How to Stop Ads on My Phone: Android & iPhone Step-by-Step Guide

Ads on your phone come from three main sources: apps you've downloaded, browser permissions you've granted, and data-tracking systems that personalise what you see. If you're asking how to stop ads on my phone, the answer starts with removing or auditing recently installed apps, then adjusting browser and notification settings, and finally turning off ad personalisation in your device's privacy settings.

Why Am I Getting Ads on My Phone?

Most people assume their phone itself is the problem. It rarely is.

Apps are the most common cause. Free apps make money by showing ads, and some push those ads aggressively — beyond their own interface and into your notification tray or home screen. That's the line between annoying and genuinely problematic.

Ads Caused by Apps You've Downloaded

When you install a free app, you're typically agreeing to see ads as part of the deal. Most stay within their own screen. Some don't.

As reported by TechCrunch, security researchers have found large batches of apps on Google Play that serve full-screen ads, hidden ads, and ads running in the background — often in popular utilities and games that users had no reason to distrust. If ads are appearing when an app isn't open, that specific app has crossed into territory that most platforms technically prohibit — but enforcement is inconsistent.

Ads Served Through Your Browser

Browser ads are separate from app ads. If you're seeing pop-ups or redirects while browsing, the issue is usually a site that has pushed notification permissions to your browser, or simply a site running heavy ad scripts with no blocker in place.

Notification Ads From Apps and Websites

This one catches people off guard. A website you visited once can send you ads via browser notifications if you tapped "Allow" on a permissions prompt — sometimes without realising what you were agreeing to. Apps can do the same through their own notification channels.

Lock Screen and Home Screen Ads

These are less common but more disruptive. They usually come from a specific app — often a free wallpaper, news, or utility app — that is running in the background and using your lock or home screen as ad space.

Personalised Ads Based on Your Data — and What Turning Them Off Actually Does

Worth being clear about this upfront: opting out of ad personalisation does not stop ads from appearing. It stops ads from being targeted to your interests. You'll still see ads — they'll just be less relevant to you. If reducing the volume of ads is the goal, personalisation settings alone won't get you there.

How to Stop Ads on My Phone: First, Identify Which Type You're Dealing With

Before working through every setting on your phone, it helps to identify which type of ad you're actually dealing with.

Ad Type	Where It Appears	Most Likely Cause	Fix
Pop-up ads	Over app or home screen	Aggressive or adware app	Identify and remove the app
In-app ads	Inside a free app	App's revenue model	Upgrade within the app or switch apps
Browser ads	Inside Chrome or Safari	No blocker / site scripts	Browser settings + content blocker
Notification ads	Notification tray	App or website permission	Revoke notification access
Lock screen ads	Lock screen	Background app or manufacturer skin	Device settings or app removal
Personalised ads	Across multiple apps	Ad ID and data tracking	OS-level privacy settings

How to Stop Ads on Android

Step 1 — Identify and Remove the App Causing Pop-Up Ads

This is almost always the right place to start. If ads are appearing outside of a specific app — on your home screen, lock screen, or while using another app — a background app is responsible.

How Safe Mode Helps (and How It Works)

Safe mode temporarily disables all third-party apps while keeping your core system running. If the ads stop in safe mode, a downloaded app is confirmed as the source. To enter safe mode: press and hold the power button, then press and hold the "Power off" option on screen until a "Reboot to safe mode" prompt appears.

How to Find Recently Active Apps via Google Play

Open the Google Play Store, tap your profile icon, go to Manage apps & device, then Manage, and sort by Last used. Any app you haven't opened recently but appears active is worth investigating.

How to Uninstall Suspect Apps

Go to Settings > Apps, find the suspected app, and tap Uninstall. Remove one app at a time, then restart normally to check if the ads stop before removing the next.

Step 2 — Remove or Reduce In-App Ads

In-app ads are part of the app's design. They're not a malfunction.

Paying to Remove Ads Within the App

Most ad-supported apps offer a paid upgrade — either a one-time purchase or a subscription — that removes ads. This is the most straightforward fix if the app is one you use regularly.

Finding an Ad-Free Alternative App

If the app doesn't offer an ad-free version, or the price isn't worth it, searching for an alternative with no ads or a cleaner ad model is a practical option. In practice, many users find a comparable free app with less aggressive advertising simply by checking reviews that mention ads.

Step 3 — Block Pop-Up Ads in Google Chrome on Android

Blocking Pop-Ups and Redirects in Chrome Settings

Open Chrome and tap the three-dot menu in the top right. Go to Settings > Site settings > Pop-ups and redirects and make sure this is turned off. Then go back to Site settings > Ads and turn that off too.

Revoking Website Notification Permissions in Chrome

In Chrome, go to Settings > Site settings > Notifications. Any site listed there has permission to send you notifications. Tap each one you don't recognise and select Block.

