How to Block Unwanted Ads on Your Android Phone [2026]

You open a news site to read one headline. Before the page loads, a full-screen video ad pops up. You close it. Another ad slides in from the bottom. You tap the wrong close button, because the real one is tiny, and suddenly the Play Store opens for an app you never wanted. If this sounds like your daily phone experience, you are not alone. Indian Android users face some of the heaviest ad clutter in the world, from aggressive app ads to fake "Your phone has a virus" pop-ups on Chrome.

Here is the straight truth. You cannot block every single ad on Android without rooting your phone, and you should not try. But you can block almost all the annoying ones: pop-ups, full-screen video ads, ads on the lock screen, and ads inside Chrome. The steps below are safe, free, and do not need any shady app. I have used them on my parents' phones, and their weekly pop-up complaints have stopped.

First, Work Out What Kind of Ads You Are Seeing

Not all ads are the same, and the fix depends on the type. Take 30 seconds to notice where your ads appear. This saves you from installing the wrong fix.

Ads inside Chrome while you browse are normal web ads. Some sites overdo them, but they are not a sign of infection. Ads on your home screen, lock screen, or while using WhatsApp or the dialer are different. Those usually come from a recently installed app with permission to draw over other apps. Ads that look like system warnings, like "Your phone is infected, tap here to clean", are almost always fake, and tapping them leads to a scam app or payment page.

Ads in free games and apps, like a video ad between game levels, are built into the app itself. You cannot remove those with a browser setting. You either pay for the premium version, switch to a less greedy app, or limit the app's tricks as described below. Once you know which type you have, the right section below will fix it.

Block Pop-Ups and Ads in Chrome

Chrome is where most Indian users meet the worst ads, so start here. Open Chrome on your phone, tap the three dots at the top right, then Settings, then Site settings. First, tap Pop-ups and redirects and turn it off. This alone stops most new tabs that open by themselves when you tap a page. Next, tap Intrusive ads and turn that off too. Chrome will then block ads on sites known for abusive ad behaviour.

Go back to Site settings and tap Notifications. Many users tap Allow by mistake when a site asks "Show notifications?" and then get ad notifications all day. Block every site you do not recognize, and every news or shopping site that spams you. Keep notifications on only for sites you actually want. This one cleanup often cuts daily ad notifications by half.

One more Chrome setting helps a lot. Under Settings, tap Privacy and security, then turn on Safe Browsing if it is off. Safe Browsing warns you before you open a site known for phishing or malware. It will not block normal ads, but it stops fake virus warning pages from tricking you into installing a cleaner app. Samsung Internet users can turn on Block pop-ups under Settings, then Sites and downloads. Firefox users can install the uBlock Origin add-on.

Use a Private DNS to Block Ads Across Apps

This is the most powerful free trick in this guide, and it takes two minutes. Private DNS blocks ad domains before they even load, across many apps and browsers at once. It does not need root, and it does not need a separate app running all the time.

Here is how to set it up. Open Settings, then Network and internet, then Private DNS. On Samsung phones the path is Settings, then Connections, then More connection settings, then Private DNS. Select Private DNS provider hostname, and type dns.adguard-dns.com, then tap Save. AdGuard runs a free public DNS service that blocks known ad and tracking domains. You can also use one.one.one.one for Cloudflare, but that blocks malware, not ads, so AdGuard is the better pick for this job.

What will change? Many banner ads in free apps will show as blank spaces instead of loading, and some video ads will fail to play. If a banking app or video app stops working, switch Private DNS back to Automatic. Banking apps like SBI Yono, Paytm and PhonePe work fine with AdGuard DNS in my experience, but some ad-heavy games may load slower.

One honest warning: Private DNS does not block YouTube ads, because YouTube serves ads from its own domain. It also does not block ads inside Facebook or Instagram feeds, which are part of the app itself. For those, you need the app-level steps below, or you accept them as the price of a free app.

Find and Remove the App Behind Home Screen Ads

If ads appear when you are not even browsing, an app is the culprit. This is common after installing a free photo editor, a battery saver, a file cleaner, or a launcher from outside the Play Store. These apps ask for permission to display over other apps, then abuse it to show full-screen ads.

Finding the app is easier than most people think. The next time a full-screen ad appears, open Settings, then Apps, and look at recently opened apps. The app that just showed the ad will sit near the top. You can also go to Settings, then Apps, then Special app access, then Display over other apps. If a torch app, cleaner app or random game has this permission, turn it off. A torch app has no reason to draw over other apps.

