Webcam not working on galaxy a9

We are using tf 2.9.1 and 2.11.1 in unity project.
The camera worked normally on almost all devices, and the BlazePose function works without any problems.

However, in the Galaxy a9 model (sm-a920n), webCamTexture.didUpdateThisFrame always maintains a false value, so texture isn’t created.
No matter which version of tensorflow we use, We cannot use the camera on that device.

Hopefully someone can check the issue on that device and give me a solution, Please.

Thank you.
