If you haven’t already soaked up the leaks about it, the new LG V50 introduced today is a souped-up V40 with the new Snapdragon 855 processor, improved cooling, bigger battery, and the futuristic addition of 5G. The V50 is LG’s first 5G phone, in fact, and it’s also the first to be compatible with a new accessory the company is rolling out: an entire second screen.
The LG Dual Screen is essentially a folio case with a second OLED screen in it. The V50 has a 6.4-inch display, however the secondary panel here is limited to a 6.2-inch diagonal measurement, owing to its bigger bezels. I got to try out the Dual Screen system for myself here at Mobile World Congress, and there are both good and bad things to say about it.
Full screen
Starting with the positive, I’m confident that there’s demand for this kind of extra screen real estate. The more screen manufacturers can squeeze into a pocketable shape, the higher a price they’ll be able to charge. And, indeed, an LG V50 with an LG Dual Screen attached to it is pretty much as pocketable as the LG V50 itself. The added thickness won’t affect whether or not the already large device is a fit for your attire, Also cool is the hinge design on the case, which can rotate a full 360 degrees, allowing you to mirror your screen, which can be handy to show someone you’re photographing how you’re framing the shot.

Obviously, the next (and even cheaper) step is a clamshell phone with identical dual screens from the start.
Microsoft has a patent for a trick hinge that allows two screen to line up edge to edge to produce a single seamless display.
