The Unreleased Rollable Smartphone!

A rollable smartphone begins as a 6.7-inch slab and expands to a 7.4-inch mini-tablet through a three-finger swipe. The additional display is hidden along the edges and becomes visible through clear glass on the back, enabling software to show messages and camera interfaces for selfies using the primary cameras. Pressure-sensitive volume buttons sit on the left, while a power button on the back functions as a fingerprint reader. The lock screen uses blooming flower animations during expansion and contraction, and the Settings app slides in a column when opened. Strong motors drive the mechanism, and squeezing while open triggers automatic closing with an error message. Durability appears limited, with likely no water or dust resistance and the flexible display exposed to the environment when open.

"The rollable phone starts as a regular 6.7-inch slab phone. With a three-finger swipe, it expands to a 7.4-inch mini-tablet. The extra screen is hidden along the edges and visible through clear glass on the back, allowing software tricks like displaying messages or camera UI for selfies using the primary cameras."

"The phone has pressure-sensitive volume buttons on the left side and a power button on the back that doubles as a fingerprint reader. The back display can show various information and camera interfaces. The lock screen features a blooming flower animation when expanding and contracting."

"The Settings app slides over to add a column when opened and removes it when closed. These animations suggest LG was very close to release. The motors are surprisingly strong, capable of pushing a 16-inch MacBook Pro across a table."

"If you squeeze hard while open, the phone automatically closes to prevent damage and displays an error message. The device can pinch smaller items like microfiber cloths. The phone likely has no water or dust resistance, and when open, visible gear teeth and air gaps expose the mechanism to elements."
