Don't you see it??? Lolwhat am I looking at?
?Samsung still hasn't fixed this bug in their launcher, which has existed (and I've personally witnessed) on every Galaxy S device since the Galaxy S3.
Guessing it's from some theme or app. Have never seen anything like it.
What is this click bait...
Try a different theme. I never use the stock theme so I never see this "bug".
I had this issue on my S8+ and my S9+. Not enough of an issue to complain tho. Just tap on a blank space somewhere on the screen & it goes away. No specific app, and it happens with stock and downloaded themes.
