The fastest way to stop ads on an android phone is to uninstall the app causing them, block pop-ups in Chrome, and turn off website notification permissions. Most ad problems on Android trace back to one of these three sources, and all of them can be fixed without rooting your phone or installing anything extra.
Quick Answer: How to Stop Ads on Android Phone
If you are short on time, here is what to do first.
Check your recently installed apps. If pop-up ads started appearing after you downloaded something, that app is almost certainly the source. Go to Settings, tap Apps, find the app, and uninstall it. If the ads are appearing inside Chrome, open Chrome settings, go to Site Settings, and turn off both Pop-ups and Redirects and Ads. If you are getting notification-style ads, go to Chrome, then Site Settings, then Notifications, and turn the whole thing off.
That covers the majority of cases. The table below maps every ad type to the right fix so you can go straight to the method that matches your situation.

Why Are You Getting Ads on Your Android Phone?
Before picking a fix, it helps to understand where the ads are actually coming from. They do not all have the same cause, and using the wrong method will not solve the problem.
Ads Caused by Third-Party Apps
Most pop-up ads on Android come from apps you have installed. Some apps — particularly free utility apps, flashlight tools, cleaner apps, and casual games — run ad scripts in the background even when you are not actively using them.
As reported by TechCrunch, adware apps commonly run on a user's device and silently serve ads in the background without the user's knowledge, generating revenue for developers each time an ad loads or gets clicked. They push ads to your home screen, lock screen, or notification tray. The app itself may look harmless.
In practice, these apps are often ones you downloaded without paying much attention to the permissions they requested. Teams that study mobile ad behaviour commonly report that ad-serving background apps tend to be installed in the same time window as when the ads first appeared. That pattern is useful when you are trying to trace the source.
Ads Caused by Browser and Website Notifications
If you have ever tapped "Allow" on a website's notification prompt, that site can send you ad notifications indefinitely. This is different from a rogue app. The notifications come through Chrome itself, and they look like normal phone alerts. People often assume an app is responsible, but the source is a website they visited once.
Ads from Manufacturer or System-Installed Apps
Some Android phones, particularly Samsung devices, show promotional content inside their own apps like Samsung Pay, Samsung Health, or the default browser. These are not malware. They are opt-in promotional features built into the manufacturer's software. They can be turned off, but the steps are specific to the manufacturer.
Why Turning Off Ad Personalisation Does Not Stop Ads
This is probably the most misunderstood setting on Android. According to Wikipedia's overview of adware, advertising-supported software generates revenue through both ad display and pay-per-click interactions — meaning ads will keep appearing regardless of whether they are personalised or not. When you turn off Google's ad personalisation, you will still see the same number of ads.
What changes is that the ads become less targeted. They will not be based on your app usage or interests anymore, but they will keep appearing. If you are trying to reduce how many ads you see, this setting alone will not do it.

