Identify Where Your Intrusive Ads Are Coming From
The first step to stop intrusive ads mobile is figuring out where they're coming from. Pop-up ads, notifications, and screen overlays don't all have the same source.
Before you start blocking anything, ask yourself these questions:
Do the ads appear in a specific app or across your whole phone?
Do they pop up when you're browsing the web?
Do they show up on your home screen as notifications?
Your answers tell you exactly what to fix. If ads only appear in one app, that app is the problem.
At PHONEPROBS, we help customers deal with unwanted apps and software issues all the time.
Pro Tip Open your phone's notification history or recent apps list. Scroll through and look for unfamiliar app names. If you see something you don't recognize, that's often your culprit. Tap it to see what it does, you may be able to uninstall it right away.
How to Stop Pop-Up Ads on Android
Android devices are frequent targets for intrusive ads because the system gives apps more freedom than iPhone does. Pop-up ads on Android usually come from your browser, a sketchy app you installed, or a background service running without your knowledge.
Disable Pop-Ups in Chrome and Other Android Browsers
Most pop-up ads on Android happen inside your mobile browser. Chrome, Firefox, Edge, and other browsers all have built-in pop-up blockers. The blockers work, but they're not always turned on by default.
For Chrome:
Open Chrome and tap the three-dot menu in the top right
Select Settings
Tap Site Settings
Find and tap Pop-ups and redirects
Toggle the switch to Block pop-ups
For Firefox:
Open Firefox and tap the three-line menu at the bottom
Go to Settings
Tap Privacy
Scroll to Permissions and find Pop-up blocker
Toggle it on
For Edge:
Open Edge and tap the three-dot menu
Select Settings
Tap Privacy, Search, and Services
Find Pop-up blocker and toggle it on
Once your pop-up blocker is on, most ads that try to force their way onto your screen will be stopped. Some sneaky sites still get through, but the blocker catches the majority.
Watch Out Pop-up blockers don't stop all ads. Some websites use clever code to bypass them. If you still see ads after enabling your blocker, move on to the Private DNS method below, it stops ads at a deeper level.
Use Private DNS to Block Ad Networks
Private DNS is one of the most effective ways to stop intrusive ads mobile on Android. It works by blocking requests to known ad-serving servers before they even reach your phone.
Here's how to set it up:
Open your phone's Settings
Tap Network and Internet
Select Private DNS
Choose a DNS provider. Popular options include:
Adguard DNS (for ad blocking)
NextDNS (customizable filtering)
Cloudflare (1.1.1.1 for families)
Tap Save
After you set Private DNS, ads from known ad networks stop reaching your device.
The tradeoff: some websites may load slower, and a few might not work properly if they rely on ad networks for their business model. It's rare, but it happens.
Key Takeaway Private DNS is the single most powerful tool for stopping ads on Android. It blocks ad networks system-wide, which means you're protected in every app and every browser simultaneously.
How to Block Ads on iPhone
iPhone users have fewer intrusive ads than Android users because Apple controls what apps can do more strictly. But ads still happen. They come from Safari, apps you've installed, or Apple's own services if you haven't turned off personalized ads.
Turn Off Personalized Ads in Settings
Apple shows you ads in the App Store, Apple News, and Stocks. You can't eliminate these ads entirely, but you can stop Apple from targeting them to you based on your behavior.
Here's how:
Open Settings
Tap Privacy
Scroll down and tap Apple Advertising
Toggle off Personalized Ads
This stops Apple from tracking your activity and using it to show you targeted ads. The ads don't disappear, but they become random instead of based on your interests.
You can also manage your ad preferences by going to Settings > Privacy > Apple Advertising > View Ad Targeting.
Manage Safari Pop-Up Settings
Safari, Apple's default browser, has a pop-up blocker built in. It's usually on by default, but it's worth checking.
Open Settings
Scroll down and tap Safari
Look for Block Pop-ups and toggle it on
While you're here, also toggle on Fraudulent Website Warning
You can also manage which websites are allowed to send you notifications:
In Safari Settings, scroll to Notifications
Tap Notification Settings
Find websites that send you ads or unwanted notifications
Tap Edit and remove them
Best For iPhone users who want to reduce targeted ads without installing extra apps. Apple's built-in controls are simple and effective for most people.
Block Pop-Up Ads in Your Mobile Browser
Whether you use Android or iPhone, your browser is one of the biggest sources of pop-up ads. Beyond the built-in pop-up blockers, you can take extra steps to reduce what gets through.
Enable Pop-Up Blockers Across Browsers
We covered the major browsers above, but here's a quick recap of what to check:
Chrome: Settings > Site Settings > Pop-ups and redirects (Block)
Firefox: Settings > Privacy > Permissions > Pop-up blocker (On)
Edge: Settings > Privacy, Search, and Services > Pop-up blocker (On)
Make sure you've enabled the blocker in every browser you use. If you switch between Chrome and Firefox, for example, you need to turn on the blocker in both.
Some browsers also let you block ads entirely, not just pop-ups. Firefox and Chrome both have extensions (on desktop) that block ads, but mobile versions have limits. On mobile, your best bet is Private DNS on Android or Safari settings on iPhone.
Customize Site Permissions and Notifications
Websites can ask your permission to send you notifications. Many use this feature to send you ads disguised as notifications. You can manage this in your browser settings.
On Android Chrome:
Tap the three-dot menu > Settings
Go to Site Settings
Tap Notifications
Review the list of sites allowed to send notifications
Toggle off any you don't recognize or don't want
On iPhone Safari:
Go to Settings > Safari
Tap Notification Settings
Review websites that can send notifications
Tap Edit and remove unwanted sites
This stops websites from spamming you with notifications that look like ads. It's one of the most effective ways to reduce interruptions from your browser.
