Use Android Camera Player to capture your phone's camera. I mentioned that when the image is stored on your phone, it will be a black PNG

I used the Android Camera Player plugin to capture the phone’s camera image into the texture. I tried to capture one of the frames and save it in a file, but it was saved as a black PNG

The file on the phone is black PNG

This is the step to store the PNG

Hope to have a brother to help me answer!
