    The bug corrupts Android's network stack at the system level after a VPN update, causing users to blame their VPN provider.

    Restarting the app doesn't help, with the only fix being a full device reboot or VPN app reinstall, something which most users never figure out.

    This affects several VPN providers on Android 16, and only Google has the access to diagnose it properly.

    After 7 months of waiting, we're now asking publicly: Google, when are you fixing this?

    @protonprivacy I've had this happen to me on Mullvad, Proton, and my Wireguard link to my home router. And honestly, from the description, I think the issue may be even older, as I'm almost positive the DDG local tracker blocker used to do this.

    I had no idea it was an known issue in Android itself.

    Thanks for bringing it to light.

      If you're using ANY VPN on Android, you can help us by getting Google's attention to fix it.

      We first reported this bug to Google in September 2025.

      Others like @mullvadnet and Wireguard reported it even earlier, in August.

      Google's response? "I don't see anything unusual."

      Here's what's actually happening ⤵️

      As someone who's done plenty of Android testing in IPv6-mostly/only environments, this is not even slightly surprising, Android's networking state machine is a huge mess

        Making sure I'm reading this correctly:

        If you're running Android (or an Android variant) and your VPN app updates, the only way to stop this issue is to:

        1. Reboot your phone after the VPN update

        OR

        2. Keep the phone on, delete the VPN app, and reinstall the app

        Am I correct in reading that one or the other approaches will fix this?

        IE, restarting your phone after an update eliminates the need to delete and reinstall the app?

        (and thank you, and Google wtaf)

          Or we could stop the grift & circle jerk. Release your source code so we can make secure email a real standard. Stop releasing to the play store entirely & teach people to install their own apps safely.

          Start initiatives to teach children about public private keys, identity verification, trust, & best practices.

          Be a man proton.

          Or are the normie dollars making you salivate? With fascism on their doorstep, you do have more customers, better bank on their ignorance…

              MF J6 on a raft, this is why I see ads where I didn't expect them as VPN (Wireguard) is connected to a router using PiHole DNS.

                            You: I wish people knew how to do more

                            You: It seems like people don't want to learn

                            *makes algorithms reinforcing bias & ignorance

                            You: People seem so tribalistic in this post truth age

                            *refuses to teach because of "human nature"

                            You: This is a realistic view

                            How's that clown makeup look?

                            If someone is incompetent, they shouldn't use it. It isn't our job to make it accessible for those who are ignorant. Teach & Learn.

                                @protonprivacy @mullvadnet I had decided long ago not to use VPNs on Android because it didn't actually help. Connecting to the onion network and using Tor tools does kind of help but only solves half of the problem. far better to work from Linux instead of Android where you have the option but in my case that means not using the cell phone for that particular traffic or anything that requires real security.

                                    @protonprivacy Will Proton ever create / sponsor a cell phone OS to be a true google replacement?

                                    @semitones @protonprivacy To be a true Google replacement, all of the vendors would have to write their drivers so that they could be incorporated into either Android or this new probably Linux-based phone operating system. We already have solutions that work for one or two or twelve different models or vendors, but all of the rest of the cell phone ecosystem is currently out of reach. I propose an alternative, a version of Android that belongs to the community, but will use the vendor's drivers and can replace Google Android with the community android. Google will, of course, attempt to make that technically impossible and illegal if they can, because that's what monopolies do.

                                      Google has known about a bug that breaks VPN apps for 7 months, leaving users exposed with no warning or error, just a VPN app that stopped working in the background.

                                      If you're using ANY VPN on Android, you can help us by getting Google's attention to fix it.

                                      We first reported this bug to Google in September 2025.

                                      Others like @mullvadnet and Wireguard reported it even earlier, in August.

                                      Google's response? "I don't see anything unusual."

                                      Here's what's actually happening ⤵️

                                      We need an android alternative we the people own.

                                        @wpeckham @protonprivacy that would have to be a fork of android AOSP, right? To keep google from making breaking changes?

                                          Proton: "hey google is ignoring this issue, lets make them fix it"

                                          You: "you are not 1000% perfect, Proton! Man up! Greedy fucks!"

                                          Rudeness aside. There is a compelling reason to ditch google as fast as possible. Security and personal control. We need to rapidly shift the center from a market focus on helpless users who want to be fed and diapered to people that want to own their own lives before we get lobbied and legislated out of existence.