How to Stop Ads on Android Phone: 8 Methods
Method 1: Identify and Uninstall the App Causing Ads
This is the right starting point when ads are appearing outside your browser, on your home screen, or across the phone generally.
Open the Google Play Store. Tap your profile icon, then select Manage Apps and Device. Sort by Last Used. Look for apps you do not recognise or have not used recently. If any were installed around the same time the ads started, start there.
Once you have identified the suspect app, go to Settings, then Apps, then All Apps. Find the app and tap Uninstall.
What to Do If the App Will Not Uninstall
Some rogue apps grant themselves device administrator privileges, which prevents normal uninstallation. To remove these:
- Open Settings and tap Security
- Look for Device Admin Apps (some devices label this under More Security Settings)
- Find the app and disable its admin access
- Go back to Settings, then Apps, and uninstall it normally
Method 2: Use Safe Mode to Find the Problem App
Safe mode starts your Android phone with only the original system apps running. All third-party apps are temporarily disabled. If the ads stop in safe mode, you know a third-party app is responsible.
To enter safe mode on most Android phones, press and hold the power button until the power menu appears. Then press and hold the Power Off option. A prompt to restart in safe mode will appear. Tap OK.
Once in safe mode, observe whether the ads have stopped. If they have, restart normally, then uninstall recently installed apps one at a time until the ads do not return.
Method 3: Block Pop-Up Ads in Google Chrome
This handles ads and pop-ups that appear while browsing.
- Open Chrome and tap the three-dot menu in the top right
- Go to Settings, then scroll to Site Settings
- Tap Pop-ups and Redirects and make sure it is turned off
- Go back to Site Settings and tap Ads, then turn that off too
This stops Chrome from loading intrusive ads and prevents pop-up windows from opening automatically. Most browser-based ad problems on Android are resolved here.
Method 4: Stop Website Push Notification Ads
If ads are arriving as notifications rather than inside a browser window, a website has permission to send them.
- Open Chrome and tap the three-dot menu
- Go to Settings, then Site Settings, then Notifications
- Toggle Notifications off to block all websites from sending them
If you only want to remove specific sites rather than block all notifications:
- Scroll down in the Notifications section to see the list of allowed sites
- Tap each site you want to remove and toggle its permission off
Method 5: Stop Ads on Your Android Home Screen and Lock Screen
Ads appearing here are almost always from a rogue app. The fastest way to identify which one is to long-press the ad notification when it appears. On most Android versions, this will show the name of the app that sent it.
Once you know the app name, go to Settings, then Apps, find the app, and uninstall it. If you cannot catch the notification in time, use the Play Store's Last Used sort method described in Method 1 to narrow it down.
Method 6: Turn Off Samsung-Specific Ads (Samsung Devices Only)
Samsung phones show personalised promotions inside their own apps unless you opt out.
- Open Settings and tap Samsung Account
- Go to Privacy, then Customisation Service
- Turn off the Customisation Service toggle
To stop ad notifications from Samsung apps specifically:
- Go to Settings, then Notifications
- Find any Samsung app sending promotional notifications
- Toggle notifications off for that app
Samsung Internet users can also enable a third-party ad blocker from within the browser. Open Samsung Internet, tap the menu icon, go to Settings, then Ad Blockers, and download one from the list.
Method 7: Turn Off Google Ad Personalisation
This does not stop ads, but it does remove the targeting layer. If privacy is your concern rather than ad volume, this is the relevant setting.
- Open Settings and tap Google
- Tap All Services
- Under Privacy and Security, tap Ads Privacy
- Turn off Ad Topics, App-Suggested Ads, and Ad Measurement
Each of these controls a different part of how Google builds an ad profile from your app activity. Turning all three off means ads shown to you are no longer based on your usage patterns.
Method 8: Enable Play Protect and Use Private DNS
Play Protect scans installed apps for malicious behaviour, including apps that serve intrusive ads without your knowledge.
- Open the Google Play Store
- Tap your profile icon, then Play Protect
- Tap the settings icon and make sure Scan Apps with Play Protect is on
Private DNS routes your internet traffic through a filtering server that blocks ad requests before they reach your phone. This works at the network level and covers all apps, not just browsers.
- Open Settings and tap Network and Internet
- Tap Private DNS
- Select Private DNS Provider Hostname
- Enter a filtering hostname such as dns.adguard.com
This is one of the broader methods available without rooting. It blocks ads in apps, browsers, and background processes simultaneously. The trade-off is that it depends on a third-party DNS provider, so it requires a degree of trust in that service.
Ads Inside Apps: What You Can and Cannot Control
Ads in Free Apps Like Games and Utilities
If you are seeing ads inside a free app you downloaded intentionally, those ads are placed there by the developer as part of their revenue model. No Android system setting removes them. Your options are to upgrade to a paid or premium version of the app if one exists, find an alternative app that is ad-free, or use a Private DNS filter as described in Method 8.
The Difference Between Ads You Can Stop and Ads You Cannot
This distinction is worth being clear about. Ads caused by rogue background apps, browser permissions, and notification settings can be fully stopped with the methods above. Ads served inside legitimate free apps by their developers cannot be removed through Android settings. They are a condition of using those apps for free.
What's often overlooked is that people sometimes apply the wrong fix because they do not separate these two categories. Adjusting Chrome settings will not stop ads inside a game. Uninstalling apps will not stop ads in a browser if the browser settings have not been addressed.
Quick-Reference Checklist: Stop Android Ads in Under 10 Minutes
Run through this list in order if you are not sure where to start.
- [ ] Uninstall any recently installed or unfamiliar apps
- [ ] Use safe mode to confirm whether a third-party app is the source
- [ ] Block Chrome pop-ups via Site Settings
- [ ] Revoke website notification permissions in Chrome
- [ ] Disable Google Ad Topics and App-Suggested Ads
- [ ] Enable Play Protect scan

Conclusion
To stop ads on an android phone, start by removing suspicious apps, then address browser and notification settings. For broader coverage, Private DNS and Play Protect add a useful extra layer. Most ad problems are resolved within the first three methods above.
Frequently Asked Questions
Can I completely stop all ads on my Android phone?
Not entirely. You can stop ads from rogue apps, browser pop-ups, and notification permissions. Ads inside free apps placed there by their developers cannot be removed through Android settings without upgrading to a paid version or using a DNS-based filter.
Does turning off ad personalisation stop ads on Android?
No. Turning off Google ad personalisation changes which ads you see, not how many. Ads will still appear. The personalisation setting only removes the targeting layer based on your app usage and interests.
How do I stop ads on my Android home screen?
Long-press the ad notification when it appears to see which app sent it, then uninstall that app. If you miss it, check your recently used apps in the Play Store and uninstall anything unfamiliar installed around the time the ads started.
Why do I still get pop-up ads after uninstalling apps?
If ads continue after uninstalling, check Chrome's site settings for pop-ups and redirects, and revoke any website notification permissions. Two separate sources can produce ads at the same time, and removing one does not automatically fix the other.
Do I need to root my Android phone to block ads?
No. All the methods above work on a standard, unrooted Android phone. Private DNS offers broad coverage without rooting. Rooting unlocks deeper system-level ad blocking but is not necessary for most users and carries its own risks.
