You’ve installed one of the best ad blockers we’ve recommended, but still, you keep seeing some ads. That’s not necessarily your ad blocker malfunctioning. Some ads just can’t be blocked, and others need a special workaround that ad blockers alone cannot do. Also, it’s easier to block ads on a browser than it is on your phone or smart TV. Those are closed systems, with more closed apps. That’s just how it is. And even the best ad blockers sometimes hit a wall as some ads slip right past the strongest filters.
We’re here to talk about the reasons why and maybe see if you can do anything about it.
Why Do I Still See Ads Even With an Ad Blocker Installed?
Even the best ad blocker has blind spots. Most ad-blocking extensions are made for web browsers, so they’re better at filtering ads on websites. But ads outside your browser… like inside mobile apps or device interfaces, these ad blockers often fail. In fact, many mobile ads and in-app promotions keep coming in because the blocking methods aren’t universal and don’t work on them.
For example, on iPhones, content blockers only work in Safari, not within other apps. And on all platforms, some ads are delivered in ways that make them indistinguishable from regular content, which we’ll talk more about in a second. As a result, you might still see ads in places like your Facebook app, YouTube app, smart TV menu, or even your email inbox, despite running an ad blocker.
Traditional ad blockers mainly filter out third-party ads on websites. They falter when ads come from the same source as the content you want or when ads are delivered through apps and systems that don’t allow external filtering. Even mobile-wide ad blockers or DNS-based blockers can’t remove every ad.
Why Can’t Ad Blockers Remove Facebook and Instagram Ads?
If you’ve ever tried to get rid of the ads from Facebook, Instagram, or TikTok mobile apps, you probably realized that you can’t. Ad blockers struggle with in-app ads on these apps because of how they serve their ads. Unlike ads on a webpage that come from obvious ad-server domains, Facebook and Instagram load their ads from the same servers that deliver your friends’ posts and photos. In other words, the ads share the same domain and API endpoints as legitimate content. A network-level blocker (like a Pi-hole or private DNS) can’t simply block the “ads” domain, because there is no separate ad domain; it’s all coming from Facebook’s own servers.
Moreover, mobile apps are a locked environment. Browser ad-block extensions can’t hook into a native app to hide elements the way they do on web pages. These social media apps deliberately design their ads to blend in as regular posts (sponsored posts, suggested content), making external filtering nearly impossible. They are essentially first-party ads, delivered by the app’s servers and styled as part of the feed, so traditional ad block filters can’t single them out. Facebook has an entire team dedicated to ad delivery, ensuring that ads render like normal content and even actively obfuscating ad code to thwart ad blockers on the web. On mobile, they don’t even need to obfuscate; the app’s closed nature already locks blockers out.
In practical terms, this means you cannot effectively block ads in the Facebook, Instagram, or TikTok apps with a normal ad blocker. The best you can do is hide specific ads that you don’t like, and fiddle around the settings to limit tracking. But even then, there is always some form of tracking happening with these apps, mainly because they have so much data on you. That’s the price you pay for using a “free” service.
Why Does YouTube Still Show Ads on My Phone and Smart TV?
One of the main reasons a lot of people use ad blockers is because of YouTube. YouTube ads are intrusive, and they keep getting worse every time. And while ad blockers like AdGuard successfully block YouTube ads on desktop browsers, it’s not the same for mobile devices and smart TVs. The official YouTube apps on phones and streaming devices pull both videos and ads from YouTube’s own domain (youtube.com).
DNS blockers can’t outright block youtube.com without also blocking all video content. At the network level, an ad video looks identical to a regular YouTube video stream. There’s no simple way to filter one while allowing the other.
Browser extensions don’t work in the YouTube mobile app, and the app provides no built-in ad-skipping for free users. Smart TV YouTube app faces the same limitations. Samsung reportedly proxies YouTube traffic through its TVs’ servers, which prevents DNS blockers like Pi-hole from identifying and blocking ads without breaking the entire video stream.
This tactic is called server-side ad insertion. It blends ads into the content stream. From the app’s perspective, the ad becomes part of a single continuous video and leaves no separate call for ad blockers to intercept.
Standard ad blockers hit a wall with YouTube on mobile and TV platforms. Some users watch YouTube in mobile web browsers with content blockers (less convenient than the app), install specialized apps, or use browser-based casting. The most straightforward solution remains YouTube Premium, which removes ads across all devices through a paid subscription.
Can I Block Ads on My Smart TV’s Home Screen?
Smart TV platforms like Samsung Tizen, LG webOS, and Roku integrate promotional content directly into their UI. Samsung has clearly stated that you cannot fully disable ads on their smart TVs, and that the promotional content is baked into the system.
