Why my phone screen is black? SAMSUNG 6

[Esdras J]

It's a Samsung Galaxy S6. I see nothing at all. I have worked to unblock it, take pics, take screenshots and even I have made it to activate the hot spot, but all I have done it by calculating. I see nothing. I have had a WhatsApp video call, they can see me, but I see all black. So the screen is full black but my cellphone is working perfectly. I tried the tricks that I found on the web: volume down and lock button, volume down button-lock button-home button to go to recovery, but I am sure it went there but I just could not see on the screen anything. The back key still makes light and also the blue light and the red and when I am charging it.

Any help?

It sounds as if your screen went bad. It's time for a trip to the repair shop.
