exactly how it will work. We have an idea, but what we've seen so far doesn't convey next-gen technology.

The foldable device shown on stage at the Samsung Developers Conference, widely reported to be called the Samsung Galaxy Flex when released, was simply a prototype and, we have to say, as ugly as sin.

A chunky brick, basically.

However, a patent unearthed by LetsGoDigital shows a similar technical design but a much thinner, better looking device. We're certainly hoping the Samsung Galaxy Flex is more like this than the concept model.

The patent was originally filed in 2017 with the US Patent and Trademark Office and recently approved.

Like the prototype with an Infinity Flex display, it shows a device with a large internal screen that folds in half and thereby switching from tablet to phone mode. On the rear are a front second display, plus a camera unit on the rear.

Where the patent is most interesting though is that the device depicted in the illustrations is much thinner than the one shown at SDC.

Much sexier, especially when recreated in render form as the team at LetsGoDigital supplied for our lead image at the top of this page.

You can also get a further idea of how it will look as it is very similar to the phone shown in Samsung's "The Future" advert showing on UK TVs now.

That video comes with the disclaimer that, "All scenarios are fictionalised and simulated. For illustrative purposes only." However, in terms of the Galaxy Flex and the patent images, it could look very close.

RootMetrics tested the four UK networks and EE was faster and more reliable than all of them, with better data performance. Their network has come a long way since they launched in 2012. Back then they had 11 UK cities covered by 4G. Today they cover most of the UK’s land mass, thanks to 19,000 state-of-the-art 4G sites. They’ve got faster, too – from 50Mbps to a maximum speed of 400Mbps. And they’re soon to experience even greater possibilities with the launch of 5G.