Some settings can reduce these ads. On Samsung, you can disable “Interest-Based Ads” in Privacy settings and turn off “Auto-Run Smart Hub.” These steps might stop personalized targeting or occasional pop-ups, but won’t remove static ad slots from the home screen. LG and other manufacturers offer settings to opt out of tailored ads, which may make ads more generic or hide some content suggestions, but the allocated ad space remains.
Network-level DNS blockers can sometimes intercept ad domains used by TV software. Blocking known Samsung ad domains might prevent some promotional content from loading, though users report that aggressive blocking can disable streaming services as manufacturers often intertwine ad requests with core TV functions. And even after blocking ads, you might still be left with empty placeholders that can break immersion even further.
Your best mitigation strategies include searching your TV’s settings for any “suggestions” or “marketing” options to disable, keeping firmware updated, or, in extreme cases, keeping the TV offline and using external streaming devices to bypass the smart interface entirely.
Are Mobile Game Ads Unblockable?
Mobile games, especially free ones, heavily rely on ad revenue. Ad blockers have limited power inside games for several reasons.
Many games fetch ads from online ad networks. On Android, DNS-based blockers or VPN-style ad blockers (AdGuard, Blokada) can block many ad networks. This can prevent ads from loading in games that rely on standard ad servers. However, if a game can’t reach its ad server, it might not give you rewards or could pause, assuming there’s no internet connection.
On iPhones, the situation is tougher. iOS doesn’t allow system-wide ad blocker apps for content; you can only use Safari content blockers. Ads inside iPhone games are largely untouchable unless you configure network-wide DNS blocking via your Wi-Fi router.
Two simple workarounds sometimes help: playing offline (airplane mode prevents ads from loading in single-player games that don’t require internet) and checking the game’s settings for a paid “remove ads” option. Many games offer inexpensive in-app purchases to get rid of these interruptions.
System-wide blockers can remove substantial ad traffic, but blocking game ads might come with side effects like losing reward opportunities or receiving error messages. It’s an ongoing battle between ad-serving games and ad-averse players.
Why Does My Operating System Show Built-In Ads?
Modern operating systems increasingly include advertisements or promotional content. Windows 10/11 displays “suggested apps” in the Start menu and banner ads in File Explorer. Some Android phones (Xiaomi’s MIUI, Samsung’s OneUI) show ads inside system apps or on home screens.
How Do I Disable Windows 10/11 Ads?
Microsoft has introduced recommendations and advertisements throughout Windows. Fortunately, many can be disabled in settings:
In Windows 11, navigate to Settings > Personalization > Start and turn off “Show recommendations for tips, shortcuts, new apps, and more.” Under Settings > Privacy & security > General, disable “Show me suggested content in the Settings app.” These steps significantly reduce built-in advertising.
For lock screen ads, switch from Windows Spotlight to a Picture or Slideshow and turn off “Get fun facts.” Once you’ve disabled these toggles, Windows feels considerably cleaner, and the OS doesn’t re-enable them after updates.
How Do I Remove Ads From Xiaomi and Samsung Phones?
Xiaomi integrates ads aggressively into MIUI. You might see them in the file manager, music player, or settings screens. The company uses ad revenue to keep phone prices low, but there’s no official way to pay to remove all ads entirely.
You can disable most ads through settings. Revoke authorization for the “MSA” (MIUI System Ads) app, toggle off “Personalized ad recommendations” in Privacy settings, and go app-by-app (Security, Browser, Music) to find and disable “recommendations” toggles.
Samsung phones aren’t as ad-heavy, but sometimes push notifications for services or show ads in stock apps like Weather. Samsung usually lets you opt out of marketing when setting up the phone, or via “Receive marketing information” in privacy settings.
Amazon Fire devices come in cheaper “With Special Offers” versions subsidized by lockscreen ads. Amazon lets you pay a fee (typically $10-15) after purchase to permanently remove ads by converting to “Without Special Offers” status. To learn more about that, read How to Remove Ads from Kindle.
How Do These Ads Bypass Ad Blockers?
Ads that successfully bypass blockers share common characteristics. They disguise themselves as regular content. Advertisers use some clever techniques here clever techniques:
First-Party Ad Delivery
Traditional ad blockers block requests to known ad servers, such as doubleclick.net. When ads are served from the same domain you’re visiting (YouTube ads from youtube.com or Facebook ads from facebook.com), ad blockers can’t block the entire domain without breaking everything. Many platforms have shifted to first-party ad delivery specifically to nullify ad blockers.
