Back Camera Image Stream does not work

[Bingrong89]

Hello, thank you for the wonderful free application!
I have been able to get it to stream most of the sensor data, except for the back camera image stream. The app does not give any feedback on any failure, nor am I receiving anything on the server side.
I am using android version 12 on a Samsung Galaxy A53.
If possible, could you kindly give any tip on what might have gone wrong?
Thank you.

I believe the app may not have been given permission to access the camera. Can you check the app permissions and ensure that this access exists?
