The newly announced Samsung Galaxy Z TriFold features a triple rear camera setup. However, the company’s first tri-foldable may have initially been designed to include quad-rear cameras.
Images shared in a LinkedIn post by a Samsung executive suggest that a Galaxy Z TriFold prototype may have been tested with a quad-rear camera setup.

The executive is seen holding the Galaxy Z TriFold, but a closer look reveals what appears to be a four-camera setup on the back. The fourth cutout matches the others in diameter but is noticeably thinner.
The device shown is likely a prototype, suggesting Samsung initially considered a quad-rear camera setup before ultimately scrapping the plan.
Samsung’s Galaxy Z TriFold comes with a 200MP main rear sensor, a 12MP ultrawide camera, and a 10MP telephoto unit with 3x optical zoom support. The foldable goes on sale in South Korea on December 12, with availability in China, Taiwan, Singapore, the UAE, and the US to follow.
