In particular, the head of OPPO, Zhou Yibao, posted a concept image of a tri-fold device on the Weibo platform. This triggered the interest of technology enthusiasts. The image showed a device with sharp edges, a thin surround, and a possible under-display camera notch for selfies. Although Zhou later deleted the post, it suggested that OPPO might be exploring the tri-fold form factor.

OPPO’s developments in tri-fold technology are being matched by Huawei, TECNO, Xiaomi, and other manufacturers. These companies are also working on devices with three main folding parts. Huawei’s former CEO was even spotted using a tri-fold prototype. TECNO revealed its official concept on August 27th. Meanwhile, Xiaomi is working on a tri-fold phone, although details about this device are still limited.

Some believe that design and features are best showcased on a smartphone without needing a flashy display or theater. However, the concept image showed a hinge that seemed smooth and glossy, while the three panels at the back appeared to have a matte finish. It seems likely the phone will have a minimalist design, with thin top and bottom bezels and potentially an in-display selfie camera. Despite the image lacking a rear camera array or cover display, there were hints of a square shape with sharp corners.

As more manufacturers enter the tri-fold market, competition for innovation and market share is intensifying. TECNO’s device, for example, boasts a 10-inch 3K OLED screen when unfolded. Huawei’s tri-fold hardware reportedly offers a similar screen size. Xiaomi’s upcoming model is expected to feature the latest Snapdragon chip and a Leica camera system. As each company continues to innovate in design and functionality, the tri-fold market will see significant developments.

The tri-fold wars are heating up, suggesting that many new devices and gadgets may be launched in the coming months. OPPO, Huawei, TECNO, and Xiaomi are all competing for dominance, signaling a future where smartphones become increasingly foldable. Although specific release dates and pricing details are still unknown, one thing is clear: the tri-fold revolution is just beginning.
