I use Google Photos as my photos app. I used to backup photos from another Android device when it was free to back up in reduced quality. I have noticed that some features (eg: Memories, face grouping, photo date editing) are only available for backed up photos, and not local ones. Is there a way to enable those features for local photos in Google Photos?
I assume all that happens on the server, so you couldnt do it locally
There are some self hosted options that do similar things
