Yeah. I finally figured it out. I had that screen saver for 2 days before I noticed the overlapping symbols but them must have been there the whole time. It is because it's a screenshot. Thanks.
I have the Note 10+ and I just got the update this morning. I have AT&T. Now my home screen has overlapping symbols at the bottom of the screen. Anyone know what they are? I can still use the buttons like before. Thanks!
