Step by step

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
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.
To stop all of them, switch off Allow notifications on Chrome's page in the phone's Settings, Apps, Chrome, Notifications. Ours was on.
Done
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.
Done
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.
On ours Android Auto, Cross-Device Services, Facebook and Galaxy Themes were off; the others were on.
Done
Scan with Play Protect
Open Settings, Security and privacy, App security, Google Play Protect and tap Scan.
Done
Clear Chrome site data
If one site keeps opening, remove its data in Chrome under three dots, Delete browsing data.
Pick a time range and tap Delete data. We tapped Cancel.
Done

A site has no Permissions in Page info Google says that if you do not find Permissions after tapping Page info next to the address, that site does not have notifications turned on, so the ads are coming from somewhere else. Source: Remove unwanted ads, pop-ups & malware

If this does not work

Ads keep coming after you switch apps off Google's fix is Safe mode: press and hold the power button, touch and hold Power off and confirm. Then remove recently installed apps one at a time, restarting normally after each, until the ads stop. Source: Remove unwanted ads, pop-ups & malware
Play Protect finds nothing Google says to make sure Scan apps with Play Protect is on in the Play Store, under your profile picture, Play Protect, Settings. Source: Remove unwanted ads, pop-ups & malware

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.

Steps 2, 4 and 6 are from the same phone after its One UI 9 update (Android 17).

Good to know

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