Complete guide to blocking ads on Android phones and tablets using Private DNS, browser settings, system apps, and advanced methods.
Android is the world’s most popular mobile operating system, powering over three billion active devices. That massive user base makes Android a prime target for advertisers, and the result is ads everywhere: in your browser, inside free apps, in your notification shade, between levels in games, and even baked into the home screen of some manufacturer skins. The advertising ecosystem on Android is aggressive, pervasive, and — unlike iOS — largely unregulated by the platform itself.
The good news is that Android’s openness is also its greatest strength for ad blocking. While Apple locks down iOS and limits what ad blockers can do, Android gives you far more control over your device. You can change your system DNS with a single setting, install powerful ad-blocking browsers, use VPN-based filtering apps, edit the hosts file on rooted devices, and even configure your home router to block ads for your entire network.
This guide covers every ad-blocking method available on Android, from the simplest one-minute setup (Private DNS) to advanced rooted configurations. Whether you have a brand-new Samsung Galaxy, a Google Pixel, a OnePlus, a Xiaomi, or any other Android phone or tablet, these methods will work for you. Every technique is tested on real devices running Android 12 through Android 15, and we update this guide whenever Google ships changes that affect ad blocking.
The absolute fastest way to block ads on any Android device: enable Private DNS with an ad-blocking provider. It takes 30 seconds, works system-wide, and requires no app installation.
Android 9 (Pie) introduced a built-in Private DNS feature that lets you configure an encrypted DNS provider at the system level. When you point this to an ad-blocking DNS service, every app on your phone — browsers, games, social media, everything — has its DNS queries filtered through the ad-blocking provider. Ad-serving and tracking domains are blocked before they can load, system-wide, with zero apps to install.
This is, hands down, the easiest and most effective ad-blocking method for the vast majority of Android users. It works on every Android phone running Android 9 or later, requires no root access, no VPN, and no third-party apps.
Navigate to Settings âē Network & Internet âē Private DNS. On Samsung devices, it may be under Settings âē Connections âē More Connection Settings âē Private DNS.
Choose “Private DNS provider hostname” and enter one of these ad-blocking DNS hostnames:
# AdGuard DNS (recommended)
dns.adguard-dns.com
# NextDNS (customizable)
xxxxxx.dns.nextdns.io
# Mullvad DNS (privacy-focused)
adblock.dns.mullvad.net
# ControlD
freedom.controld.comTap “Save.” Open Chrome and visit any ad-heavy website. To verify DNS is working, visit dnsleaktest.com.
Some carriers and Wi-Fi networks block custom DNS. If Private DNS shows “Could not connect,” try switching between Wi-Fi and mobile data.
| Provider | Hostname | Blocks Ads | Blocks Trackers | Free |
|---|---|---|---|---|
| AdGuard DNS | dns.adguard-dns.com | â Yes | â Yes | â Yes |
| NextDNS | xxxxxx.dns.nextdns.io | â Yes | â Yes | â 300K/mo |
| Mullvad DNS | adblock.dns.mullvad.net | â Yes | â Yes | â Yes |
| Cloudflare | one.one.one.one | â No | â No | â Yes |
| Google DNS | dns.google | â No | â No | â Yes |
If you primarily encounter ads while browsing the web, switching to an ad-blocking browser or installing extensions in your current browser can eliminate web ads completely.
Firefox is the only major Android browser that supports full desktop-style extensions, including uBlock Origin — the most powerful ad blocker available. This combination gives you the strongest browser-based ad blocking on any mobile platform.
Download Firefox from the Google Play Store.
In Firefox, tap the three-dot menu â Add-ons â Browse Add-ons. Search for “uBlock Origin” and tap “Add to Firefox.”
Tap the uBlock Origin icon â Dashboard â Filter Lists. Enable “Annoyances” lists to also block cookie banners and social widgets.
Brave is a Chromium-based browser with built-in ad and tracker blocking. It requires no extensions — ad blocking is on by default. Brave is an excellent choice for users who want Chrome-like browsing without ads.
Samsung Internet supports content blocker extensions. Install AdGuard Content Blocker from the Galaxy Store or Play Store, then enable it in Samsung Internet settings under “Content Blockers.”
Google Chrome on Android has a limited built-in ad filter that blocks only the most intrusive ad formats. To ensure it is enabled: Chrome âē Settings âē Site Settings âē Ads â “Blocked on sites that show intrusive ads.” Chrome does not support ad-blocking extensions on Android.
