OP doesn't use any Hassleblad optics. It's more of the trademark arrangement and possibly extending to colour science/digital filter etc. But those are also very vague.
When Huawei had partnered with Leica in the early days, Leica did had a much higher say on the hardware of the camera and it's implementation.
In neither the above case, any optics that is to say sensor level involvement was there.
Neither Leica/Hassleblad make sensor for smartphones.
Sony/Omni vision and to some extent samsung are responsible for mass producing camera sensor for almost all smartphones.
Smartphone camera there days are more about computation photography and software. They have reached the physical saturation point
Dream Cars for Girls in terms of hardware.
