Has anyone had the same problem I had were your volume panel does not come off after you adjusted it,well I just found the solution today,you just have to wait patiently for sometime or maybe leave it over night it will eventually come off

Thank you Samsung for taking your time to reply and I appreciate your help

Did you try swiping up from the bottom and clicking the back button?

Try to go to the settings from the settings button on the volume display and then exit settings and it is back to home,usually works.

I had tried all that but nothing happened
