LG Dual Screen review: A foldable
It’s got nothing to do with the beleaguered Samsung Galaxy Fold or Huawei Mate X, nor the half-dozen bendable phone prototypes from brands like Oppo, Xiaomi, Royale, and others. Rather, it’s LG’s Dual Screen, which retails alongside the Korean variant of the LG V50 ThinQ. The Dual Screen is a clamshell case which adds a display that acts more or less like an external monitor, conferring additional screen real estate without the irremovable bulk of a built-in solution. Aftermarket display cases are nothing new — the Nubia X shipped alongside one with a rear-facing OLED, for example — but the Dual Screen is somewhat novel in that the screen faces inward, much like the secondary display on the discontinued ZTE Axon M and Kyocera Echo.
App switching
The Dual Screen’s software experience is relatively bare-bones, but it worked without a hitch in my testing. When the case makes contact with the V50’s pins, you’ll see a persistent shortcut (which can be optionally hidden) that occupies the left portion of the screen. When you tap on it, you get a list of display options, including one that puts either the V50’s screen or secondary screen to sleep and another that swaps the panels’ content. You’ll find more granular controls within the Dual Screen settings screen, including a brightness slider for the secondary panel (by default, adjusting the V50’s screen brightness also adjusts that of the Dual Screen) and a wallpaper selector. It’s also here where you’re able to specify which app (if any) opens whenever the secondary screen switches on.
