Igeekphone News: Xiaomi may have accidentally offered its first official glimpse of the long-rumored MIX Fold 5, with an unidentified large-screen foldable smartphone appearing prominently in promotional material for the latest HyperOS 4 Beta release.
The device was spotted in a promotional poster published by Xiaomi’s official HyperOS account on August 13. Although Xiaomi has not explicitly identified the smartphone as the MIX Fold 5, its design and positioning have fueled speculation that the company is preparing to introduce its next-generation large-screen foldable.
Mysterious Foldable Appears in HyperOS 4 Beta Material
On August 13, Xiaomi’s official HyperOS account published information highlighting new features included in the HyperOS 4 Beta.
A large-screen foldable smartphone appears prominently in the accompanying promotional artwork. The device features a distinctive large R-shaped design on the front, while its camera module appears to be positioned toward the upper-right area.
Xiaomi did not name the device in the promotional material. However, the appearance has attracted attention because the company is widely expected to be developing the MIX Fold 5, which would represent the next generation of its horizontally folding flagship smartphone lineup.
The promotional image could therefore provide an early indication of the design direction Xiaomi is taking with its upcoming foldable.
MIX Fold 5 Rumored to Feature a New Hinge Design
Previous reports have suggested that the Xiaomi MIX Fold 5 could receive several major hardware upgrades.
One of the most notable changes is reportedly a new self-developed seamless hinge. Hinge technology is particularly important for book-style foldables because it directly affects the device’s thickness, durability, folding experience and display crease.
The MIX Fold 5 is also rumored to use a horizontally oriented camera module, giving the rear of the phone a different appearance from the device shown in the HyperOS poster.
Other reported features include a side-mounted fingerprint sensor, suggesting that Xiaomi could continue to prioritize a thin and lightweight form factor while retaining a conventional capacitive fingerprint solution.
It remains unclear whether all of these rumored specifications will make it into the final production model.
Xiaomi’s Xuanji O3 Chip Could Power the Foldable
Performance is expected to be another major focus of the MIX Fold 5.
According to previous reports, Xiaomi could equip the phone with its self-developed Xuanji O3 chip. The platform is expected to compete with Qualcomm’s next-generation flagship mobile hardware, including the rumored Snapdragon 8E5 platform.

If the reports prove accurate, the MIX Fold 5 could become one of Xiaomi’s most powerful foldable smartphones, combining flagship-level processing with a large flexible display.
However, Xiaomi has yet to officially confirm the Xuanji O3’s specifications or its relationship with the MIX Fold 5.
A Successor to the MIX Fold 4
The potential MIX Fold 5 would succeed the Xiaomi MIX Fold 4, which was launched in July 2024.
The MIX Fold 4 started at 8,999 yuan in China and was positioned as Xiaomi’s premium large-screen foldable.
The previous-generation model featured a 7.98-inch internal display and a 6.56-inch external display, providing users with a tablet-like screen when unfolded while maintaining a conventional smartphone form factor when closed.

It was powered by Qualcomm’s third-generation Snapdragon 8 flagship platform and featured a Leica-branded quad-camera system using Summilux optics.
The MIX Fold 4 also included a 5,100mAh Xiaomi Jinjiang stereoscopic irregular-shaped battery, designed to maximize battery capacity within the phone’s slim foldable chassis.
Xiaomi Could Be Preparing a Major Foldable Upgrade
The foldable smartphone market has become increasingly competitive, with Samsung, Huawei, OPPO, vivo and other manufacturers continuing to develop thinner and more capable devices.
For Xiaomi, the MIX Fold series represents an important opportunity to compete in the premium foldable segment, particularly as manufacturers increasingly focus on reducing thickness while improving hinge durability, battery capacity and camera performance.
The reported combination of a new seamless hinge, flagship processing hardware and a redesigned camera system suggests that the MIX Fold 5 could represent a substantial evolution over its predecessor.
The possible appearance of the device in HyperOS 4 Beta promotional material also raises the possibility that Xiaomi is gradually preparing its software ecosystem for the new hardware.
What We Know So Far
At this stage, Xiaomi has not officially confirmed that the foldable shown in the HyperOS 4 Beta poster is the MIX Fold 5. The name, specifications, launch date and pricing remain unconfirmed.
Nevertheless, the appearance of a large-screen foldable in Xiaomi’s official software promotional material is notable. Combined with previous reports about the MIX Fold 5’s hinge, camera design and Xuanji O3 processor, it suggests that Xiaomi’s next-generation foldable may be moving closer to its official debut.
If Xiaomi maintains the premium positioning established by the MIX Fold 4, the MIX Fold 5 could emerge as a major competitor in the increasingly crowded global foldable smartphone market.
For now, the HyperOS 4 Beta poster provides one of the strongest visual clues yet that Xiaomi’s next large-screen foldable is taking shape, although more details will need to come directly from the company before its specifications and launch plans can be confirmed.
