How to disable a floating right arrow button that makes FaceTime calls
Apparently, the &quot;&gt;&quot; button did seem to have something to do with Assistive Touch, despite attempts to turn that setting on/off not affecting it. That was Apple Support's thought, but something was screwed up, causing that button to exist when it shouldn't, so they had me force-restart the phone and that made it go away. I.e. We held down the power and home button (iPhone 6s plus) until the apple logo appeared in the center of a black screen. Once it fully booted back up, the &quot;&gt;&quot; button was gone.
