S7 Black Screen, but Live device. A way to force backup or fix?

[cognus]

we have two S7's, non-edge, and they have been almost bulletproof to now. I have a rooted S5 but have not modded either S7. My wife dropped hers, no breaks in the glass but it came up black after briefly displaying a partial image.
I can force reboot it, and it works. the backup 'key' lights up at times, the LED's work, and the phone receives calls [rings] but of course we can't see a thing.

Is there a fix? I've tried the reset via Vol - Power, that works to restart but no display. I've done Vol+ Power, can't see a thing. Tried Vol - Pwr Home, can't see anything so not sure what the result was. Plugged into PC but without being able to grant permission on the device, no dice.

How can I force a backup of everything? or... it may be backed up to her google account but how to reach, sans S7 display?:silly:

Hi, you can try to access the phone via samsung find my mobile website. You need internet connection at the s7 working and the logon data of your samsung account. In find my mobile there is a backup option.

Oliver, unfortunately she never setup a samsung account period. hard lesson.

Surely the forensics community has a way to get to the stored data.... I guess/think the only things missing, that were not on SD card or SIM, would be a few pictures stored in default local memory, a few downloads, and things that will not be restorable easily like Calendar entries [and a whole lot of app cache stuff that is not high value]... am I wrong?

But then there is the security aspect; even if I cannot fetch usable data, I need to nuke it all... Is there no way to mount those volumes on a pc or other? A universal "nuke everything on the blind" approach?

thank you for your help

I have also black/blank screen but all audio works, hardware buttons work. I can tap the screen and it makes a sound. Voice assistant turns on for some reason and she verifies the touches I make to the screen. She also verifies I am pressing on screen buttons. I also know this because I can turn the phone off using the power button, then on screen buttons, even though it's blank. So the screen does work, just noting visually. I have tried the power + volume down to no avail. I believe the battery has totally died as was also recommended. If anyone has an idea of what to do next...please help.

, I believe, and I'm going to try today, that we can get in Via download mode. So we'll set up adb, set the "blind" s7 in download mode and see if I can browse the file system
