It's quite possible you triggered the issue by tinkering around with ADB or modifying the OS.

No, the system was not modified, root was not obtained, ADB was not used. There are 19 profiles in the phone. When the problem occurs, loading a another profile freezes for 30 seconds (possibly a coincidence).

You draw into question whether you're a reliable source of information based on doing that and the fact that you're now using / promoting a highly insecure OS with highly insecure modifications further compromising the security model.

I just described that the “other” OS has Firewall capabilities that allow to protect the user from such problems through allowed IPs. Because the “block traffic outside the VPN” option did not help at all in my case; and this has led to serious privacy issues.

It's quite strange for 2 people who know each other to have an issue which no one else seems to have.

I set up both of our phones. Both phones have many profiles (19 for me and 17 for my colleague). Approximately the same applications were installed (although it is unlikely that installed applications should affect and break system functions). Approximately the same settings were used.

    UndercoverBozo I understand, and thanks for the alternative client.
    But the problem is different: the “block traffic outside the VPN” option also breaks, which leads to traffic leakage.
    My message is mainly for this reason    . The blocking and anti-leak function should not break if the VPN service is not running or for some other reason...

      UndercoverBozo I'm not sure if the problem is with the client. Because in all cases when an error occurred, the loading of the profile froze for 30 seconds even before any applications started (at the stage before entering the user password), so most likely the system was unable to launch some modules (possibly due to a lack of RAM, although this is just my guess), and therefore there was a traffic leak due to a broken VPN service and the automatic disabling of the “block traffic outside of VPN” option.

      Moreover, the problem rarely occurs. Accordingly, if the problem were in the client, then the problem would always arise.

        kirillan10 You've sent a Settings app log. Need to see a full system log right after reproducing this issue, i.e. after switching to user profile and confirming that VPN is broken there. To capture a full system log, go to Settings -> System -> View logs.

            muhomorr Hello!
            I just sent you a new log.
            I no longer use GrapheneOS for serious things, but only for games and chatting, so leaks are no longer a big problem for me. But such traffic leaks outside the VPN when protection is enabled may well endanger other users who have faith in the reliability of the system.
            I ask you to look into and fix the problem.
            And as a wish: adding a Firewall option for applications, as is implemented in several other OSes (I can’t name them, since admins block people here for praising the functions of other OSes)...

                UndercoverBozo When I name third-party operating systems on this forum, my messages are edited or deleted by administrators. In any case, the current problem described above puts users' privacy at risk because it leads to traffic leakage, which the "block traffic outside VPN" feature does not help with.
