Samsung’s Latest Software Might Have Leaked Its Own Trifold Phone Design

Samsung is rumored to be introducing its first trifold phone at Unpacked on July 9 alongside the Galaxy Z Fold 7, Z Flip 7, new cheaper foldables, and the Galaxy Watch 8 series. We may now know what the trifold design could look like, and it’s thanks to a leak from Samsung itself.

Hidden within the code of the latest One UI 8 update, teardown specialist AssembleDebug spotted the changes, as reported by Android Authority.

One UI 8’s NFC animations show a design for a trifold handset, and the design is different from devices such as the Huawei Mate XT. The design in One UI 8 appears to be similar to the concept device Samsung showed off under the name “Flex G” at MWC 2025. That’s the concept phone you can see pictured above.

If the animations are reflective of the final design, it will mean the device has two inward-folding hinges bringing together the two outer screens on top of the inner element. To imagine this device, think of the two extra displays unfolding like wings to make for a larger landscape display when unfurled.

These animations give us a rough idea of the design, but they don’t give an idea of the size or dimensions we can expect. If the device from MWC 2025 is anything to go by, expect a device like a medium sized tablet when unfolded.

The animations show a similar camera array to the Galaxy Z Fold series on the left hand rear of the phone. On the reverse, there’s a small punch-hole on the far right of the screen for selfie videos when the device is unfolded.

Samsung may be the first brand to sell a trifold phone in the United States. Huawei beat Samsung to market in other areas of the world, but Samsung seems to be the first brand ready to go on sale in the US and allow customers to buy a trifold device. The big question is whether there is enough demand for these sort of foldable phones.
