[BUG] Deleting does not work a expected / Backup discovery ignores IS_TRASHED flag on Android 11

The bug

This title is only an assumption. So apologies if I got it wrong :)

TLDR: After deleting photos in Android 11 using Immich, they will still be uploaded to the server even though they shouldnt be. I believe this is connected to #739 and #2748

Why I think this is happening: My understanding of the trash bin system in scoped storage (Android 11) is that when deleting a file it remains untouched but gets a new IS_TRASHED flag until it gets automatically removed after 30 days. The problem is, that when using the backup function, this flag seems to be ignored and the file gets uploaded anyway. (I have not tested if the flag is actually set because I dont know how to. But since the Android dialog poped up, I assume it is)

I had a look a the behaviour of the Google Photos app. Their approach seems to be to rename the photo to ".trashed_XXX". If Immich would do the same, it should be easy to filter photos that should be ignored during indexing (and it would also be clearer when using a file manager).

Android 11 (unrooted Havoc OS v4.19)

Reproduction steps

1. Be on Android >=11
2. Create a new user on the server
3. Download the android app and login as that user.
4. Select a folder for backup
5. Delete a photo from the device using the app (the photo will be gone from the gallery, but it will still be present using a file manager)
6. When looking at the "Remainder" counter in the backup section, the counter will be too high (if your folder had 5 photos and you deleted 1, it should show 4. But it still shows 5)
7. Manually backup your photos

Outcome: ALL photos (including the one deleted) will be backed up to the server. The app will show the file as if it were only on the server. but when using a file manager, it will still be present

Additional information

Btw even though there are still small issues (as expected after such a short development time :D ), I am really in love with Immich! Thank you so much for your hard work!

Great app. Really impressed. This is exactly what happens on my google pixel phone.

I can refine the bugreport:

deleted images on Android just disappear and do NOT end up in the trash. So there is a bug when deleting images in the mobile app. The above issue is a result of that

I have a similar issue. When I use the web interface to delete photos that were uploaded from the android mobile app, they are automatically reuploaded every time I open the Immich mobile app. Guessing the only way around this would be to keep some info about files that were deleted (filenames etc) and check that when backing up from mobile?

The app respects the IS_TRASHED flags. The assets are indeed renamed with to the same format as the other app (Android handles this automatically) and the backup excludes such assets. Kindly try the new beta timeline and open a new issue if it persists
