Hello there this is my first post and I think I got it…
I had the same problem last year. No matter what theme I bought from the app store I could still see it. So what I did was turned on the the “DEVOLOPER OPTIONS” on my tablet. The reason why I found this better for me it was complete customizing . I removed pretty much all icons from my home screen… including the time, wifi, NFC, battery icon, head set connect. I did read that you have tried playing with settings but this will do you can l take whatever you want off . Hope this works @rasch. Hit your BUILD NUMBER 7 OR 8 TIMES AND YOUR GOOD.
