Starting yesterday, I have been having something weird, that I have never seen, happen. It has happened 4 times in the past 24 hours. The first time, I didn't actually notice when it appeared. The second time, I think it might have happened when I opened Instagram, but I'm not sure. The third time I'm almost positive it happened when I opened Snapchat. Now the fourth time I wasn't opening anything, but I believe it was while my phone was updating the Snapchat app. The 2 times yesterday it was on wifi (no other wifi problems were noticed at that time) and 2 times were today on Verizon data.
Nothing I seem to do makes it go away, other than restarting the phone, or it eventually disappears on its own. The things I have tried to make it go away are:
- closing all open apps
- turning wifi off then on
- turning on airplane mode
- reopening the app that seemed to cause the problem
I'm attaching a screenshot of what it looks like.

Any help would be great!
