When i receive a notification in a form of app badge (any app) and after closing very same app i get “ghost effect” in the form of badge re- appearing for a second or so and then disappears again. With the help of my friend and changing all the option (i also did factory reset since it was irritatibg) i found out exact culprit . When Navigation bar (in settings/display) is set to "full screen gestures" this then occurs. Obviously a bug which should be solved by Samsung or Google android.