Step 4 — Manage App Notification Permissions on Android

Go to Settings > Notifications > App notifications. Here you can see every app that has permission to send notifications. Turn off notifications individually for any app that's using that channel to push ads. If an ad arrives in your notification tray, long-press it and you'll see an option to turn off notifications for that app immediately.

Step 5 — Remove Lock Screen Ads on Android

Identifying Which App Is Serving Lock Screen Ads

The method here overlaps with Step 1. Safe mode will confirm whether a third-party app is responsible. If ads disappear on the lock screen in safe mode, uninstall recently added apps one at a time until the source is found.

Disabling Lock Screen Ads in Device Settings

Some manufacturer skins — particularly on budget Android devices — include lock screen content features that show ads. On Samsung devices, go to Settings > Lock screen and check for any "content" or "information" toggles that may be pulling in ad content. Turning these off removes manufacturer-served lock screen material.

Step 6 — Turn Off Ad Personalisation in Android Settings

Opting Out of Ad Topics

Go to Settings > Google > All services > Privacy & security > Ads privacy > Ad topics. Here you can turn off the feature that tracks topics of interest based on your app usage.

Opting Out of App-Suggested Ads

In the same Ads privacy menu, tap App-suggested ads and turn this off. This stops apps from sharing interest data with Android for cross-app targeting.

Turning Off Ad Measurement

Still in Ads privacy, tap Ad measurement and disable it. This limits the data shared between apps for tracking whether ads led to actions like installs or purchases.

Resetting Your Android Advertising ID

Your Advertising ID is a unique identifier advertisers use to track you across apps. Resetting it breaks that link.

As reported by CNBC, Google has been developing privacy-focused changes to how this identifier works on Android, giving users greater control. To reset it now: go to Settings > Google > All services > Privacy & security > Ads privacy and select Reset advertising ID. Note: this reduces targeting continuity but doesn't stop ads from appearing.

Step 7 — Enable Play Protect to Catch Harmful Apps

Open the Google Play Store, tap your profile icon, then Play Protect > Settings, and make sure Scan apps with Play Protect is on. Play Protect scans installed apps against known harmful software. It won't catch every adware app, but it's a useful baseline check. In practice, teams managing large Android deployments commonly use Play Protect as the first layer in a multi-tool approach to keeping devices clean.

Step 8 — Samsung Galaxy Users: Additional Ad Controls

Disabling the Samsung Customisation Service

Go to Settings > Samsung Account > Privacy > Customisation service and turn it off. This stops Samsung from using your activity data to personalise promotions across Samsung apps. It reduces the relevance of those ads but doesn't eliminate them entirely.

Muting Notification Ads From Samsung Apps

Go to Settings > Notifications and look for Samsung apps (like Samsung Daily or Galaxy Store) that are sending notifications. Turn off notifications for any that are delivering promotional content rather than genuinely useful alerts.

Enabling the Pop-Up Blocker in Samsung Internet

Open Samsung Internet, tap the three-line menu, go to Settings > Sites and downloads, and toggle on Block pop-ups.

Installing an Ad Blocker in Samsung Internet

In Samsung Internet, tap the three-line menu and select Ad blockers. Samsung Internet supports downloadable ad blocker extensions directly within the browser. Look for options with a reasonable number of reviews and a recent update history before downloading.

How to Stop Ads on iPhone (iOS)

Step 1 — Turn Off Personalised Ads in iPhone Settings

Go to Settings > Privacy & Security > Apple Advertising and turn off Personalised Ads.

What Apple's Ad Personalisation Toggle Does and Does Not Do

This setting only affects ads delivered through Apple's own platforms — the App Store, Apple News, and Apple Stocks. It has no effect on ads inside third-party apps like Instagram, free games, or other services. Those apps run their own ad systems.

Step 2 — Block Pop-Ups in Safari

Enabling Safari's Built-In Pop-Up Blocker

Go to Settings > Apps > Safari and make sure Block Pop-ups is turned on. This is off by default on some device setups, so it's worth checking.

Using Content Blockers in Safari

Safari supports content blocker apps that filter ads at the browser level. These are downloaded from the App Store and enabled under Settings > Apps > Safari > Extensions. When evaluating options, look for apps that have been consistently updated, have a clear privacy policy, and don't require excessive permissions.

Step 3 — Revoke App Tracking Permissions

How App Tracking Transparency Works

Apple's App Tracking Transparency (ATT) framework requires apps to ask your permission before tracking you across other apps and websites. If you agreed to tracking in the past and want to revoke it, you can do this per app.

How to Review and Revoke Tracking Per App

Go to Settings > Privacy & Security > Tracking. Turn off Allow Apps to Request to Track to block all future requests, or scroll down to review individual apps and toggle tracking off for specific ones.

