It's like a form of ..graphical trailing..shadows are moving with it too..it's just very noticeable and atrocious when it's dark scenes (which the whole CINEMA is)
Yes, this is a limitation of the panels used on the phone. Many are calling this "black smear", as it usually happens with darker scenes, or with contrasting light/dark colors. I believe the software does try to mask it a bit, but unfortunately it won't go away completely.
