How to Stop Ads on My Phone — Fixes for Android and iPhone

Ads on a phone come from several different places — your browser, downloaded apps, notification permissions, and even your phone's own manufacturer. Which fix works depends entirely on where the ad is appearing. This guide walks through each type with exact steps for both Android and iPhone.

Quick Answer — How to Stop Ads on My Phone Right Now

If you want the short version:

Ads in your browser → block pop-ups in Chrome or Safari settings
Ads as notifications → revoke notification permission for that site or app
Ads on your home or lock screen → find and remove the app sending them
Personalised ads across apps → turn off ad privacy settings on Android or iOS
Ads inside Samsung apps → disable the Samsung customisation service

Not sure which type you're dealing with? The triage table below will point you to the right section.

Before jumping to fixes, it helps to identify where the ad is actually appearing. The cause — and therefore the fix — is different for each scenario.

Where the ad appears	Most likely cause	Jump to
Inside Chrome, Safari, or Samsung Internet	Browser settings or site permission	Browser Ads section
As a phone notification	Website push permission or app notification	Notification Ads section
On your home screen or lock screen	Third-party downloaded app	Home/Lock Screen Ads section
Inside an app you're actively using	In-app advertising model	In-App Ads section
In a Samsung stock app	Samsung first-party promotions	Samsung Ads section
Everywhere, with no clear source	Possible adware or malware	Malware vs Ad-App section

Why Are There Ads on Your Phone?

For an ad to appear on your screen — especially outside an app — something on your device has to have permission to put it there. That's the common thread across every ad type.

Free apps are almost always funded by advertising. The developer makes money when ads are shown; more impressions means more revenue. That's a straightforward arrangement, and most in-app ads fall squarely into it.

What trips people up is when ads appear outside the app — on the home screen, in the notification tray, or on the lock screen. In those cases, the app has either been granted notification access or is running a background service that overlays content. It isn't the phone generating the ad — it's an app you installed (or one that came pre-installed) exercising permissions you may not have consciously approved.

Browser ads work differently again: they're served by websites or scripts running on pages you visit, not by anything installed on the device.

And then there are personalised ads — a layer on top of all of this, where your browsing and app-use data is used to decide which ad you see, not whether you see one at all. Turning off personalisation changes the relevance of ads, not their volume. That distinction matters, and most sources gloss over it.

How to Stop Ads in Your Browser

Browser pop-ups are among the easiest ad types to deal with because the controls are built in.

Google Chrome (Android and iPhone)

Open Chrome and tap the three-dot menu (top right)
Go to Settings → Site Settings → Pop-ups and redirects
Toggle this off
Go back to Site Settings → Ads
Toggle Ads off as well

Chrome's built-in ad filter blocks ads on sites that violate certain standards — mostly aggressive interstitials and auto-playing video ads. It won't catch everything, but it handles the most disruptive formats.

In practice, most people find that blocking pop-ups and redirects in Chrome removes the majority of unwanted browser interruptions immediately.

Safari (iPhone)

Open Settings on your iPhone
Scroll down and tap Safari
Under the General section, toggle Block Pop-ups on
For more coverage, go to Content Blockers and enable any installed content blocker app

Safari's native pop-up blocker is on by default for most users — if you're still seeing pop-ups, check whether it got turned off.

Samsung Internet (Galaxy Phones)

Open Samsung Internet and tap the three-line menu
Go to Settings → Sites and downloads
Toggle Block pop-ups on
Return to the main menu and tap Ad blockers
Download one of the listed ad blockers from the page

Samsung Internet supports third-party ad blocker extensions natively — it's one of the more capable built-in browser options for this purpose.

How to Stop Ad Notifications on Your Phone

Notification ads are distinct from other types. At some point, you (or an app acting on your behalf) granted a website or app permission to send notifications. That permission is what's delivering the ad — and revoking it stops them entirely.

Android — Revoke a Website's Notification Permission in Chrome

Open Chrome
Navigate to the site you want to block
Tap the lock icon (or info icon) in the address bar
Tap Permissions → Notifications
Toggle Show notifications off

To block all website notifications at once:

Open Chrome → Settings → Site Settings → Notifications
Toggle Sites can ask to send notifications off

iPhone — Revoke App Notification Permissions

Open Settings
Tap Notifications
Scroll to the app sending the ads
Tap it and toggle Allow Notifications off

If you're not sure which app sent a notification, long-press the notification when it arrives — on both Android and iPhone this reveals the source app, and gives you a shortcut to turn off that app's notifications directly.

How to Find and Remove Apps Showing Ads on Your Home or Lock Screen

This is the scenario that frustrates people most, because the ad appears when no app is obviously open. Something is running in the background.

How to Identify Which App Is Responsible

Android — Play Store "Last Used" list:

Open the Google Play Store
Tap your profile icon → Manage apps & device → Manage
Sort by Last used

Any app that was active just before an ad appeared is a suspect. If you see an app in that list that you haven't consciously opened recently, that's worth investigating first.

