+18 Samsung S9 Black Screen Blue Light Ideas. Does anyone know what this might mean please? Web i have the samsung galaxy s9 plus and every now and again a small blue light flashes up in the top left hand corner of my screen.
Press & hold both volume down and power button at the same time. It is not the led indicator, it is on the actual screen. It has a blue flashing light but sometimes a green flashing light.
