But for a few days on my phone no matter which app I have open popup advertising. I'm not on the internet or when it comes but On Netflix and there appears at once or without I press anything, I'm gemoved on an English website. Can someone tell me how to turn it off again?
Any app that runs in the background, does that. You have somehow captured you…
So look and uninstall it. Make a virus and adware scan etc…
Which APKs or software outside of the Playstore you've recently downloaded?
Could get away with it
May be adware just uninstall the last apps and watch from when the problem is no longer there.
Sounds like adware. Run a virus scan through then the problem should be solved
