I'm not sure about other phones, but I know the Samsung S Series phones offer app shortcuts on the lock screen. From the lock screen, I could swipe up from either corner to quickly access any app (pretty helpful for camera).

Do you know if this capability is possible with Graphene OS... I know it's not stock but could a different launcher achieve this functionality?

Also just a side note, but it would be pretty great if I could use those lock screen shortcuts to quickly change user profile's. Or, if I could create a shortcut on my home screen to quickly change to another user profile.

On the lockscreen, I'm not finding any way to activate those shortcuts. On your home screen, you can have any shortcut available through apps like Activity Launcher or Activity Manager, I suppose.

The lock screen shortcuts are not very useful as they are now. I wanted to add Note-taking and point to Tasker as default app to trigger the opening of a specific app. This only to be able to open this specific app using one of the 2 shortcuts available on the GrapeheneOS lock screen. It's not working, the Note-taking app is hidden for some reasons. Has anyone faced that challenge of opening an app with a lockscreen shortcut?

    cybermattic My understanding is that multiple lock-screen features from Google's Pixel OS are not supported by GrapheneOS. In some cases that may be because Google hasn't contributed the relevant code to AOSP, on which GrapheneOS is based. But it is also possible that the GrapheneOS team hasn't had time to audit the security of various lock-screen features. For example, any lock-screen feature involving typing could add substantial amounts of attack surface, because keyboard apps can have bugs.

      de0u Duh! That's a bit arsh.
      On that use case I have reasons to believe Google has contributed to AOSP. As mentioned above the feature seems to be there and working fine, just the icon is hidden.
      Adding a toggle and let the user choose for himself would have been a bit less radical approach? But I get the philosophy: GOS doesn't believe the end user is capable of taking the right decisions for himself. Fair enough.

      My understanding is that the GOS's user base can roughly be split into 2 pools:

      • the high profiles, searching to secure at all cost
      • the nobodies searching for privacy and regain control over their phone kicking out Google's privileges.

      Why not warning on each sensitive features + a toggle, instead of just simply obliterating them?
      At the moment this implementation choice is not listed on the documentation, so the user find out when trying to configure the feature. It's quite an opinionated choice without prior notice.
      I'm worried about the future choices to come. It's not an attack, it's a concern from a 2nd pool's member.

      Actually I might be wrong but it seems this feature has simply not been audited yet. I tried adding the 'Device control' app instead, and it's locked down, you need to authenticate first, so my guess is it is the same for the 'Note-taking' app maybe.
      Anyway thanks for your answer @de0u
