Having this problem on my now 3rd S7 (different issues with previous 2). Tech support had suggested doing software flash. Rep was hoping to avoid going to that extreme, and he searched online for a solution. Initially worked (rep found posting that said to pause after first putting palm on the screen edge, then swipe). Worked about 3 times in the store, so I left with the phone. Went to show someone else, and no longer worked so back to the store. We did a software flash (guess it's akin to a FDR since I had to restore all my apps and settings). Tried it with no apps and no case on the phone - did nothing but go to next screen. We don't understand it at all. My 4th S7 is now on its way, and hoping that this will finally be one that works the way it's supposed to!
