Safely display screenshot with phone locked?

aw22

Is there a tool that can easily display a screenshot with the phone locked?

For example, I'd like to screenshot an airline boarding pass and be able hand my phone to border patrol at the airport without allowing them to scroll through anything else on my phone.

I can almost do this by setting the lockscreen wallpaper, but it requires multiple steps and the clock and fingerprint reader icon partially obscures the image.

It's not the same security level as locking your phone, of course, but if it's enough to keep an employee from scrolling through your phone, you could try app pinning.

In GrapheneOS you'll find it under Settings> Security & privacy> More security & privacy> App pinning

aw22 there is this I cant speak for it's robustness as my inquiries about it were turned down due to the app not updated for years. Not sure how/if that translates to it's security, but functionality is superb imo and not clear why there is nothing alike anymore.

It displays QRs nicely fullscreen, but how do I get it to lock my phone while displaying a QR or image? I don't see any option for that.

aw22 Press the lock button while the QR is shown.

Press it later and the phone is locked but shows the app.

Thanks! That's prefect for my purposes.

Seems you already have a solution but I'll drop mine in here anyway.

I always opt to have boarding passes printed if the option is available. Otherwise, I solve this with a separate profile for travel, so any apps like airline apps would go in there. Before my travel I would load all documents I could possibly need, such as boarding passes and border crossing documents should I somehow lose access to my physical copies. My profile of course has personal information in it, but nothing more than I need for travel. I also use app pinning, as mentioned earlier in this thread, simply to block any attempts to snoop out of principle, even though extra personal information is already inaccessible.

This isn't necessary but to clarify my setup further, my primary profile is not the owner profile, so extremely sensitive data may be at rest while in the travel profile.
