To stop ads on your phone, especially Android devices, you can take several effective steps:

1. Identify and Remove Problematic Apps

• Ads often come from third-party apps that you have installed. Identify apps that frequently show pop-up ads by checking which apps were recently active in the Google Play Store under "My apps & games" > "Installed" > "Last used."
• Uninstall apps that you suspect are causing ads, especially if you haven't used them recently

2. Manage Ad Settings on Your Phone

• For Samsung phones, you can opt out of personalized ads:
  • Go to Settings > Samsung Account > Privacy > Customisation Service and turn it off to reduce personalized ads and some ad frequency

• On Android generally, you can disable ad personalization by going to Settings > Google > Ads and selecting "Opt out of Ads Personalization"

3. Block Ads in Browsers

• In Google Chrome:
  • Open Chrome > tap the three-dot menu > Settings > Site settings.
  • Disable Pop-ups and redirects and Ads to block intrusive ads on websites.
• Alternatively, use browsers like Samsung Internet or Firefox that support ad-blocker extensions

4. Disable Notifications from Ads

• Ads can appear as notifications. To stop these:
  • Go to Settings > Notifications.
  • Identify apps sending ad notifications and toggle off their notification permissions.
  • You can also long-press a notification and disable notifications for that app

5. Use Private DNS to Block Ads System-wide

• Set up Private DNS to block ads across apps and browsers:
  • Go to Settings > Connections > More connection settings > Private DNS.
  • Select "Private DNS provider hostname" and enter dns.adguard.com or a similar DNS provider that blocks ads.
  • Save and exit. This method blocks many ads without needing root or extra apps

6. Install an Ad Blocker App

• Apps like AdGuard or Blokada can block ads throughout your device, including apps, browsers, and games.
• AdGuard works on both rooted and unrooted devices and also protects your privacy by blocking trackers

7. Manage Email and Website Ads

• Unsubscribe from advertising emails by clicking the "unsubscribe" link at the bottom of promotional emails.
• Disable website notifications that send ads by going to your browser settings and turning off notifications from unwanted sites

Summary

By removing ad-heavy apps, adjusting ad personalization settings, blocking ads in browsers, disabling ad notifications, using private DNS, and optionally installing ad-blocker apps, you can significantly reduce or stop ads on your phone
