LG Dual Screen review: A foldable enigma

I hold in my hands a smartphone accessory that sports a fully foldable screen. 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.
