LG unreleased rollable smartphone pushes hardware limits despite company exit

LG arguably exited the mobile market because it prioritized radical experimentation over a steady "money maker." Before the lights went out, the company developed the LG Rollable, a device that serves as the spiritual successor to oddities like the swivel-screen LG Wing. Unlike the LG G8X and its modular dual-screen case, the rollable was a sophisticated, motorized attempt to solve the folding phone dilemma without the traditional hinge.

Engineering the expanding canvas

The device functions as a standard 6.7-inch slab that transforms into a 7.4-inch mini-tablet via a motorized expansion. The LG Rollable stores its extra screen real estate by wrapping it around the back of the chassis. LG even utilized clear glass on the rear, allowing the retracted portion of the display to function as a secondary notification ticker or a viewfinder for the 64-megapixel primary camera. This design forced the removal of physical side buttons, replaced by pressure-sensitive zones, while the power button and fingerprint sensor migrated to the rear.

Practical hurdles and durability gaps

Despite the "no crease" marketing potential, the display still exhibits slight wavering due to its rolling radius. Durability remains the primary concern; with exposed gears and a flexible screen constantly subject to environmental elements, the device lacks any meaningful water or dust resistance. Furthermore, the powerful motors—strong enough to push a five-pound MacBook Pro—present a genuine pinching hazard for smaller objects or thin fabric caught in the mechanism.

A legacy of overengineering

While the LG Rollable never reached retail shelves, the level of polish in its software—such as custom blooming-flower lock screen animations that scale with the display—suggests it was weeks away from launch. With 12GB of RAM and internal spring-loaded arms, it remains a testament to LG’s engineering prowess. As Samsung reportedly explores its own rollable form factor, the unreleased LG prototype stands as the high-water mark for what could have been a new era in mobile design.
