Pretty sure I asked this last year or year before already, and it's a small, aesthetic thing, but I don't understand why the volume slider background is not transparent on most apps but so far the only one I've seen is the Disney+ app. It looks so much cleaner to have a mostly transparent background on the volume slider, much less intrusive I found.With GoodLock I can almost do the same thing, but the transparency is not dynamic, it basically takes a snapshot of what's behind and blurs it. Which is ok static content but looks so bad when watching videos (which is typically when I tend to adjust my volume).
But if Disney can somehow do it, I'm sure Samsung could just at least add an option if not making it standard all the time.
