Samsung has launched the Galaxy Z TriFold, its first triple-folding smartphone that opens into a massive 10-inch display. Powered by the Snapdragon 8 Elite, it features a 200MP camera, a 5,600 mAh battery, and a slim 3.9mm profile when unfolded. Launching in South Korea on December 12, 2025, it currently faces limited competition, giving Samsung a chance to take foldables mainstream.
