hi, I may be wrong, but certainly screen brightness will affect your photograph. for examples, to get a good shot with KNFB reader, I have to remember to turn brightness right up, Normandy, it is zero. this isn't true of all camera apps, but very difficult to predict which ones it affects and which ones it doesn't. same with the screen curtain, some barcode apps don't work when the screen curtain is turned on.
