If you’re searching How to stop pop up ads on Android phone, the fastest solution is to uninstall the recently installed app causing the ads, remove “display over other apps” permission, block pop-ups in your browser settings, and run Google Play Protect to scan for malware. Most pop-up ads on Android start after installing a new free app that contains intrusive adware.
Pop-up ads are not just annoying, they are disruptive, intrusive, and sometimes risky. If ads suddenly start appearing on your home screen, lock screen, or when opening apps, it usually means something changed after installing a new app. In many cases, a third-party app is responsible.
This guide will walk you through identifying the cause, removing unwanted pop-up ads, improving mobile security, and preventing it from happening again.
Why Are Pop-Up Ads Suddenly Appearing on Your Android Phone?
Pop-up ads appear on Android because an installed app has permission to display ads across your device or because your browser allowed intrusive notification access.
Here are the most common causes explained clearly:
- A recently installed free app includes aggressive advertising software that pushes pop-up ads beyond the app itself.
- An app requested “display over other apps” permission, allowing it to show pop-ups on Android across other apps.
- Your browser such as Google Chrome or Firefox allowed a suspicious website to send push notifications.
- Malware or adware was installed unknowingly.
- You clicked on a malicious notification or fake alert.
If ads are appearing on your Android device outside the app you’re using, that is not normal behavior.
How Do I Identify Which App Is Causing Pop-Up Ads?
To identify the source of pop-up ads, check recently installed apps and review special permissions like “display over other apps.”
Start by going to:
Settings → Apps → Installed Apps
Sort by “Last Installed”
Look for:
- Apps installed right before ads started appearing on your Android.
- Apps with no icon on your home screen.
- Generic names like “Flashlight,” “Launcher,” “Battery Saver,” or “Cleaner.”
- Apps with poor ratings in the Google Play Store.
Adware often hides inside harmless-looking apps.
How Do I Know If the Ads Are Coming From an App or Browser?
If pop-up ads appear even when you’re not using a browser, they are coming from an installed app.
Here’s how to tell the difference:
If It’s a Browser Issue
- Ads appear only when you browse the web.
- Ads open in Google Chrome or Firefox.
- Notifications from unknown websites appear at the top of the screen.
If It’s an App Issue
- Ads appear on your home screen.
- Ads pop up when unlocking your Android phone.
- Ads show while opening unrelated apps.
- Ads keep popping randomly.
Understanding the source is the first step to solving the problem correctly.
Check Display Over Other Apps Permission
Apps with “display over other apps” permission can show pop-up ads on Android over everything.
Go to:
Settings → Apps → Special App Access → Display over other apps
If an unfamiliar app has this permission enabled:
- Tap it.
- Disable the toggle immediately.
This one setting is responsible for many intrusive ads across apps and browsers.
Install a Trusted Ad Blocker
A reliable ad blocker can help block intrusive ads across apps and browsers.
Important:
- Install only from Google Play Store.
- Avoid third-party download websites.
- Read reviews carefully.
A built-in ad blocker inside browsers like Chrome and Firefox helps block pop-ups on Android.
How to Stop Pop Up Ads on Android Phone Step-by-Step
To stop pop-up ads on Android phone, remove suspicious apps, disable notification permissions, enable pop-up blocking in browser settings, and scan your Android device for malware.
Follow these steps carefully.
Step 1: Identify and Remove the Recently Installed App
The most effective way to stop pop-up ads on Android phone is to uninstall the app that triggered the problem.
Start by going to:
Settings → Apps → See All Apps
Sort by “Last Installed”
Look for:
- Apps installed just before ads started appearing on your Android device
- Apps with generic names
- Apps you don’t remember installing
- Apps without a visible home screen icon
Tap the suspicious app and select Uninstall.
If uninstall is greyed out, the app may have device administrator access.
In that case:
Settings → Security → Device Admin Apps
Disable admin permission
Then uninstall
Removing the source app stops most pop-up ads instantly.
Step 2: Check “Display Over Other Apps” Permission
This setting is one of the biggest reasons pop-up ads appear across apps.
Apps with this permission can show ads on top of everything.
To check:
Settings → Apps → Special App Access → Display over other apps
Carefully review which apps have this permission enabled.
If you see an unfamiliar app:
- Tap it
- Turn off permission immediately
Many intrusive ads come from apps misusing this feature.
Step 3: Remove Suspicious Browser Notification Permissions
Sometimes pop-ups on Android come from notification permissions granted accidentally.
If using Google Chrome:
Open Chrome → Three dots → Settings → Notifications
Under “Allowed,” review websites carefully.
If you see unknown or suspicious domains:
- Tap the website
- Select Block or Remove
This stops unwanted pop-up ads from appearing as notifications.
Step 4: Enable Built-In Pop-Up Blocking in Chrome and Firefox
Modern browsers include built-in pop-up blockers.
In Google Chrome:
Settings → Site Settings → Pop-ups and redirects
Turn off pop-ups
Also go to:
Settings → Site Settings → Ads
Enable block intrusive ads
In Firefox:
Settings → Enhanced Tracking Protection
Turn it on
These browser settings significantly reduce malicious ads while you browse the web.
Step 5: Clear Browser Data to Remove Hidden Scripts
Sometimes ad scripts stay in your browser cache.
To clear:
Chrome → Settings → Privacy → Clear browsing data
Select:
- Cookies
- Cached files
Clear the data.
This removes stored scripts that cause ads popping repeatedly.
Step 6: Run Google Play Protect to Detect Malware
Google Play Protect is built into the Google Play Store and scans apps installed on your phone for malicious behavior.
Open:
Google Play Store → Profile icon → Play Protect → Scan
If malicious apps are detected:
Uninstall them immediately.
This step improves mobile security and helps stop malicious ads.
What If Ads Keep Popping After Removing Apps?
If ads keep popping even after uninstalling suspicious apps:
Restart your Android device.
If the problem continues, use Safe Mode.
How to Use Safe Mode to Detect Adware
Safe Mode disables third-party apps temporarily.
To enable Safe Mode:
Press and hold the power button → Tap and hold Power Off → Select Safe Mode.
If pop-up ads disappear in Safe Mode:
The problem is definitely caused by a third-party app.
Exit Safe Mode and uninstall apps one-by-one until ads stop.
Are Pop-Up Ads a Sign of Malware?
Yes, sometimes pop-up ads are caused by malware or adware.
If:
- Ads appear on home screen.
- Ads show without opening any app.
- Ads redirect automatically.
- Fake virus warnings appear.
That likely indicates malicious apps installed on your Android device.
Immediate removal is necessary.
Why Free Apps Often Cause Pop-Ups?
Free apps make money through display ads.
However:
- Legitimate apps show ads inside the app.
- Malicious apps show ads across your device.
- Some hide aggressive advertising frameworks.
Always check app reviews before installing.
How to Prevent Pop-Up Ads in the Future
To prevent pop-up ads on your Android phone:
- Install apps only from Google Play Store.
- Avoid clicking suspicious ads.
- Do not grant unnecessary permissions.
- Keep Android OS updated.

These steps significantly reduce risk.
When Should You Factory Reset Your Android Phone?

Consider it only if:

- Android device performance drops drastically.
Before resetting:
- Back up data.
