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?

is A15 the last good version of Android
Reason why I’ve disabled software updates.
don’t do this use GrapheneOS instead
Doesn’t work with s24.
Thank you, I’ve been wondering what’s going on

Shit like this is the reason I’ve given money to mobile Linux projects
Hell yeah, thanks for donating! For anyone else reading, I’d suggest donating to PostmarketOS, if you have the means. They’re doing extremely good work building the foundation we’ll be able to use to escape Android and google forever.
Any word on Signal working on Postmarket? That’s basically the only thing keeping me from switching, as I rely on signal daily. Whatsapp would be good, too, but I don’t mind having a dedicated, wifi only device for that heap.
From this page, it seems to still have problems, but I’m not sure how up-to-date it is.
I’m just curious how I’ll manage to get to my second factor app for my bank to run.
A lot of bank apps actually work fine on Graphene, there’s a list of working ones here: https://privsec.dev/posts/android/banking-applications-compatibility-with-grapheneos/
Nice, both my bank and Wero are listed. Do you think this can be adapted for postmarket?
It’s possible that the android app could be run through a compatibility layer such as waydroid, but that would need separate testing to confirm if the app is compatible.
Just tested on postmarketOS and both Aegis and my bank app work fine through waydroid. My bank alerts that my phone is somehow modified and that I should be careful.
So I guess they do detect it, but some banks may or may not allow you to use their app in that case. (My app works on graphene too btw)

I’m sure this will happen but I also know that we will be the first adopters so we will have to figure out how to communicate our wishes.
“Bug”
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.
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
Switching to a Pixel phone to access GrapheneOS would still be worth it, and a massive increase in privacy and security.
I am doing the opposite. If I have to use locked down system, I’ll use the one with better hardware and less spyware.
Would this affect android-based OSes like lineageOS? Or can they patch something like that?
On grapehene os and hasn’t encountered mentioned bug.
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…
Seems like they may have around this time
likely will affect them, but now that it’s been disclosed will probably get patched immediately (but not by google).
It has been disclosed for a while…
Yes to both?
Google will ban VPN apps next, I guarantee it.

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.

You’re right, I don’t actually know why they would ban vpns, other than governmental pressures. A bit of a knee-jerk, there. :)
So without even a law they would just do it.? Yeah knee jerk is a mild way of putting it
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.
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
That’s not their money. And they are not in this to be altruistic. I doubt they would care.
Besides, that’s always a feature they can restrict to some kind of business plan.
And to be frank, expecting any goodwill from them is dangerously naive. The very idea that Google, who are FAMOUS for randomly canceling projects and services, regardless of the impact, would so much as even notice the damage their actions cause is quite simply ludicrous.
I’m expecting the opposite of goodwill. I’m expecting greed. Companies don’t buy phones from companies that remove their ability to do work. A lot of large companies buy phones. Again: alarmist.
That explains a lot. Although I never had to restarty phone, my Mullvad occasionally just crashes for no reason and there is no indication.
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.
It’s a feature.
Especially considering the trend, yes, it’s definitely a feature.
