Random full screen pop up ads - S7 Edge

[AQK]

Good Afternoon Everyone

Can anyone please help me with this problem? It started about a week ago, and I am getting Random full screen pop up ads.

It mainly happens when the phone is locked and not being used. Suddenly a random video app will start playing in the background; its especially annoying when it happens in the middle of the night.

I was thinking of doing a  clean reinstall? 

Any suggestions would be appreciated, as this is driving me nuts.

Thank you

I have sent it to you how did you figure out exactly which app it was causing the problem

[Wendy11]

I read that its usually caused by the last app that you installed so I uninstalled last app and it worked

I deleted my flashlight and no success, still getting a lot of ads. How do you know which apps actually came with the phone?

You could try resetting your factory settings
