after reading this i did eventually learn that there is app pinning on android (or atleast grapheneos?) ! did not know about this might come in handy.

Tap Security & Privacy > More security & privacy > App pinning. After that is enabled, if you want to pin an app, open it, swipe up into the recent-apps view, tap the icon of the app above the preview pane, and select “Pin”. The feature is buried a bit. I believe this is because it’s more of a best-effort protection. The settings page itself says: "When an app is pinned, the pinned app may open other apps and personal data may be accessible. If you want to securely share your device with someone, try using a guest user instead.

    Not just GrapheneOS. Any Android phone has app pinning.

    And for the camera roll problem. I use Ente Photos and the app has that. You can select a range of photos and tap “guest mode”. Then trying to scroll outside the selected photos requires to unlock the phone.

      Good to know. I use Fossify Gallery, don’t think they have this.
