Before Samsung And Iphone Duo Phones Nokia Started Foldable Phone On Java

Legendary Nokia foldables: 1. The Nokia Communicator series (9300, 9500, E90) - the direct structural ancestors of the Galaxy Z Fold, opening like a book to reveal an ultra-wide landscape display. 2. The Nokia 6800/6820 'butterfly' phones - a numeric keypad that physically flipped over the front screen, rotating the OS 90 degrees into a split-QWERTY texting machine.

3. The Nokia N90/N93 'transformer' phones - multi-axis hinges letting users fold the screen like a laptop or twist it vertically into a handheld camcorder.

Powered by Java ME (the original app ecosystem), these devices offered true multitasking, responsive gaming and developer-aware UIs. Samsung perfected the flexible OLED and Apple the modern ecosystem, but Nokia invented the behavior of the foldable phone years earlier.
