HW issue would be my first guess for the screen if it wasn't for the USB issue and forced update all on the same day. Still its likely. Probably coincidental timing. But I would like to be able to roll back the update and see and fix the USB issue perhaps. If it comes to changing the screen, I will try that myself but I do a lot of that kind of thing.

There are several articles on recovery mode and factory reset but its not clear;
Does a reset to factory actually roll back the build and kernel or just data and settings.? I suspect its the data and settings but I still don't know.
After running the graphics test from the recovery mode, I am more convinced the display issue is HW. I'll let you know how the replacement goes.
The USB issue was caused by forced updates to both the Samsung S7 build and Windows 10 that occurred in the last week. While the two communicated flawlessly prior to these update, after the updates the connection would occasionally work but often would not show the device at all, show directories as empty or show partial file lists. I believe the, perhaps intentional, effect was to drive customers to interface through their cloud services. You can come to your own conclusions on why they would do that.
The solution to the USB issue is to install , in Windows 10, "Samsung Android USB Driver for Windows" which can be found at "
Support | Samsung Developers"
While this driver is described on the site as; "You need the driver only if you are developing on Windows and want to connect a Samsung Android device to your development environment over USB", It does not appear to grant root permission or provide any more access to the phones files than was previously granted. I have seen this driver on non developer sites as well. Still I would warn anyone connecting trough USB with or without this driver to not delete or alter files or directories you are not familiar with. You wont harm anything by looking.
For those unfamiliar with the mobile phone file layout;
There are generally two devices listed in the "Galaxy" device on windows; "Phone" (the standard phone memory) and "Card" (the extra memory card you added).
Depending on your settings, the files you are probably interested in could be on both.
On my phone, My Documents and Downloads can be seen from the root. for pictures and video, look under DCIM/Camera.
Thanks
