With latest update 23DEC photos work for me, with inbuilt Kamera, but also with Footej Camera and Open Camera.
Both phone cameras work.
In open camera I had to enable Android-5-Camera2-API in settings.
What about flash? Is it in synch? Exposures taken in the dark, are they ok?
What about taking two pictures in a row? Isn't every 2nd picture still green?
