How to Fix Galaxy S7 Black Screen Issue and Recover Data

“I have my S7 for 4 days. Everything have been fine until this morning, when the screen went black and won’t be turn on. But the device is cool to the touch, the speaker worked, I could heard beeps while hitting some buttons, the bottom buttons would occasionally light up, and the phone would sound off when I called myself. Clearly to me is the phone was still operating, it was just the screen turns black.”
