I am thinking of switching to the Galaxy Fold (original) since it is getting to a affordable price on Amazon, but i have a few questions about an updated Fold. Did the original Fold get updated to have Wireless Dex? Can you run two apps on the interior screen with the screen folded at 90 degrees? (or does the screen turn off at that angle?) Can you run windowed apps on the interior screen and move them around or is it stuck at opening 2 to 3 apps at a time? What is the maximum resolution that Dex can display out of it? Thanks for any help.