Android — Safe Mode:

Safe mode starts your phone with only the manufacturer's pre-installed apps running. If ads disappear in safe mode, a downloaded app is definitively the cause.

Press and hold the power button
Long-press Power off on screen until the safe mode prompt appears
Tap OK — the phone restarts with "Safe mode" shown at the bottom
Observe whether ads still appear

If they stop, the culprit is a third-party app. Reboot normally, then uninstall recently installed apps one at a time, restarting after each removal, until the ads stop.

iPhone — Screen Time:

Go to Settings → Screen Time → See All Activity
Look for apps with unusually high background activity that you don't recognise using

How to Uninstall the Responsible App

Android: Long-press the app icon → tap Uninstall, or go to Settings → Apps, find the app, and tap Uninstall.

iPhone: Long-press the app icon → tap Remove App → Delete App.

What to Do If the App Is Pre-Installed and Can't Be Uninstalled

Some Android phones — particularly certain budget models — ship with pre-installed apps that show ads and cannot be fully removed.

In that case:

Go to Settings → Apps
Find the app and tap Disable — this stops it from running without removing it
Also go to Permissions within that app's settings and revoke notification and display-over-other-apps permissions

Disabling a pre-installed app doesn't delete it, but it prevents it from running in the background and removes it from your app drawer.

How to Reduce Ads Inside Apps

In-app advertising — banners and interstitials that appear while you're using an app — is the hardest category to block at the system level, because the ad is being served inside the app's own environment.

Three practical options:

Pay for the ad-free version. Most ad-supported apps offer a paid tier that removes ads. If you use the app regularly, this is usually the cleanest solution.
Switch to an alternative. For most app categories, there's at least one free alternative with fewer or no ads.
DNS-level ad blocking. Tools that filter DNS queries can intercept ad requests before they load — across apps and browsers. This approach can meaningfully reduce in-app ads, though it won't catch ads served from the same servers as the app's actual content.

What doesn't work: clearing the app's cache, force-stopping it, or toggling its permissions on and off won't prevent ads from loading when the app is running normally.

How to Turn Off Personalised Ads on Android

Android's ad system uses topics inferred from your app usage and browsing to decide which ads are relevant to you. Apps can also store interest signals with Android, which other apps can then request when choosing what to show you.

Turning this off changes which ads you see, not how many. That's worth being clear about upfront — a lot of people disable personalisation expecting ad volume to drop, and are surprised when it doesn't.

Step-by-Step: Android Ad Privacy Settings

Open Settings
Tap Google → All services
Under Privacy & security, tap Ads → Ads privacy

From here you can manage three things:

Ad topics — the interest categories Android has inferred about you. You can view and delete individual topics, or turn the feature off entirely.
App-suggested ads — signals shared between apps to inform ad choices. Toggle off to stop apps from sharing this data.
Ad measurement — limited data sharing used to measure whether an ad led to an action. Toggle off to opt out.

The Advertising ID

Your Android device has an advertising ID — a resettable identifier that advertisers use to link your behaviour across apps. You can reset it (which breaks the link between past data and future tracking) or delete it entirely (which prevents apps from accessing it at all).

According to Fortune, Google confirmed that when a user opts out, developers will no longer be able to see that user's unique advertising ID — and will receive a string of zeros in its place.

To find it: Settings → Google → All services → Ads → Advertising ID

Deleting the advertising ID is the more thorough option. After deletion, apps that request it receive a string of zeros, which effectively removes you from cross-app tracking.

After Opting Out — What Changes and What Doesn't

Setting changed	What changes	What stays the same
Ad topics off	Ads are no longer targeted to your inferred interests	Total number of ads you see
App-suggested ads off	Apps can't share interest signals	Ads still appear in all apps
Ad measurement off	Your actions aren't tied back to ad exposure	Ad delivery is unaffected
Advertising ID deleted	Cross-app tracking link broken	Contextual ads (based on content, not you) continue

How to Turn Off Personalised Ads on iPhone

Apple's personalised ad system covers ads within Apple's own apps — the App Store, Apple News, and Stocks. It does not govern ads inside third-party apps, which are managed by those apps and their own ad networks.

Step-by-Step

Open Settings
Go to Privacy & Security → Apple Advertising
Toggle Personalised Ads off

This stops Apple from using your data to target ads within its own apps. Third-party app ads are unaffected by this setting.

For a broader reduction in cross-app tracking by third parties:

Go to Settings → Privacy & Security → Tracking
Toggle Allow Apps to Request to Track off

With this off, apps cannot ask for permission to track you across other companies' apps and websites — and any that previously had permission lose it.

How to Stop Ads in Samsung Apps

Samsung's own apps — including the Galaxy Store, Samsung Pay, and the default keyboard on some models — can show promotional content if the customisation service is enabled. These are first-party promotions, separate from any third-party app ads.

