Camera watermark leaks are offering an early look at Xiaomi’s upcoming Xiaomi 17 Ultra, and they suggest changes to both branding and camera hardware. The details appear to come from internal testing builds.

One notable point is the naming. In China, the phone is expected to launch as Xiaomi 17 Ultra by Leica, which fits Xiaomi’s current branding. Outside China, however, the watermark references Leitzphone powered by Xiaomi, hinting at a different name for global markets. Xiaomi hasn’t confirmed whether this branding will be used at launch, but the Leitzphone name lines up with a previous leak.
Model numbers also line up with this split. Xiaomi 17 Ultra variants are listed under codes 2512BPNDAG, 2512BPNDAI, and 2512BPNDAC, while the Leitzphone-powered models carry separate identifiers, including 25128PNA1G and 25128PNA1C.
The camera setup also appears to have changed since earlier leaks. Instead of a quad-camera layout, recent leaks point to a triple-camera system. The main camera is said to use a 50MP OmniVision OVX10500U (OV50X) Light Hunter 1050U sensor with a 1-inch format. It’s joined by a 50MP ultra-wide camera using Samsung’s S5KJN5 sensor and a single 200MP telephoto camera based on the S5KHPE sensor.
For reference, the Xiaomi 15 Ultra used a dual telephoto setup: a 50MP IMX858 (1/2.51-inch) sensor for 70mm shots, alongside a 200MP Samsung HP9 (1/1.4-inch) sensor at 100mm. It’s still unclear how Xiaomi plans to compensate for the missing 70mm telephoto this time.
Up front, the selfie camera is listed at 50MP, up from 32MP on the previous Ultra model. Powering the phone is likely to be Qualcomm’s Snapdragon 8 Elite Gen 5 chip, which should bring more room for AI-assisted image processing.
As always with early leaks, details could still change. That said, the watermark data suggests Xiaomi is finalizing both the camera hardware and how the 17 Ultra will be branded in different regions.
