Thank you for the great app, it's better than the stock camera in many ways already! I've read this thread and I don't think this has been asked: is it possible for you to enable higher ISO values than the current ISO400 or is this limited by the camera driver? I read from jolla together that ISO640 was possible earlier on the stock camera. I would not mind even higher settings, as the camera is nearly unusable in normal indoor light conditions when taking pics of my kids who do not stand still for a fraction of a second.