Pro Tip Check your notification settings once a month. Websites often request notification permission when you first visit them, and you might not remember saying yes. A quick review keeps unwanted notifications from piling up.
Stop Unwanted App Notifications and Screen Overlays
Some apps send notifications that look like ads. Others display screen overlays that cover your content. These are harder to stop because they come from apps you've already installed, not from your browser.
Find and Remove Suspicious Apps
The fastest way to stop unwanted ads is to delete the app causing them. But first you need to find it.
On Android:
Open Settings
Tap Apps (or Application Manager)
Scroll through your installed apps and look for ones you don't recognize
If you find a suspicious app, tap it and select Uninstall
If you can't uninstall it (it says "Uninstall" is grayed out), it's a system app, leave it alone
On iPhone:
Go to Settings > General > iPhone Storage
Look at the list of apps and their size
Apps that take up a lot of space but you don't use might be culprits
Tap an app and select Offload App or Delete App
Common culprits include apps with vague names, apps you installed months ago and forgot about, and apps that claim to clean your phone or boost performance.
Before you delete anything, check if the app is something you actually use.
Review App Permissions and Disable Overlays
Some apps ask for permissions they don't need. An app that displays ads might ask for permission to draw over other apps (screen overlays) or to send notifications constantly.
On Android:
Open Settings
Tap Apps
Select an app you suspect
Tap Permissions
Review what it's allowed to do, look for Display over other apps, Notification, and Camera
Toggle off any permissions it doesn't need
If you see Display over other apps enabled, toggle it off immediately, that's how apps create overlays
On iPhone:
Go to Settings > Privacy
Review each permission category (Notifications, Camera, Microphone, Photos, etc.)
Check which apps have access
Remove apps that shouldn't need that permission
Pay special attention to Notifications, toggle off apps that send you ads
Disabling permissions doesn't delete the app, but it stops it from doing certain things. If an app still sends ads after you disable its permissions, uninstall it.
Watch Out If an app forces you to give it permissions before you can use it, but you don't need that permission for the app to work, the app is probably ad-heavy. Consider uninstalling it and finding an alternative.
Check for Malware and Adware on Your Device
If you've tried everything above and ads still keep coming, your device might have malware or adware.
Malware and adware usually come from:
Apps you downloaded from third-party app stores (not Google Play or the App Store)
Sketchy websites that trick you into downloading something
Infected email attachments
Signs of malware or adware:
Ads appear constantly, even in apps that don't normally show ads
Your phone is slow or crashes often
How to check:
Google Play Protect (on Android) and Apple's security (on iPhone) scan for known malware automatically. But you can also run a manual check.
On Android:
Open Google Play Store
Tap your profile icon in the top right
Tap Manage apps and device
Go to the Manage tab
Tap Security
Run a security scan
On iPhone:
iPhone doesn't have a built-in malware scanner like Android does.
If the scan finds malware, it will show you the infected app. Uninstall it immediately.
Key Takeaway Malware is rare on modern phones, but it happens. If ads persist after you've disabled permissions and removed suspicious apps, malware could be the cause. A professional scan is worth the time.
When to Seek Professional Help
Most intrusive ads can be stopped with the steps above. But sometimes you need help from someone who knows phones inside and out.

You've tried all the steps above and ads still appear constantly
Your phone is slow, crashes, or behaves strangely
You can't remove an app that's stuck on your device
PHONEPROBS can help you diagnose the problem and remove unwanted apps or malware. We can also check your phone for other issues that might be causing ads or performance problems. Stop by for a quick evaluation, and we'll let you know exactly what's going on and how to fix it.
Frequently Asked Questions
How can I tell which app is causing pop-up ads on my phone?
Start by noting when ads appear. If they happen when you're not using any app, the ads may come from your browser or notifications. If they appear while using a specific app, uninstall it temporarily to confirm. Check your installed apps for unfamiliar ones with generic names. Go to Settings > Apps (Android) or Settings > General > iPhone Storage (iPhone), sort by size or date, and look for apps you don't recognize. Suspicious apps often have vague names or poor reviews.
What's the difference between blocking ads and using a Private DNS?
Browser pop-up blockers stop ads within websites you visit. Private DNS blocks ad networks at the device level before ads load, protecting all apps and browsers. Private DNS is more comprehensive but may slow your connection slightly. Browser settings are easier to adjust but only work in that specific browser. For maximum protection, use both: enable your browser's pop-up blocker and set up Private DNS through your phone's network settings.
Will ad blockers slow down my phone or drain my battery?
Most browser pop-up blockers have minimal impact on performance. Private DNS may cause a slight slowdown since it filters traffic at the network level, but most users don't notice it. Ad blockers actually save battery by preventing ads from loading and using data. If you experience slowness after enabling an ad blocker, disable it for a few days to confirm it's the cause, then try a different method.
Can I stop ads from appearing as push notifications?
Yes. On Android, go to Settings > Apps > Permissions > Notification, then deny notification access to apps you don't trust. On iPhone, go to Settings > Notifications and turn off notifications for suspicious apps. You can also disable notifications for specific websites in your browser settings. If ads keep appearing after disabling notifications, the app may be malware and should be uninstalled. Check your installed apps for ones you don't remember downloading.
Intrusive ads are frustrating, but they're almost always fixable. Start by identifying the source, browser, app, or notification, then use the right tool for that source. Private DNS on Android and Safari settings on iPhone handle most cases. If ads persist after you've tried everything, PHONEPROBS can run a professional scan and remove any stubborn apps or malware.
