Samsung has launched its first triple-fold smartphone, the Galaxy Z TriFold in the US this week, carrying a hefty price tag of US$2,899 (around A$4,400).

While there’s no word yet on Australian availability, the device is already being seen as a glimpse into the future of premium mobile hardware.

The Galaxy Z TriFold unfolds twice to reveal a massive 10-inch OLED display – the largest screen ever fitted to a Galaxy phone.

At its thinnest point, the device measures just 3.9mm, an impressive engineering feat considering the complexity of its dual-hinge, triple-panel design.

Powering the TriFold is Qualcomm’s Snapdragon 8 Elite chipset, paired with 16GB of RAM and 512GB of storage. There’s also a 5,600mAh battery with 45W fast charging and Samsung’s latest Galaxy AI features baked into Android 16 and One UI 8.

On the camera front, Samsung hasn’t held back. The TriFold features a 200MP main camera, alongside a 12MP ultra-wide and a 10MP telephoto with 3x optical zoom, plus two selfie cameras for use in folded and unfolded modes.

Samsung says durability has been a major focus, with a titanium hinge, reinforced display layers and testing rated for 200,000 folding cycles, which is roughly equivalent to opening and closing the device 100 times a day for five years.

The price positions the TriFold well beyond mainstream buyers, costing more than many premium laptops.

For now, it will be sold in a single black colour and one storage configuration in the US, with no pre-orders – sales will be first come, first served.

Whether triple-fold phones represent the next big shift or remain an ultra-premium niche, Samsung’s Galaxy Z TriFold has made it clear that the foldable era is far from over.
