Constant pop ups

[Le69]

How do I stop pop ups on my fone? They annoy me..

It will be a recently added app causing these adverts.

You can see which by going to settings, apps, permissions and looking in the menu for that page for "special access"

The offending app will be in the "draw over other apps" section.

Pop-ups are caused by some 3rd party app you have installed. You should identify the app(s) yourself by uninstalling those you have installed recently.
