The popular no-root ad blockers on Android work by impersonating a local VPN. Blokada, AdGuard’s main app, and most of the others register themselves as the system VPN, filter your DNS or traffic, and pass everything else through. The catch is that Android only allows one VPN connection at a time. The moment you connect to NordVPN, ProtonVPN, Mullvad, or your work VPN, your ad blocker turns off. If you keep a VPN connected all day, you have effectively been browsing without an ad blocker. These are the seven best Android ad blockers that do not take the VPN slot, so you can keep your privacy VPN connected and still block ads in 2026.
Why the VPN slot matters
Android’s VpnService API is a single-slot system. One app at a time gets to act as the system VPN. Most popular no-root blockers (Blokada, AdGuard for Android, Personal DNS Filter, Adhell) all consume that slot. So do every real VPN: NordVPN, ProtonVPN, Mullvad, Surfshark, IVPN, Cloudflare’s 1.1.1.1 with WARP, and any work-issued VPN.
You cannot run two at the same time. Switching kills the other one. If you connect to a VPN, your VPN-slot ad blocker stops filtering until you disconnect, and vice versa.
The solutions in this list either operate at a different layer (DNS, browser, or hosts file) or have a built-in VPN that double-purposes as the ad blocker. None of them require root.

1. NextDNS, set as Private DNS
NextDNS is a hosted DNS resolver that filters ads, trackers, and malicious domains before your phone even sees them. The reason it pairs cleanly with a VPN is that Android’s Private DNS setting (Settings → Network → Private DNS) operates at a different layer from the VPN slot. You can have NordVPN connected and NextDNS resolving in parallel, with no conflict.
You sign up for a free NextDNS account, get a configuration ID, and enter the hostname under Private DNS. From that moment, every DNS query on the phone goes through your NextDNS profile, including DNS issued by apps that ignore the system VPN.
The free tier covers 300,000 queries per month, which is enough for typical single-device use. Heavy users or families on the same profile will need the paid tier, which is approximately three dollars per month. Filter lists are configurable in the NextDNS dashboard.
Where it falls short: DNS-level blocking does not stop ads served from the same domain as the content (YouTube on the official app, for example). For YouTube specifically, you still need a separate solution.
Download
NextDNS does not require an app for Private DNS mode. If you prefer an app to manage the profile, an Android client is available.
2. AdGuard DNS, configured under Private DNS
AdGuard offers a free DNS-over-TLS endpoint that you can paste straight into Android’s Private DNS field, no app and no signup required. The hostname is dns.adguard-dns.com. Once set, system DNS queries are filtered by AdGuard’s lists for ads, trackers, and known malicious domains.
This is the simplest VPN-compatible blocker on the list. There is nothing to install. It does not consume the VPN slot. It runs in parallel with NordVPN, Proton, or any other VPN.
The trade-off is that you do not get fine-grained control. Filter lists are AdGuard’s choice. If you want to tune what gets blocked, you either pay for AdGuard’s paid DNS tier (which adds a dashboard) or you switch to NextDNS.
Where it falls short: Same caveat as NextDNS for same-domain ads (YouTube), plus no per-device controls or query log unless you pay.
3. Brave, for browser-only blocking
If most of the ads you care about are on websites you visit in a browser, Brave is the cleanest answer. Brave’s shields block ads, trackers, and fingerprinting attempts at the browser level, with no VPN slot involved and no system permissions beyond what any browser asks for.
Brave is open source, derived from Chromium, and the rendering engine handles the same sites Chrome does. Shields are enabled by default for every site you visit, and you can tune them per domain. The blocking quality on common ad and tracker networks is genuinely strong.
Brave does not block ads in other apps. If most of your browsing happens in Brave anyway, that limitation rarely matters.
Where it falls short: Only blocks inside Brave. For other apps, pair Brave with a DNS solution above.
4. AdGuard Content Blocker for Samsung Internet
This is the lesser-known sibling of AdGuard’s main app, and it solves the VPN-slot problem inside a browser. The AdGuard Content Blocker is a plug-in that hooks into Samsung Internet (and a few other browsers that support the Android content-blocker API). It blocks ads, trackers, and unwanted elements at the browser level without using the VPN slot, without root, and without elevated permissions.
If you use a Samsung phone or simply prefer Samsung Internet to Chrome, this is the lightest-weight way to block ads while a VPN is connected. Filter lists are managed inside the AdGuard app, which itself does not need to be running in the background.
Where it falls short: Browser-only, and limited to browsers that support Android’s content-blocker API. Samsung Internet is the main one.
5. RethinkDNS, DNS-only mode
RethinkDNS is one of the strongest privacy apps on Android, and most users run it in the full DNS-plus-firewall-plus-VPN mode that takes the VPN slot. What is less well known is that RethinkDNS has a configuration where it runs as a DoH resolver only, set under Android’s Private DNS, with the firewall and connection-blocking features disabled.
