I know you mentioned the a71, but on my a70 when I activated the 3:4h mode , the flash option changes from a pop up selection of auto, on, off to just changing between auto and off, without the popup option .
So you're not even seeing the flash symbol change from on to off ?
Flash works everywhere exept camera in 3:4H mode. This make 64 Mp camera useless in low light! Why Samsung advertise 64Mp camera when i can't use it ! I'm so disappointed 😔
Same with me on the a71. All the reviews on youtube showing that you can't use 64mp with flash when on 3:4H. I don't know why but it's kinda disappointing.
