I have LineageOS on my phone and noticed the media player has the wavy progress bar on it. Not only that, a lot of music players also have it and lowkey I personally don’t like them. I find it hard to position where I actually want to be in the song and I just don’t like the constant movement. I rather a normal progress bar but that just a personal choose.
Ah, thanks for sharing how to remove it. Though, I never realized how choppy it looks to maneuver my phone without animations lol. I’ll keep them on because the one benefit is not outweighing that.
