Popup ads during unlocking, unable to identify souce

[AC Question]

Hi, I recently got Android update for 7.1.1 and after that whenever I unlock my keypad I get an add pop-up in the center of the screen and when I click on it it opens up chrome browser and redirects to zerodirect12.Com and some other sites.

I uninstalled all apps I had installed recently and yet I am unable to find the source.

I have not installed any app outside Google play and even anti virus apps didn't detect anything.

If it's by some app I am sure Google would have blocked it by now from Google play. Now that isn't blocked I guess it's from Google's latest update itself.

And also that it's detecting my screen unlock that means it must be having device administrator enabled but I don't see any app under that which confirms again that it must be from Google.

Is it only me or someone else is also facing the same?

Any help would be appreciated.

Thanks.

Welcome to the forums. Try clearing the browser data. You will have to set everything back up, but it should clear the ad that is popping up.

I did, but still the same thing. But how can browser pop-up ad on home screen?

Does the trouble persist in Safe Mode?
