Step by step

1. 

   Block pop-ups in Chrome

   In Chrome tap the three dots, Settings, Site settings, Pop-ups and redirects. Choose Don't allow sites to send pop-ups and use redirects. Ours was already set like that.

   Done

2. Stop site notifications

   Ads that appear as notifications come from a website you allowed. In Chrome, Settings, Notifications, switch off sites you do not know.

   Done

3. 

   Find apps that draw over others

   Open Settings, Apps, then the three dots and Special access, Appear on top. This lists apps allowed to show things on top of other apps; we blurred our list.

   Done

4. Switch off unknown apps

   Switch off any app there you do not recognise or did not install yourself. If ads continue, uninstall the newest app installed before they started.

   Done

5. 

   Scan with Play Protect

   Open Settings, Security and privacy, App security, Google Play Protect and tap Scan.

   Done

6. Clear Chrome site data

   If one site keeps opening, remove its data in Chrome under three dots, Delete browsing data.

   Done

About this guide

Pop-up ads on a phone come from one of three places: a website in the browser, site notifications you allowed, or an app that may draw over other apps. Each has its own switch. We only looked at these screens on our phone and changed nothing.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ.

Good to know

Google explains how to remove unwanted ads, pop-ups and malware in Chrome on its help page.

In short: Chrome: Site settings, Pop-ups and redirects, Don't allow. Chrome notifications off for unknown sites. Settings, Apps, Appear on top: switch off unknown apps. Play Protect scan.
