Huawei’s upcoming Mate 90 series is already attracting attention, and the Mate 90 RS Ultimate Design could bring back one of the company’s most recognizable premium phone ideas. Recent leaks suggest that Huawei may be preparing a major change to the rear camera design while also continuing to use ceramic materials for the top-end model.
The information is still based on leaks and early reports. Huawei has not officially confirmed the Mate 90 RS Ultimate Design, its final appearance, or its specifications.
A Classic Mate Design Could Return
The biggest design rumor around the Mate 90 RS Ultimate concerns the rear camera area. Recent reports suggest Huawei may move away from the octagonal camera shape used on recent RS Ultimate models and return to a square camera layout inspired by the older Mate 20 series.
The possible change would give the Mate 90 RS a very different look from the recent Mate RS generations. The square camera design could also create a clear visual connection with Huawei’s earlier flagship phones.
This does not mean the Mate 90 RS will simply copy the Mate 20. The leaked information points to a modern version of the older design idea, with the camera hardware and overall body expected to be updated for the new generation.
Ceramic Could Remain a Key Part of the RS Model
The possible return of a ceramic rear panel is another reason the Mate 90 RS Ultimate Design is getting attention. Recent reports from China claim that the RS version could use a nano-microcrystalline ceramic rear panel, while regular versions of the Mate 90 series may use different materials.
Ceramic has already been part of Huawei’s premium RS phone design. The Mate 60 RS Ultimate Design, for example, used a ceramic rear cover together with a metal body design.
That makes a ceramic rear panel on the Mate 90 RS believable as a continuation of Huawei’s high-end design approach, but it should still be treated as unconfirmed until Huawei provides official specifications.
What the Possible Rear Design Could Look Like
The reported design change is mainly about the camera module rather than a complete change to Huawei’s premium phone identity.
Recent leaks suggest the company may use a square camera housing instead of the octagonal shape that has appeared on recent RS Ultimate models. The camera area could remain large because the RS model is expected to focus heavily on photography.
The rumored design can be summed up in a few points:
- A possible square rear camera module inspired by the Mate 20
- A possible return of ceramic material for the RS model
- A more traditional and symmetrical rear appearance
- A new design around updated camera hardware
These details come from leaks rather than Huawei’s official product information, so the final phone could look different.
Why the Mate 20 Connection Matters
The Mate 20 series was one of Huawei’s most recognizable phone generations. Its square camera layout became closely associated with the Mate 20 Pro and other models in that family.
Bringing back a similar camera shape would give the Mate 90 RS a connection to Huawei’s older design language while allowing the company to create a new premium look.
The change would also be noticeable because Huawei’s recent RS Ultimate phones have used an octagonal camera design. A move to a square module would therefore be more than a small styling change. It would mark a new direction for the RS line.
Other Mate 90 RS Details Are Still Unclear
There are several other reports about the Mate 90 series, including claims about new Kirin processors and camera improvements. Some recent leaks suggest the higher-end Mate 90 models could receive newer Kirin chips developed for 2026, with the RS Ultimate Design potentially getting one of the more powerful versions.
However, exact processor names, camera specifications, battery capacity, display details, pricing, and release information should not be treated as confirmed at this stage.
Some websites have published detailed specification lists for the Mate 90 RS, but these include information that has not been confirmed by Huawei. For that reason, those figures should not be confused with official specifications.
What Could Make the Mate 90 RS Stand Out
If the leaks are accurate, Huawei could be combining an old design idea with newer hardware. That would give the phone a different identity from both the regular Mate 90 models and earlier RS Ultimate phones.
The combination of a square camera module and ceramic rear panel could also make the phone visually distinctive. Ceramic has traditionally been used on premium phones because it offers a different feel and finish from ordinary glass.
At the same time, the camera redesign could give Huawei more room to arrange multiple camera components. Earlier reports have suggested that the Mate 90 series will receive camera improvements, although the final hardware has not yet been confirmed.
Final Take
The Huawei Mate 90 RS Ultimate Design could bring back two ideas that have been important to Huawei’s premium phones: a ceramic rear panel and a distinctive camera design.
The most interesting rumor is the possible move from the recent octagonal camera housing to a square module inspired by the Mate 20 series. Recent leaks also point to ceramic being used again on the RS model.
For now, none of these Mate 90 RS design details should be considered final. Huawei has yet to officially reveal the phone, so the actual rear design, materials, cameras, hardware, price, and release plans could still change.