In that mode it functions like NextDNS or AdGuard DNS: a hosted resolver applying blocklists at the DNS layer, compatible with a separately connected VPN. You lose the per-app firewall capability, which is the whole point of RethinkDNS’ main mode, so this is only worth doing if you specifically want RethinkDNS’ filter lists rather than its firewall.
For the full RethinkDNS comparison against Blokada and AdGuard, see our AdGuard vs Blokada vs RethinkDNS Android 2026 breakdown.
Where it falls short: You give up the features that make RethinkDNS distinctive. Worth using only if you specifically want its blocklists at the DNS layer.
6. AdAway, root or root-free hosts file
AdAway is the classic hosts-file ad blocker. The original version requires root and edits /etc/hosts directly, which bypasses the VPN slot entirely. AdAway also offers a non-root mode that uses Android’s VPN slot like Blokada does, so make sure you choose the root path if you want to keep your VPN running.
If you have a rooted Android device, AdAway is one of the most efficient solutions on this list. It costs nothing, runs nothing in the background (the hosts file is static once written), and works system-wide without holding the VPN slot.
Where it falls short: Root is increasingly hard to obtain on locked Android devices. If you do not have root and cannot get it (most users in 2026), AdAway in non-root mode reintroduces the VPN-slot conflict and is not appropriate for this list.
7. Pair a VPN that has its own ad blocker
Several VPN providers ship a built-in DNS-level ad blocker that runs as part of the VPN tunnel rather than as a separate service. The two layers are combined into a single VPN slot, which sidesteps the conflict entirely.
NordVPN’s Threat Protection Lite blocks ads and known malicious domains while the VPN is connected. Proton VPN’s NetShield does the equivalent on its paid plans. Mullvad ships a separate Mullvad Browser (a Tor-derived browser) but also offers DNS-level filtering through configurable Mullvad DNS, which you can point Private DNS at independently.
If you already pay for a VPN, check the settings: there is a strong chance an ad-block toggle is already there, free with the subscription. The quality varies by provider, but for general ad and tracker blocking, the built-in features are competent.
How to pick the right option
If you want one solution and you already use a VPN, the Private DNS approach (NextDNS, AdGuard DNS) is the cleanest. Set it once, it runs forever, no battery cost, compatible with everything.
If you mostly care about ads in browsers, Brave (or Samsung Internet plus AdGuard Content Blocker) is a smaller blast radius and equally effective for that use.
If you specifically want fine-grained per-app firewalling and you do not run a VPN all the time, the full AdGuard or RethinkDNS apps in VPN-slot mode still win. For that path, see our AdGuard vs Blokada vs RethinkDNS Android 2026 breakdown and the broader best no-root ad blockers for Android list. Just be aware they shut off when your VPN connects.
If you have rooted your phone, AdAway in root mode is the lightest, fastest, lowest-overhead option of all.
FAQ
Can I run an ad blocker and a VPN at the same time on Android?
Yes, if you use a DNS-level ad blocker (NextDNS or AdGuard DNS configured under Private DNS), a browser-level ad blocker (Brave), a content blocker plug-in for Samsung Internet, or a VPN that ships its own ad-block feature. The combination that does not work is two apps both trying to register as the system VPN, which is what Blokada and AdGuard’s main app do.
Why does Blokada turn off when I connect to NordVPN?
Both apps are competing for Android’s single VPN slot. When NordVPN connects, it becomes the active VPN and Blokada is suspended. Switching back puts Blokada in and disconnects NordVPN. This is an Android platform limit, not a bug in either app.
Is DNS-level ad blocking less effective than VPN-slot ad blocking?
For ads served from third-party domains (most banner ads, most tracking pixels), DNS-level blocking is equally effective. For ads served from the same domain as the content (the YouTube app serving ads from googlevideo.com is the classic example), DNS blocking cannot help because blocking that domain would also break the videos. For YouTube specifically, you need a different solution.
What is the easiest VPN-compatible ad blocker on Android?
AdGuard DNS via Private DNS. Open Settings, find Private DNS, paste dns.adguard-dns.com, done. No app install, no signup, no permissions. Filter lists are AdGuard’s defaults and update server-side.
Does Brave block YouTube ads on Android?
Brave blocks YouTube ads when you watch YouTube inside the Brave browser, including on Android. It does not block ads in the official YouTube app, because that runs outside the browser. Watching YouTube in Brave is the workaround.
Are these all free?
Mostly. NextDNS has a free tier (300,000 queries per month) and a paid tier (about three dollars per month) for higher volume and dashboards. AdGuard DNS is free with no signup. Brave, AdGuard Content Blocker, RethinkDNS, and AdAway are all free and open source. VPN-bundled ad blockers come with the VPN subscription you already pay for.
