Techsaw The issue is that the fingerprint button prompt does not even show up.

Are we really sure this is not an issue with GrapheneOS "End session" functionality? I have managed to get it to work again after using the "end session" button. If I recall correctly, the "end session" button showed up even after I ended the session on the only extra profilr. I tap the button and the fingerprint prompt came back again without reboot. This is quite inconsistent though, it doesn't work every time.

    A work around for this is to open any other app within the Owner Profile that uses a biometric fingerprint.

    For whatever reason this triggers the OS to work properly again for me anyway.

    I have a banking app I use or even my Gallery App's Fingerprint Protected folder does the trick. This workaround has been repeatable since the issue began some time ago.

    Give it a try, see if it's repeatable and report back.

      Another workaround I've found is to go into the Fingerprint Unlock settings under Security. As soon as I enter my PIN, the functionality returns.

        Any update on this? Maybe Android 14 is going to fix it?
        As of now (9 October 23) I'm still seeing this bug virtually everytime I switch profiles.

          Skyway Factory resetting? Pretty tall task for OS without a good backup solution. It would be great if either mods or developers chimed in on whether this this will resolve the issue for good.

            Skyway thanks. Good to know there is some kind of a fix, but that's way too drastic for me. Combined with the fact that Seedvault never worked on my phone, I can't really wipe it...

            Gonna keep waiting and hoping for an actual fix.

              IksNorTen same as you installed via web browser .
              I initially tried I factory reset but it didn't fix it so I did a reinstall .

                  Skyway Please can you tell me a few things :

                  • If I do this I'll lose all my profiles, true ?

                  • How can I backup safely all my apps and files ?

                  • Is it the only way ?

                      IksNorTen it will be like a new install , yes .
                      I had to backup my files , pictures, individually via desktop . texts , call logs and contacts via SMS import export app. Signal has a built in backup feature . as for other apps you will have to see what's offered . seedvault is useless.

                          IksNorTen Before you go erasing your entire device, you might want to cross reference what your read on here. I'm not saying it won't solve the issue, but I haven't seen any proof. Just because someone somewhere is claiming they're not experiencing it after reinstalling OS is nothing to go by. I don't experience it for days at a time until I do.

                              Skyway No, with Android 14 started this issue on my phone. With Android 13 never had this issue. Fingerprint shows up quickly and is replaced by the lock, so I need to enter pin every time.

                                  Same problem here: fingerprint unlock through different profiles doesn't work. I'm a new user, but I'm surprised that this bug has been going on for months. The only solution know so is a complete re-install? :(

                                    simono The only solution know so is a complete re-install? :(

                                    No indication any of this works, please don't factory reset or reinstall for nothing. GitHub issue is still there.

                                        [deleted] Thanks mate, will follow this thread and the GitHub's one to monitor things
