Enable USB Debugging on a S7 with blank screen

[Android Central Question]

My gf broke her galaxy s7 by dropping it. The screen is totally black, but the phone starts up and what not ( can hear the noises). I had the insurance through AT&T so the replacement phone was only $112. Anyways is there anyway to enable USB debugging on the phone from the PC. I have downloaded minimal Adb and fast boot, but when I open up the prompt and typed in "ADB shell." It said no devices or emulators found. The phone is showing up as a G930A on my PC, but when I goto access it everything is blank. I have tried Dr fone (does not support S7) and smart switch. Is there anyway to get into this phone. I am trying to make sure I have all her info saved before shipping the phone back.

At very least, you'd need a working screen plugged in temporarily to enable USB debugging, then to allow that PC to access the phone. You can't do those thigs in software.
