I recently set up an immich server and I'm having a great time with it!
In fact, it works so well that I dug up some old devices to back up those photos too
Now, it went flawlessly with my current and last device, but I have an old tablet stuck on android 5.0.2 (lollipop) and the app unfortunately doesn't go that back
I can compile the app, if a change in the sdk version is all that's needed for it to work, but I think that it wouldn't work anyways due to missing android APIs
Now, i theoretically could also just upload them from the web interface (buuut... the old preinstalled browser on android 5 isn't rendering even the login page, and no browser I've found still supports those versions of android) or move the files to my pc/another smartphone and upload them from there, but (at least with the way I did it) that resets the file's created by metadata, resulting in all the images being in today's date, instead of 6+ years ago like they should be.
Now, before going on a journey to do this, has anybody else run into the same problem, and what was their solution? adb pull? something else?
