Quote from Proton VPN:

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 Mullvad and Wireguard reported it even earlier, in August.

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

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?

Especially considering the trend, yes, it's definitely a feature.

[–] QuandaleDingle@lemmy.world 9 points 3 weeks ago (2 children)

Google will ban VPN apps next, I guarantee it.

[–] TrickDacy@lemmy.world 2 points 3 weeks ago (2 children)

What you didn't say was what reason you have for thinking they would do this. "They're getting shittier all the time" is true, but isn't an actual reason.

[–] skuzz@discuss.tchncs.de 6 points 3 weeks ago

The actual reason is control. VPN on the current Android stack makes it relatively easy for a non-technical user to sign up for a paid service that blocks telemetry-harvesting back to Google. Unlike Apple's platform, Google's historically heavily relies on a cloud connection for pseudo-real-time telemetry harvesting. If a person uses a VPN with ad/app/telemetry-blocking, Google gets cut off. That means things like, their Waymo cars not receiving real-time traffic updates, their WiFi geolocation database missing current information, their adtech arm not receiving user metadata.

Google's software is quite tenacious at attempting to connect to Google too. If you ever want to see how much, install RethinkDNS and start blocking core Google services. Check the logs. You will see the app try Google in your country, then Google in neighboring countries, then other devices in your home running Google software. Any connection they can find to relay telemetry back to the big G-spot.

Google's moves right now in lieu of any government taking action against them is to solidify their platform control and metadata harvesting pipelines. They're cutting off alternate ROMs, cutting off open source hardware drivers for newer devices, partnering with Samsung to encourage Samsung to close their devices down, reducing security patch frequency on older devices, partnering more closely with Apple to ensure a stream of healthy metadata from Apple, closing the ability to install third-party apps, and also getting heavier into military contracting.

Google is an information vacuum, always has been. When their leadership was more "altruistic", the trade-off was a contribution back to society. Now that they are in a late-stage profit phase, they're just doubling down on that vacuum role hard.

[–] QuandaleDingle@lemmy.world 0 points 3 weeks ago (1 children)

You're right, I don't actually know why they would ban vpns, other than governmental pressures. A bit of a knee-jerk, there. :)

[–] TrickDacy@lemmy.world 2 points 3 weeks ago (1 children)

So without even a law they would just do it.? Yeah knee jerk is a mild way of putting it

[–] forrgott@lemmy.zip -1 points 3 weeks ago (1 children)

Was there a law against ad blockers?

The answer is always to follow the money. With Google, you are the product. Your data is their money source. VPNs interfere with this.

The other guy us right. Google abso-fucking-lutey is going to ban em. Mark my words.

[–] TrickDacy@lemmy.world 0 points 3 weeks ago (3 children)

Ad blockers don't prevent work from being done. VPNs are used for work by many many people. Kinda alarmist and baseless to think they're going to disregard that

They will likely end up doing something similar to how Apple's network stack on iPhone works once they can figure out how to make the network stack work that way. Apple's devices are configured so even when you have a full-tunnel VPN, some local traffic, and connections back to Apple corporate always circumvent the VPN. There is no way to truly full-tunnel on an Apple device.

[–] Sophocles@infosec.pub 6 points 3 weeks ago (3 children)

Would this affect android-based OSes like lineageOS? Or can they patch something like that?

[–] GreenKnight23@lemmy.world 7 points 3 weeks ago (1 children)

likely will affect them, but now that it's been disclosed will probably get patched immediately (but not by google).

[–] Electricd@lemmybefree.net 2 points 3 weeks ago (1 children)

It has been disclosed for a while…

[–] GreenKnight23@lemmy.world 1 points 3 weeks ago

yes, but were the vendors that provide lineage/eos/etc aware of the disclosure?

probably not.

[–] moonshadow@slrpnk.net 2 points 3 weeks ago

Yes to both?

[–] Hiro8811@lemmy.world 1 points 3 weeks ago (1 children)

On grapehene os and hasn't encountered mentioned bug.

[–] forrgott@lemmy.zip 1 points 3 weeks ago (1 children)

I would honestly be surprised if the Grapheme network stack wasn't fully rewritten. So yeah, my money is this bug did not propagate to their codebase.

Any other android custom ROM I would be careful with, though...

[–] Calfpupa@lemmy.ml 2 points 3 weeks ago

Seems like they may have around this time

[–] Damarus@feddit.org 5 points 3 weeks ago

So that's why my AdGuard stopped working sometimes since the upgrade. I specifically set it to VPN mode as that used to be more stable than proxy mode.

[–] webkitten@piefed.social 3 points 3 weeks ago (1 children)
[–] Zanathos@lemmy.world 1 points 3 weeks ago

My self hosted wireguard has no issues, so no idea what this is on about... I leave my VPN connected for many hours at a time and never had a crash as this post is indicating. Sounds device specific, but have not seen the issue on my S22U or S26U.

[–] TankovayaDiviziya@lemmy.world 2 points 3 weeks ago

That explains a lot. Although I never had to restarty phone, my Mullvad occasionally just crashes for no reason and there is no indication.

[–] SailorFuzz@lemmy.world 2 points 3 weeks ago
[–] FEIN@lemmy.world 1 points 3 weeks ago (1 children)

is A15 the last good version of Android

[–] webkitten@piefed.social 1 points 3 weeks ago (1 children)

Reason why I've disabled software updates.

[–] nebulahhh@lemmy.blahaj.zone 0 points 3 weeks ago (1 children)

don't do this use GrapheneOS instead

[–] webkitten@piefed.social 0 points 3 weeks ago (1 children)
[–] nebulahhh@lemmy.blahaj.zone 1 points 2 weeks ago

Your still better updating than having unpatched vulnerabilities (it sucks that google is like this)

[–] Electricd@lemmybefree.net 1 points 3 weeks ago* (last edited 3 weeks ago) (2 children)

Wanted to switch from iOS to android but honestly I’m wondering more and more if that would even be useful

Also, the fact that the kill switch feature also kills LAN sucks

[–] ProdigalFrog@slrpnk.net 2 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

Switching to a Pixel phone to access GrapheneOS would still be worth it, and a massive increase in privacy and security.

[–] Electricd@lemmybefree.net 1 points 2 weeks ago* (last edited 2 weeks ago)

Frankly, since I would run sandboxed play services, it would still send massive amounts of telemetry to google, so eh, not so sure about privacy. It also knows all apps installed on the device. That's why microG is nice.

Security, yea, sure, but I'm not too worried about that.

[–] dukatos@lemmy.zip 2 points 3 weeks ago

I am doing the opposite. If I have to use locked down system, I'll use the one with better hardware and less spyware.

[–] VAK@lemmy.world 1 points 3 weeks ago

Thank you, I've been wondering what's going on

[–] dukatos@lemmy.zip 1 points 3 weeks ago

They also fucked up notifications somewhere around October - they are always 15-20 minutes late. I tried everything in settings, nothing helped. They are aware of the issue but they don't give a fuck.
