getting rid of video thumbnails

trying to get rid of thumbnails or popups on phone.

Whenever I get on the phone, just touching the right side of screen brings these annoying pop ups up.
If you hit the plus sign on the bottom of them they'll show video snaps.

I followed the prompts for the j3, twice in fact, got the same bothersome problem, tried shutting of safe mode but I couldn't find it.....nowhere was this stated.
So I don't even know if I am or ever were in "safe mode"! beyond frustrating.
 
Rebooting normally will exit Safe Mode.

So you're saying that the sidebar still appears in Safe Mode? That would suggest it's actually a system feature, or related to some app Samsung preinstalled on the phone.

Can you tell us what these "video snaps" are? Are they ads?
 
no, theyre icons of facebook, instagram, Twitter and chrome.....as shown in the screen shot above. turning the page you get video clips, like from youtube.
left side bottom corner are ads in page- like form.

Welcome to the forums. It's strange that you get the same in safe mode. Try this, open your recent apps while that side bar is on your screen and take a screenshot to see which card/app is the last one. That could give us a clue of what's going on.
 
maybe I wasn't clear.....it isn't a sidebar, it covers the page and I can't open anything except to click on one of those icons or go back. those are the choices. I really appreciate your attempts, tho', thanks!
the screen shot above on a previous message shows it's the whole page that is dark except for the app icons on the right and small pages on lower left which I notice doesn't even show up on the screen shot.

Yeah, I understood that, but you still should be able to open your recent apps overview using your navigation buttons.
 
I'm simply trying to get rid of the thing. It's a nuisance and I'm not aware of how it got there. it blocks the screen when I touch that right side.

Yes, we get that, we are just trying to help you to find which app or stock feature is causing that issue.
