To remove or reduce ads on your cellphone, especially Android phones, you can follow these effective steps:

1. Identify and Remove Ad-Serving Apps

• Ads often come from third-party apps that push pop-up ads. Go to your phone’s Settings > Apps, find suspicious or recently used apps, and uninstall them to stop the ads

2. Block Ads in Web Browsers

• For Google Chrome:
  • Open Chrome, tap the three-dot menu > Settings > Site settings.
  • Disable Pop-ups and redirects and Ads to block most web ads.
• For Samsung Internet:
  • Open the app, tap the menu icon > Settings > Sites and downloads, and toggle on Block pop-ups.
  • You can also install ad blocker extensions from the Samsung Internet menu

3. Use Private DNS to Block Ads System-Wide

• On Android 9 and above, go to Settings > Connections > More connection settings > Private DNS.
• Set Private DNS provider hostname to dns.adguard.com or dns.dogguard.com to filter and block ads across apps and browsers without additional apps

4. Disable Notifications from Ad Apps and Websites

• Go to Settings > Notifications, find apps or websites sending ads, and turn off their notification permissions.
• In browsers like Chrome, disable notifications from sites that send unwanted ads via Settings > Site settings > Notifications

5. Opt Out of Personalized Ads

• On Samsung phones, go to Settings > Samsung Account > Privacy > Customisation service and turn off personalized ads to reduce targeted advertising

6. Additional Tips

• Clear your browsing data regularly to remove trackers that serve ads

• Use alternative browsers like Firefox or Samsung Internet that support ad-blocker extensions

• For email ads, use the unsubscribe link at the bottom of promotional emails to stop receiving them

By combining these methods, you can significantly reduce or remove ads from your cellphone experience.
