Mullvad Release 2025.9 with QUIC Obfuscation

Different people may have different experiences with Mullvad depending on where they live and what kind of network they are on.

But DAITA inherently will slow things down and if you multi-hop to get DAITA, it’s even slower. I get that.

But that still doesn’t mean it is useless as the other claimed. It can be considered useless to you/people facing this issue to an extreme degree but is not useless at large because it can still work.

Semantics is what this debate is coming down to and of course, difference of experience with the tech itself.

Any news when Quic will be available on Android/iOS?

It’s coming.. no hard timeline as far as I know.

Now available on Android in Beta Release android/2025.8-beta1 · mullvad/mullvadvpn-app · GitHub

I can confirm that it now available on iOS!

I can’t seem to get Quic working on a 5G cellular connection though. It just doesn’t connect. Quic does work on WiFi, but it’s very slow even on a gigabit fiber connection.

I strongly suspect an issue with Mullvad’s QUIC implementation on Android. On the same Wi-Fi network, QUIC performance on Linux is significantly faster than on Android. Could you test and compare QUIC performance between your computer and your iOS device?

All obfuscation methods exist not for speed or performance, but for combating censorship where internet is highly restricted.

I think focusing on speed and performance is asking the wrong questions. Also, it’s a brand new update and there could be many variables. Location, time of day, etc. I don’t think there’s any real answer here that would be conclusive.

Also, welcome to the forum!

Thank you! And I apologize for speaking vaguely. What I meant was that when I use QUIC on Android, after connecting, when I browse random sites (for example, Google), after a short while, I can no longer access any sites. This isn’t just specific to websites, either. For example, when this happens, if I open the Telegram app, it gets stuck saying it’s connecting. However, while all this is happening, the Mullvad app shows me as being connected to the VPN without issue. But on Linux, even though I use QUIC on the same Wi-Fi as the Android device, I don’t experience any problems. That is why I said I strongly believe there is an issue with Mullvad’s Android QUIC implementation. And I would be very grateful if one of us could test QUIC on both a computer and an Android device on the same Wi-Fi network, compare the results, and report them. That way, I would understand if the problem is unique to me. I am trying to speak as little vaguely as possible. I apologize if I am still speaking vaguely.

There would still be many variables like I said. It would be hard to say conclusively.

But yes, QUIC is slow on Android.
