At 50M or 64M high resolutions (depending on device), it only lets you select automatic flash. What is the point of this restriction? It seems completely arbitrary and unreasonable.
In comparison, Xiaomi allows manual flash at high resolution, and even continuous light, which Samsung doesn't have at all in photo mode. But to Samsung's credit, they have added the ability to turn the light on and off during (not just before) a video recording, which Xiaomi does not have.