Turn Off Samsung's Customisation Service

Open Settings
Tap Samsung Account
Go to Privacy → Customisation service
Toggle it off

This reduces personalised promotions in Samsung's apps. It won't stop ads from third-party apps you've downloaded, and it won't remove all promotional content from Samsung's apps — just the personalised portion.

Mute Ad Notifications from Samsung Apps

Go to Settings → Notifications
Find the Samsung app in question
Toggle notifications off for that app

Samsung's ads are opt-in by default at account setup — if you're seeing them now, the customisation service was likely enabled during initial phone setup without being noticed.

Is It Malware or Just an Ad-Supported App? How to Tell

Most ads on phones are annoying, but normal. A smaller number indicate something more serious. Here's how to tell the difference.

Symptom	Ad-supported app (normal)	Possible malware
Ads appear only when a specific app is open	✓
Ads appear when no app is visibly open		✓
Browser homepage changed without your action		✓
New apps appeared that you didn't install		✓
Battery draining unusually fast with no obvious cause		✓
Ads match content you recently browsed	✓
Ads include fake virus warnings or urgent alerts		✓
Ads disappear entirely in safe mode		✓ (strong indicator)

As reported by TechCrunch, security researchers have repeatedly uncovered adware-laden apps on Google Play — including cases where millions of users were affected by apps running hidden background ads without any obvious sign in normal use. Malicious apps that do nothing suspicious on the surface are a recurring pattern, which is precisely why the safe mode test is useful.

If symptoms point to malware:

Boot into safe mode (Android) to confirm a third-party app is the cause
Uninstall recently installed apps one by one, restarting and testing after each
Enable Play Protect on Android: open the Play Store → profile icon → Play Protect → Scan
On iPhone, check Settings → General → VPN & Device Management for unfamiliar profiles — delete any you don't recognise

If the safe mode test shows ads disappearing, you're looking at an installed app, not a system-level infection. Work through recent installs methodically rather than panic-deleting everything at once.

Can You Stop All Ads on Your Phone?

Honestly? Not completely. But you can get close for specific ad types.

Fix applied	What it stops	What it does not stop
Block browser pop-ups	Browser redirects and pop-ups	In-app ads, push notifications, screen overlays
Revoke notification permissions	Website push notification ads	Pop-ups, in-app ads, screen overlays
Uninstall the ad-serving app	Home/lock screen overlays from that app	Ads in other apps or browsers
Opt out of personalisation (Android/iOS)	Targeted ads — partially	Total ad volume
Browser-level ad blocker	Most browser ads	In-app ads, push notifications
DNS-level ad blocking	Ads across many apps and browsers	Ads served from same domain as app content
Disable Samsung customisation	Samsung first-party promotions	Third-party app ads on the same device

One thing worth knowing about VPNs marketed as ad blockers: they typically filter DNS requests in the same way a dedicated DNS blocker does. They can reduce ads meaningfully, but they carry the same limitations — ads embedded in app content won't be caught, and their effectiveness varies by app and ad network.

There's also a trade-off that doesn't often get mentioned. Ads fund free apps. Removing them entirely — especially through DNS blocking — can break app functionality in some cases, since ad SDKs and content delivery sometimes share infrastructure. That's not a reason to live with intrusive ads, but it's worth knowing the fix isn't always clean.

Conclusion

To stop ads on your phone, match the fix to where the ad appears — browser, notification, home screen, or inside an app. Personalisation settings reduce targeting, not volume. Complete ad removal isn't possible, but the right combination of steps can eliminate most of what's bothering you.

Frequently Asked Questions

Will turning off personalised ads reduce how many ads I see?

No. Turning off personalisation changes which ads appear, not how many. Ad volume is set by the apps and sites you use, not by your personalisation preferences. You'll still see the same number of ads — they'll just be less targeted to your interests.

Are pop-up ads on my phone a sign of a virus?

Not always. Most pop-up ads come from ad-supported apps or browser sites — that's normal, if annoying. Malware is more likely if ads appear when no app is open, your browser homepage has changed, or apps you didn't install have appeared on your device.

Why do ads keep appearing after I delete an app?

If you've removed the app that was causing ads and they persist, a different app is likely responsible. Use Android's safe mode or the Play Store "last used" list to identify which app is still active in the background.

Can I block ads on my phone without installing extra apps?

Yes, for browser ads — Chrome, Safari, and Samsung Internet all have built-in pop-up and ad controls. For notifications and personalised ads, the built-in phone settings cover it. In-app ads cannot be reliably blocked without a third-party tool or DNS filter.

What is the Android advertising ID and should I delete it?

It's a device-level identifier that lets advertisers track your behaviour across different apps. Resetting it breaks the link to past data. Deleting it entirely prevents apps from using it at all, which is the more thorough option if you want to reduce cross-app tracking.
