Teardown of unreleased LG Rollable shows why rollable phones aren't a thing

LG's unreleased Rollable phone demonstrates why rollable smartphones never became mainstream despite impressive engineering. The device featured complex internal mechanisms including multiple motors, springy arms, and tracks to extend its screen, but this sophistication created major drawbacks including extremely high manufacturing costs and significant durability concerns from numerous failure points. While LG and other companies like Motorola and Oppo showcased rollable prototypes around 2020-2021, none ever launched commercially due to the combination of expense, fragility, and manufacturing complexity that made the technology impractical for mass production.
