About this app

Change DNS without root for fast internet, lower ping in games and safer, more private browsing.
DNS Changer by Protectstar™ lets you change the DNS server on your Android phone or tablet in seconds. Use a fast, privacy‑friendly DNS on Wi‑Fi and mobile data (3G/4G/5G) to reduce DNS lookup time, speed up websites and apps, and help stabilize latency for online gaming. Choose DNS providers that can filter many advertising, tracking and malicious domains at DNS level, and set up Family‑safe DNS for kids – all without root or complicated network settings.

Why change your DNS?
• ISP default DNS can be slow, overloaded or unreliable.
• A faster DNS can make browsing, search and streaming feel more responsive.
• Security‑focused DNS can help block phishing and malware domains before a page loads.
• Better DNS routing can help reduce ping spikes and lag in many online games.
• Fast & secure browsing starts with a DNS you trust.

Key features
• Change DNS without root on Android (no root).
• Works on Wi‑Fi and mobile data.
• Supports IPv4 and IPv6 DNS servers.
• Ready‑made profiles: Fast DNS, Privacy/Private DNS, Security DNS, Gaming DNS, Family filter DNS.
• Compatible with popular DNS services such as Cloudflare, Google Public DNS, AdGuard DNS, Quad9, CleanBrowsing and NextDNS – or add your own custom DNS (IPv4/IPv6).
• One‑tap connect/disconnect and clear status.

Gaming DNS
Use Gaming DNS profiles to help reduce latency and ping fluctuations. DNS can influence how quickly your device reaches game services, logins and matchmaking. Results depend on your network and region, so the built‑in DNS speed test (PRO) helps you choose a responsive DNS for your location and current connection.

Privacy, security and family filter
• Privacy‑friendly DNS helps reduce tracking and some third‑party traffic analysis.
• DNS filtering can block access to many suspicious domains before they load, which is especially useful on public Wi‑Fi (hotels, airports, cafés).
• Family‑safe DNS can help restrict adult content, gambling and other unsuitable categories across the whole device (all apps and browsers).

Use cases
• Faster daily browsing: shorten loading time for news, search and social apps.
• Streaming & video calls: better responsiveness on busy networks.
• Public Wi‑Fi protection: use a security DNS profile when you travel.
• Kids’ devices: enable a Family filter DNS profile on phones and tablets.
• Multiple networks: keep separate DNS profiles for Home Wi‑Fi and 5G.

Tips for the best results
• Run the DNS speed test at different times: the fastest DNS can change with network load.
• If a website or app fails to load with one DNS server, switch to another profile or return to system DNS.
• Some apps cache network results – restarting the app or reconnecting Wi‑Fi can help.
• Keep a “Safe” profile for public networks and a “Gaming” profile for play sessions.

PRO features
• Per‑app control: choose which apps should use DNS Changer (PRO).
• Advanced DNS logs and monitoring (optional) to see which domains apps connect to (PRO).
• WHOIS tool with map view for deeper network analysis (PRO).
• Save and switch profiles like Home, Work, Gaming, Kids and Travel (PRO).
• Advanced DNS speed test to find a fast DNS server automatically (PRO).

What DNS Changer is not
DNS Changer is not a full VPN service. It does not route your traffic through remote VPN servers and it does not change your public IP address. It is designed to manage the DNS server used by your device.

Technical note
DNS Changer uses Android’s VpnService API to create a local VPN interface and change only the DNS server used by your device. You generally cannot run another VPN app at the same time. Filtering results depend on the DNS provider you choose. Logging features are optional and designed for in‑app analysis – no browsing history required.

Ratings and reviews

If you're looking for something to block ads for the youtube app then this won't work, but it will work for everything else. If you use apps that use ads for rewards like webtoon then I'd suggest getting premium and turning off the changer for that specific app. If you turn on/off this while in the app you want to block/unblock ads on but it doesn't work then just close and reopen that app, it'll work then. To note: I use server AdGuard DNS.

Servers that say they block ads do not block ads. There is no indication that this is a paid feature. Internet is not faster at all. It's actually much slower and there's no indication that this is a paid feature or only available on some regions based on where the servers are.

I was hoping it would work. I wanted an easier way to switch to and from an ad guard DNS. This app doesn't do it. I still have to switch DNS through phone settings to block ads.
