Samsung's foldable display tech won't just be limited to book-like phones akin to the Galaxy Fold. The company used its annual Developer Conference to preview a vertically folding, clamshell-style form factor. The company only said it was "exploring" the concept as part of its overall work on foldable devices, but it clearly put some thought into the technology. A short demo showed a user recording video in full screen at one moment, and creating a split view with more extensive controls when folding the phone 90 degrees. This might be ideal for recording your hands-free TikTok clips -- you'd have a built-in stand.
