How to Turn Off Ads on My Phone (Android and iPhone)

Ads on your phone don't all come from the same place. Knowing how to turn off ads on my phone starts with identifying which type is the problem.

This guide covers browser pop-ups, notification ads, personalised tracking, and app-generated ads — each with its own fix.

The Short Answer: What Controls Which Ads

Different ads need different fixes. Here's a quick reference before the step-by-step sections below.

Why Do Ads Keep Appearing on Your Phone?

Most people assume the phone itself is pushing ads. In practice, that's rarely the case. The operating system doesn't serve ads directly.

What does serve them is a mix of apps you've installed, websites you've visited, and account-level tracking tied to your Google or Samsung account.

Ads from Third-Party Apps

Free apps are funded by advertising. When you install one, you're typically agreeing to see ads as part of the deal. Some apps display ads only inside themselves. Others, particularly lower-quality ones, push ads to your home screen or notification bar. That second type is the one most people want gone.

Browser Pop-Ups and Redirects

These come from websites that show ads aggressively or have been accidentally granted notification permission. They're not a virus. They're fixable in under a minute once you know where to look.

Personalised Ad Tracking

Google and Samsung both track topics of interest based on app usage and browsing. This data shapes which ads you see.

Turning off personalisation won't stop ads from appearing — it stops them from being targeted to your behaviour specifically.

How to Turn Off Ads on My Phone in the Browser

Google Chrome (Android)

1. Open Chrome and tap the three-dot menu in the top right.
2. Go to Settings > Site Settings.
3. Tap Pop-ups and redirects and set it to Blocked.
4. Go back, tap Ads, and set that to Blocked as well.

This stops most intrusive ad formats across websites you visit through Chrome. In practice, users who apply both the pop-ups and ads toggles together report noticeably fewer interruptions compared to blocking pop-ups alone.

Samsung Internet

1. Open Samsung Internet and tap the three-line menu icon.
2. Go to Settings > Sites and Downloads.
3. Toggle on Block pop-ups.
4. Return to the main menu and tap Ad Blockers.
5. Download one of the listed ad blockers from the available options.

Samsung Internet is the only major mobile browser that natively supports downloadable ad blockers. If reducing web ads is a priority, this is the most effective browser-level option on Android.

Safari (iPhone)

1. Open the Settings app.
2. Scroll down and tap Safari.
3. Under the "General" section, toggle on Block Pop-ups.

Safari's built-in Fraudulent Website Warning option sits nearby and is worth keeping on as well.

How to Turn Off Notification Ads on Your Phone

Notification ads are easy to overlook as a category. They look like normal alerts but are coming from apps that have been granted notification access and are using it to push promotional content instead.

In practice, many users don't realise they've granted notification permission to a website or app during a quick install or a site visit. Revoking that access is usually the fastest fix.

Android: Disable Notifications from a Specific App

If an ad just arrived as a notification, long-press it and tap the toggle to turn off notifications for that app immediately.

Through settings:

1. Open Settings > Notifications.
2. Find the app under "Recently Sent" or scroll the full list.
3. Toggle off notifications for that app.

Android: Stop Website Notification Ads in Chrome

1. Open Chrome and navigate to the website sending notifications.
2. Tap the padlock icon at the top left.
3. Tap Permissions > Notifications.
4. Set it to Don't allow.

iPhone: Disable App Notification Ads

1. Open Settings > Notifications.
2. Find the app you want to silence.
3. Tap it and toggle off Allow Notifications.

How to Turn Off Personalised Ads

This is a separate layer from pop-ups and notifications. Personalised ads use your activity data to decide what to show you. Opting out changes the targeting, not the volume.

You'll still see ads in free apps — just not ones built around your browsing habits.

