Volume problem on Iphone 7

[mvarenaz]

When I run spotify in Background on Iphone 7, the volume control appears suddenly when I am using any app.. And it keeps showing all day long no matter what I am doing on Iphone.

I only linked it today to being a spotify problem. I booked into an apple store thinking it was my down volume that had the issue.

Thought i'd search google... and sure enough others are getting the problem too.

I have Iphone 7 plus - updated fully. It seems to only go down - not up for me. If you sit there and keep turning the volume up and down continuously while watching the icon readout on the phone, you will see the little "squares" flicker and glitch
