Phone playing little kids videos on its own in the middle of the night

[Android Central Question]

I have a Samsung Galaxy s7, upgraded to whatever the most recent Android system is. Past couple days I noticed in the morning that the Samsung internet browser was open to youtube and some little kids video. Figuring it was malware attached to that app, I deleted it and downloaded Firefox. Well now it's 5 am and my phone just woke me up blaring a little kids video through youtube in the Firefox app.

Neither Malware Bytes or Avast have found any malware and I don't have the funds atm to spend on the premium versions.

So...yeah. Help please?

Does it persist in Safe Mode?

Sounds like the stuff horror films are made of.

Not to be into a conspiracy theory, but honesty it sounds like someone has hacked your phone and is controlling it remotely.

If your phone is on WiFi at your house, I would try turning off the WiFi connection on your phone to see if the problem stops.

If it does stop, then someone has hacked your home WiFi.

If the problem doesn't stop, then it is either Malware or someone is hacking your phone and controlling it remotely.