Once you find the suspect, uninstall it. Long-press its icon and tap Uninstall. If the app refuses to uninstall or hides its icon, boot into Safe Mode by holding the power button, then long-pressing Power off until Safe Mode appears. In Safe Mode, third-party apps cannot run ads, so you can uninstall the offender calmly, then restart normally.

If the ads continue even after removing suspicious apps, your phone may have adware hiding deeper. Our guide on how to remove virus from Android phone without antivirus walks through the full cleanup steps, including Safe Mode and a factory reset as a last resort. Do not install a random "ad blocker" app to fix this, because many of those apps are themselves adware in disguise.

Stop Ads on Your Lock Screen and Notifications

Lock screen ads usually come from one of three places: a third-party launcher, a wallpaper app, or a shopping app that changed your lock screen settings. If you recently installed a "HD wallpapers" or "charging animation" app, uninstall it and see if the ads stop.

Second, check notification permissions under Settings, then Notifications, then App notifications. Turn off notifications for shopping apps, games and utility apps that send promotional messages every day. Flipkart, Amazon and Meesho are useful, but you do not need a sale alert from each of them four times a day.

Third, check your brand's own ad settings. On Xiaomi phones, go to Settings, then Passwords and security, then Authorization and revocation, and turn off msa, the system ads service. Also turn off personalized ad recommendations under Privacy, then Ad services. On Samsung phones, go to Settings, then Privacy, then Customization Service, and turn off customized ads. On Realme phones, look under Settings, then Additional settings, then Get recommendations, and turn it off. These settings cut down ads in system apps like the file manager and theme store.

Block Ads in YouTube, Games and Free Apps

Let us be honest about the limits here. YouTube ads cannot be blocked legally on the official YouTube app without YouTube Premium. Tricks like modified YouTube apps from unknown websites carry real risks, including malware and account bans, and I do not recommend them. If YouTube ads bother you daily, YouTube Premium Lite or a shared family plan is the safe option, and it also gives you background play and downloads.

For games and free apps, you have three fair choices. First, check if the app offers a one-time payment to remove ads. Many Indian apps charge ₹49 to ₹199 to remove ads forever, which is cheaper than the data and battery those ads burn over a year. Second, turn on Aeroplane mode before playing an offline game. Without internet, most in-app ads cannot load. Third, switch apps. If a photo editor shows a 30 second video ad before every edit, another free editor probably does the same job with fewer ads.

Ads also drain your battery, because video ads keep your screen and processor busy. If you are fighting both problems, read our guide on how to extend your Android phone battery life. Cutting ad load and background activity together gives you a faster phone that lasts longer between charges.

What Not to Do: Ad Blocker Traps

This section matters, because the Play Store is full of apps that promise to block all ads and then cause bigger problems. Avoid these traps.

Do not install ad blocker apps that ask for VPN permission unless you know and trust the developer. A VPN-based ad blocker routes all your internet traffic through its servers, which means it can see your browsing and logins. If an ad blocker app has few downloads, no website, and spelling mistakes in its description, skip it.

Do not download APK files of "ad-free" versions of paid apps from random websites. These files are a common way to install malware, and Google Play Protect will often flag them. Do not tap "Allow" on every permission prompt either. A flashlight app does not need your contacts, your location and permission to draw over other apps.

Do not pay for an "ad removal" service that contacts you through WhatsApp or a pop-up. Genuine ad removal happens inside the app itself, through the Play Store payment system. Anyone asking you to pay through UPI to a personal number to remove ads is running a scam. If you are unsure about an app, our guide on how to keep your phone safe from hackers covers the warning signs to check first.

My Honest Final Take

Here is what I would tell my own family. Start with Chrome settings and Private DNS today. Those two steps are free, safe, and take less than 10 minutes together, and they remove the majority of the ads most people complain about. Then hunt down the one app behind your home screen ads, if you have them, and uninstall it without mercy.

Do not chase a perfect ad-free phone. YouTube, Instagram and Facebook will still show their own ads, and that is how those free services pay their bills. The goal is not zero ads. The goal is a phone that does not interrupt you, trick you with fake virus warnings, or burn your data and battery on ads you never asked for. With these steps, you will notice the difference the same day.