For blocking ads in all apps — not just browsers — you need a system-wide solution. On non-rooted Android devices, this is typically achieved through a local VPN that filters all network traffic.
AdGuard for Android is a comprehensive ad blocker that works system-wide by creating a local VPN. It filters HTTP and HTTPS traffic, blocks ads in browsers and apps, and provides detailed statistics. The app is not available on the Google Play Store (Google prohibits system-wide ad blockers), so you must download it directly from AdGuard’s website.
# Download from official site (not Play Store)
# 1. Enable "Install from unknown sources" for your browser
# 2. Visit adguard.com/adguard-android/overview.html
# 3. Download the APK and install
# 4. Open AdGuard and follow the setup wizardBlokada is a free, open-source ad blocker that uses the local VPN method. It is available on the Play Store (Blokada Slim, DNS only) and from their website (Blokada full, with advanced filtering). The community-driven filter lists are regularly updated.
DNS66 is another open-source option available through F-Droid. It uses a VPN to intercept DNS requests and block ad-serving domains. Lightweight and battery-friendly.
VPN limitation: Android only allows one VPN at a time. If you use a system-wide ad blocker that creates a local VPN, you cannot simultaneously use a traditional VPN for privacy. Some ad blockers (like AdGuard) support SOCKS5 proxy upstream to work alongside VPNs.
If your Android device is rooted, you have the most powerful ad-blocking option available: editing the system hosts file. By mapping thousands of ad-serving domains to 0.0.0.0, you block ads everywhere — in all browsers, all apps, all services — with zero performance overhead and no VPN required.
# Edit hosts file (requires root)
su
cp /etc/hosts /etc/hosts.backup
curl -sL https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts -o /etc/hosts
echo "Hosts file updated"AdAway is the most popular hosts-file-based ad blocker for rooted Android devices. Available on F-Droid, it provides a graphical interface for managing hosts file sources, whitelisting domains, and automatically updating the blocklist.
For non-rooted devices, VPN-based filtering is the most comprehensive ad-blocking method. Apps like AdGuard, Blokada, and DNS66 create a local VPN tunnel through which all network traffic passes. The “VPN” is a local loopback — traffic does not leave your device. Battery impact is minimal, typically 1–3% additional drain per day.
YouTube ads on Android are among the most difficult to block because Google serves ads from the same domains as video content. Your options:
For the best YouTube experience without ads on Android: use Firefox with uBlock Origin and visit youtube.com through the browser instead of the YouTube app.
Samsung Galaxy devices have additional ad-related settings worth configuring:
Go to Settings âē Privacy âē Customization Service and toggle it off. Then go to Settings âē Privacy âē Ads and enable “Opt out of Ads Personalization.”
Install AdGuard Content Blocker from the Galaxy Store, then enable in Samsung Internet âē Settings âē Content Blockers.
Some Samsung apps send promotional notifications. To stop them: Settings âē Notifications â find the offending Samsung app â disable marketing categories.
For the ultimate ad-free experience across all your Android devices, set up network-level DNS blocking using Pi-hole or AdGuard Home on your home router.
# On your router admin panel:
# Change DNS servers to Pi-hole or AdGuard Home IP
# Example: 192.168.1.100
# Or on Android per-network:
# Settings > Wi-Fi > tap network > edit
# Advanced > IP settings: Static
# DNS 1: 192.168.1.100 (Pi-hole IP)
# DNS 2: 1.1.1.1 (fallback)| Method | Root Required | Blocks Web Ads | Blocks App Ads | Difficulty |
|---|---|---|---|---|
| Private DNS | â No | â Yes | â Partial | Beginner |
| Firefox + uBlock Origin | â No | â Yes | â No | Beginner |
| VPN Ad Blocker | â No | â Yes | â Yes | Intermediate |
| Hosts File (Root) | â Yes | â Yes | â Yes | Advanced |
| Pi-hole (Network) | â No | â Yes | â Partial | Advanced |
No. Encrypted DNS adds negligible latency (typically less than 5ms). In practice, blocking ads actually makes browsing faster because ad resources never load.
It depends on the source. Trusted sources like the official AdGuard website, F-Droid, and GitHub releases from known developers are safe. Never install APKs from random websites.
Occasionally, yes. Some apps check for ad blocker presence and may refuse to work or show blank spaces. If an app breaks, whitelist its domain in your ad blocker’s settings.
With Private DNS enabled, your DNS queries are encrypted (DNS over TLS). Your carrier can see you are using an encrypted DNS service, but cannot see which domains you are querying. This is actually a privacy improvement over unencrypted DNS.
