How to Get Rid of Ads on My Phone (Android and iPhone Guide)

Ads on a phone usually trace back to one of three sources: a specific app, the browser, or the phone's own system settings.

Figuring out how to get rid of ads on my phone starts with identifying which of the three is responsible, then fixing that source directly.

Why Ads Show Up on Your Phone in the First Place

Most ads come from free apps that display them to generate revenue for the developer, and according to Wikipedia, offering software free of charge while relying on advertising to recoup costs is a long-standing model among app developers.

That's the trade-off of not paying for the app itself. Some ads instead come from the browser, triggered by a site that gained notification permission at some point.

And on certain phones, the manufacturer builds promotional content directly into the operating system, on the lock screen or inside a pre-installed app.

In practice, most people dealing with unwanted ads are facing one of these three, not all of them at once.

Teams that troubleshoot this kind of issue commonly report that narrowing down the source first saves a lot of wasted effort later.

How to Get Rid of Ads on My Phone by Finding the Source First

Before changing any settings, it helps to know what's actually causing the ads.

How to Get Rid of Ads on My Phone Caused by a Specific App

Ads tied to a specific app usually only show up while that app is running or shortly after. If a pop-up appears out of nowhere, check which app was last active.

On Android, this is visible in the Play Store under installed apps sorted by last used. On iPhone, the App Switcher shows recently used apps.

Use Safe Mode to Narrow It Down (Android)

Restarting an Android phone in Safe Mode temporarily disables third-party apps. If the ads stop in Safe Mode, one of the recently installed apps is the cause.

Removing apps one at a time, then restarting normally after each, is slower but reliable for confirming which one it is.

Handle Apps That Resist Uninstalling

Some apps use admin-level permissions to block removal. On Android, this needs to be turned off first, under Settings, then Security, then Device Admin Apps, before the app can be deleted.

Removing Ads on Android

Once the source is identified, the fix usually falls into one of these categories.

Uninstall the app. Go to Settings, then Apps, find the app, and uninstall it.

Block pop-ups in Chrome. Open Chrome, tap the three-dot menu, go to Settings, then Site

Settings, and turn off both Pop-ups and Redirects and Ads.

Turn off notification-based ads. In Chrome's Site Settings, tap Notifications and turn off permissions for sites sending unwanted alerts.

Turn off personalized or system ads. Phone manufacturers sometimes run their own ad system.

On Samsung devices, for example, this setting sits under Settings, then Samsung Account, then Privacy, then Customisation Service.

Removing Ads on iPhone

iPhone ads generally come from the same three sources, just with different settings paths.

Uninstall the app. Press and hold the app icon, then choose Remove App.

Turn off pop-ups and notifications in Safari. Go to Settings, then Safari, and turn off Pop-ups.

For site-specific notifications, go to Settings, then Notifications, find the site or app, and turn its alerts off.

Turn off personalized advertising. Go to Settings, then Privacy & Security, then Apple

Advertising, and turn off Personalized Ads. This reduces how targeted the ads are, though it doesn't remove ads from every app.

Blocking Ads Across the Whole Phone

Some ads keep reappearing no matter what's uninstalled, usually because they're built into a browser or an ad network rather than tied to one app. Two broader options exist for this.

Method	What It Covers	Setup Effort	Typical Cost
Browser content blocker	Ads inside one browser app	Low	Often free
DNS-based ad blocker	Ads across all apps and browsers on the device	Moderate	Free to low-cost
Uninstalling the source app	Ads from that one app only	Low	Free

A DNS-based blocker reroutes ad-serving domains at the network level, so it works across apps rather than just one browser. It's a broader fix, but it also filters more of the phone's traffic, so it's worth checking a DNS provider's reputation before setting one up rather than picking the first result in an app store.

When Ads Point to Something More Serious

Occasionally, ads that appear constantly, across every app, even with no browser open, point to something beyond normal app behavior.

Signs That Suggest Malware

Full-screen ads with no app open, a phone that suddenly runs hot or drains battery fast, or new apps appearing that were never installed are signs worth taking seriously.

As reported by TechCrunch, some malicious Android apps have been found running in the background and serving ads after every reboot specifically to generate revenue without the user's knowledge.

When a Factory Reset Is Worth Considering

If uninstalling suspected apps doesn't stop the ads and the signs above are present, a factory reset is usually the most reliable remaining option. It's a last step, not a first one, since it erases the device.

Conclusion

Getting rid of ads on a phone comes down to finding the source, whether that's an app, a browser setting, or a system feature, and adjusting it directly. Broader blocking helps when ads persist across multiple apps.

FAQ

Can I get rid of ads on my phone completely?

Not always. Free apps often rely on ads to stay free, so some ads may return unless the app is removed or replaced with a paid version.

Why do ads keep coming back after I close them?

This usually means the source app is still installed, or a website still has notification permission. Removing the app or revoking the permission stops the recurrence.

Is it safe to use an ad-blocker app?

Most reputable ones are, but it's worth checking reviews and permissions before installing one, since some apps marketed as blockers request more access than they need.

Do ad-blocking methods work the same on Android and iPhone?

Not exactly. Android allows more system-level blocking options, while iPhone relies more on Safari settings and content blocker extensions from the App Store.

Will a factory reset remove all ads?

In most cases, yes, since it removes every installed app. It should be used only after simpler fixes haven't worked, since it also erases personal data.
