I experienced this a couple times whereby my entire lock screen was hijacked and started randomly playing an advertisement video for drinking Bud Light beer, etc. I had to swipe left or right of the of the spam screen just to get to my normal lock screen. I removed many various apps, but the problem persisted. Finally, I gave up and did a factory restore to erase everything. This happened not just once, but twice. Unfortunately, I don't know exactly which app caused this problem, but I suspect it was a free radio app that I was using. I haven't installed any radio apps back onto my Note S9 after doing the factory restore, and everything has been okay again for the past few weeks.