Step 4 — Manage App Notification Permissions on iPhone

Go to Settings > Notifications and review which apps have notification access. For any app using notifications as an ad channel, tap it and turn off Allow Notifications. This is particularly relevant for news apps, shopping apps, and free games.

Step 5 — Block Ads in Chrome on iPhone

Open Chrome on your iPhone, tap the three-dot menu, go to Settings > Content settings > Block pop-ups and turn it on. For notification-based ads from websites, go to Settings > Content settings > Notifications and revoke permissions for any sites you don't recognise.

Step 6 — Reset Your iPhone Advertising Identifier

Go to Settings > Privacy & Security > Tracking and turn off Allow Apps to Request to Track. This makes your advertising identifier unavailable to third-party apps, which significantly limits cross-app tracking.

What About Ads on YouTube and Social Media Apps?

This is worth addressing directly because it comes up constantly: ads on YouTube, Instagram, Facebook, TikTok, and similar apps are controlled by those platforms, not by your phone's settings. Adjusting Android or iPhone ad settings will not affect them.

The realistic options are limited. Subscribe to the platform's paid ad-free tier (YouTube Premium, for example), or use a browser-based version of the service with a content blocker active instead of the native app. The browser route works inconsistently and isn't always practical, but it's the only free workaround for platform-controlled ads.

Third-Party Ad Blocker Apps — What to Know Before You Download

Types of Ad Blockers Available for Mobile

Browser-Based Ad Blockers

These work only within a specific browser. On iPhone, Safari content blockers are the most common form. On Android, some browsers like Brave have ad blocking built in. These are the lowest-risk option because they're sandboxed to one app.

DNS-Based Ad Blockers

DNS-based blockers work at the network level, filtering ad requests before they load. They can block ads across all apps, not just a browser. They require more setup and some technical comfort.

VPN-Style Ad Blockers — What They Do and What They Don't

Some apps market themselves as "VPN ad blockers." These route your traffic through their servers to filter ads. They can be effective, but routing all your traffic through a third-party server carries privacy trade-offs. Scrutinise the privacy policy before using one.

What to Look For in a Trustworthy Ad Blocker

Look for apps that are regularly updated, have a published and readable privacy policy, don't request unnecessary device permissions, and have a substantial review history. A newly published ad blocker with few reviews and broad permissions is a risk. In practice, well-established browser-based options carry the lowest risk for most users.

When Persistent Ads May Indicate a Bigger Problem

Signs an App May Be Adware Rather Than Just Ad-Supported

The distinction matters. A legitimate ad-supported app shows ads within its own interface. Adware on Android phones shows ads outside of its interface — on your home screen, in your notification tray, over other apps, or on your lock screen. It may also drain battery faster than expected or cause your phone to run unusually hot.

What to Do If You Suspect Adware or Malware

Run Play Protect on Android (or check for an equivalent scan on your device). Remove recently installed apps one at a time in safe mode. If the problem persists after removing all recently installed apps, a factory reset — while drastic — is the most reliable resolution.

When to Contact Your Device Manufacturer or Seek Further Support

If you've worked through all of the above and the issue continues, contact your device manufacturer's support channel. On Samsung devices, the Samsung Members app provides a direct route. On iPhone, Apple Support is accessible through the Settings app.

Conclusion

Stopping phone ads completely isn't realistic, but meaningful reduction is. Remove suspicious apps first, adjust your browser and notification settings, opt out of ad personalisation, and add a content blocker if needed. Work through the steps in order — most people find the problem resolves within the first two or three.

Frequently Asked Questions

Can I completely stop all ads on my phone?

Not entirely. Ads inside free apps are part of how those apps are funded. You can block browser ads, stop notification ads, and reduce personalised ads — but some ads will remain unless you pay to remove them or switch to paid apps.

Does resetting my Advertising ID stop ads?

Resetting your Advertising ID breaks the tracking link advertisers use to target you across apps. You'll still see ads, but they'll be less targeted. It's a useful privacy step, not an ad blocker.

What is the difference between blocking ads and opting out of personalisation?

Opting out of personalisation makes ads less relevant to you — they keep appearing, just with less targeting. Blocking ads via a browser blocker or DNS tool prevents ads from loading at all within that scope.

Why do ads keep coming back after I block them?

Ad systems update frequently and find new delivery routes. Browser blockers occasionally need updating, and new apps may introduce new ad channels. Regular app audits and keeping your blocker updated help maintain results.

Do paid apps have ads?

Most paid apps don't, but it's not guaranteed. Some apps offer a free tier with ads and a paid tier without — but the paid version occasionally still includes some promotional content. Checking recent reviews before purchasing is the most reliable way to confirm.