App Sandboxing and Encryption
Mobile operating systems isolate app data and traffic for security, preventing ad blockers from injecting themselves into app internals. All app traffic is encrypted (HTTPS), so network-level blockers can only see the domain being accessed, not specific request content.
Even if a blocker could identify that a certain URL path serves an ad, encryption prevents it from seeing that information. If the domain matches legitimate content, the blocker is blind. On iOS, Apple’s rules prohibit altering other apps’ traffic, limiting you to Safari filtering only.
Server-Side Ad Insertion
This technique, used heavily in video streaming (Twitch, live TV apps), stitches ads into the content stream on the server side. The client device receives one continuous stream where ads aren’t separate elements to block—they’re literally frames in the video. When ads are injected server-side, clients can’t distinguish between content and advertisement chunks, making blocking impossible.
Frequent Format Changes and Obfuscation
Companies intentionally change ad code or element IDs to outsmart filter lists. If a filter blocks HTML elements with IDs containing “ad_banner,” websites randomize IDs or use names that don’t trigger filters. Some sites use scrambled class names or dynamically generate ad content via scripts, making it hard for blockers to catch without constantly updated rules.
What Can Actually Block These Hard-to-Block Ads?
While no solution is perfect, combining several tools and approaches can significantly reduce even stubborn ads:
Network-Level DNS Blocking
Tools like Pi-hole or AdGuard DNS operate at the network level to block known ad domains across all devices. They can’t eliminate first-party ads on domains like facebook.com or youtube.com, but they obliterate third-party ads and trackers in mobile apps and smart TVs. Pi-hole can stop mobile games from calling ad networks and smart TVs from fetching ad images from manufacturer servers.
VPN-Based Ad Blockers
Apps like AdGuard for Android (a standalone app) or Blokada act as local VPNs on your device to filter traffic. They maintain blocklists and can cut off many in-app ads system-wide. On Android, this works effectively. On iOS, options are more limited due to Apple’s restrictions, but some apps use DNS protection approaches to filter content.
Alternate Clients and Tools
For YouTube, the community has created alternatives.
- ReVanced (successor to YouTube Vanced) is a modified YouTube app with built-in ad blocking for Android.
- NewPipe is an open-source YouTube frontend that lets you watch without ads.
- On desktop, browsers like Brave have strong built-in ad blocking.
It is always recommended that you use a dummy account when using modified apps. Weigh the risks, as modded apps might violate the terms of service.
Private DNS Configuration
Modern Android phones (9+) allow setting a private DNS. Pointing it to services like NextDNS or AdGuard DNS provides system-wide blocking without installing apps. It won’t eliminate first-party ads, but it’s a quick win to cut down known ad domains.
Should I Just Pay for Ad-Free Versions Instead?
When the hassle of blocking starts to outweigh the annoyance of ads, official solutions are definitely worth taking a long, hard look at
- YouTube Premium basically stops all ads on YouTube across all your devices and includes extra features like the ability to watch videos with the screen off and the option to download videos. If you’re a heavy YouTube user on devices where blocking is such a pain (TVs, consoles, mobiles) and you value your time, then the subscription might be a worthwhile investment.
- Many apps let you pay to remove ads permanently. For a few bucks, you can get rid of ads in a game you’re really into and support the developers in the process.
- Before you even think about installing an ad blocker, always check your device settings and turn off any built-in features that are annoying you. In Gmail, for example, turn off that “promotions” tab. On Windows, toggle off all those annoying suggestion features. On your phone, go to the “Privacy Settings” and toggle off “Personalised ads”. On Amazon devices, sometimes it’s worth paying the small amount to get rid of all those annoying lockscreen ads.
The aim here is to have a user experience without the annoyances – sometimes that means throwing some serious tech at ads; other times it just means paying the services you want to support. You don’t have to choose one way or the other; you can mix it up – use an ad blocker for what you can, pay for the rest, and always have a snoop around in your device settings to see if you can find ways to turn off the stuff that’s really getting on your nerves without resorting to third-party tools.
The Bottom Line
Some ads can’t be blocked by traditional means because of how and where they appear — inside apps, from first-party sources, or woven into content streams. Understanding this arms you with realistic expectations and alternative strategies.
Deploy network-level defenses, such as Pi-hole or DNS blockers, to block third-party ads. Tweak privacy settings and disable recommendations in your devices and apps. For platforms you use frequently, consider alternative apps or paid, ad-free subscriptions. Each method has trade-offs, but combined, they ensure you, not the advertisers, have the final say in what you see on your devices.
