TL;DR YouTuber Zack Nelson of JerryRigEverything obtained and fully disassembled LG’s unreleased Rollable phone.
The teardown shows LG’s impressively engineered device with a motorized expanding display that still feels ahead of 2026 smartphones.
The video highlights how close LG came to shipping a groundbreaking rollable handset before shutting down its mobile division.
In a rare, detailed look at a device the public was never meant to see, YouTuber Zack Nelson of JerryRigEverything has torn down LG’s unreleased rollable smartphone. The video reveals a near-finished product that still looks futuristic even though it was developed many years ago.

LG even built in software tricks, including animated wallpapers that grow with the screen and a rear second display mode where the flexible panel tucks under a glass back to show widgets and camera previews. According to LG’s own internal rating cited in the video, the mechanism was designed for around 200,000 extensions.