Android: Google Ad Privacy Settings

1. Open Settings and tap Google.
2. Tap All Services.
3. Under "Privacy & Security," tap Ads > Ads Privacy.

From here, manage three options:

• Ad Topics: Android tracks interests from your apps. Toggle off Allow Ad Topics to stop this. Google deletes topic data automatically after four weeks, but opting out stops collection entirely.
• App-Suggested Ads: Apps can store ad suggestions about your preferences. Toggle off Allow App-Suggested Ads to disable this.
• Ad Measurement: Limits data sharing used to measure ad performance. Toggle off Allow Ad Measurement to restrict this.

Samsung Devices: Turn Off the Customisation Service

1. Open Settings and tap Samsung Account.
2. Go to Privacy > Customisation Service.
3. Toggle off the customisation service.

This stops Samsung from using your data to personalise promotions within Samsung apps. It reduces how targeted those ads are, though it doesn't remove them entirely.

iPhone: Apple Personalised Ads

1. Open Settings.
2. Tap Privacy & Security > Apple Advertising.
3. Toggle off Personalised Ads.

How to Stop Pop-Up Ads Coming from Apps

If ads are appearing over your home screen or interrupting other apps, a recently installed third-party app is almost certainly the cause. The phone is not malfunctioning. One of your apps is behaving aggressively.

Identify Which App Is Causing the Pop-Ups

1. Open the Google Play Store.
2. Tap your profile picture, then Manage Apps & Device > Manage.
3. Sort by Last Used.

Look for an app that was active recently but that you didn't intentionally open. That's a strong indicator.

Remove the Offending App

Once identified, go to Settings > Apps, select the app, and tap Uninstall. Restart the phone afterward.

If you can't narrow it down, Android's Safe Mode disables all third-party apps temporarily. If the pop-ups stop in Safe Mode, one of your installed apps is responsible.

To enter Safe Mode on most Android phones: press and hold the power button, then long-press Power Off until the Safe Mode restart prompt appears.

Enable Google Play Protect

1. Open the Google Play Store.
2. Tap your profile picture, then Play Protect > Settings.
3. Toggle on Scan apps with Play Protect.

Play Protect scans installed apps for harmful behaviour and runs quietly in the background without noticeable battery impact.

As reported by TechCrunch, Google Play Protect identified more than 27 million new malicious apps in 2025 alone, warning users or blocking the apps from running entirely.

What You Can't Fully Turn Off

Ads inside free apps are part of how those apps are funded. According to Wikipedia, in-app advertising accounted for roughly two-thirds of total mobile app revenue in 2025. No system setting removes those ads without paying for an ad-free version or uninstalling the app.

That's not a flaw — it's the revenue structure.

What you can do is separate the problem into parts. Block pop-ups in your browser. Revoke notification access from apps that misuse it.

Opt out of personalised tracking. Remove apps that push ads outside their own interface. Each step is real and measurable.

Conclusion

Different ad types need different fixes. Tackle browser pop-ups, notification permissions, personalised tracking, and rogue apps as separate problems.

You can significantly reduce the ads you see — but in-app ads from free apps will remain as long as the app is installed.

Frequently Asked Questions

Will Turning Off Personalised Ads Mean I See Fewer Ads?

Not necessarily. Opting out stops ads from being targeted to your data. It doesn't reduce the number of ad slots in apps or websites. The volume stays the same — the relevance changes.

Can Ads on My Phone Signal a Harmful App?

Pop-ups appearing over your home screen or other apps often point to a rogue third-party app. Uninstalling recent apps and running Google Play Protect usually clears it up.

Does Turning Off Ad Tracking Stop Apps Collecting My Data?

No. Opting out of Google's ad privacy settings limits how data is used for targeting. Apps still collect data under their own privacy policies.

How to Turn Off Ads on My Phone: Is There One Setting?

No. Ads come from browsers, apps, notification permissions, and account tracking — each needs its own fix. There is no master off switch in Android or iOS.

Do Ad Blockers Work on Mobile Phones?

Browser-based ad blockers work for web page ads. Samsung Internet supports downloadable ad blockers. Chrome on Android relies only on its built-in pop-up and ads settings. Ad blockers don't affect in-app advertising.
