I've stopped using Google Photos but haven't really found a suitable android app (or two separate ones) which can replace two main features:

1. One-click post-processing - I think Google called it something like "auto awesome", basically a single button which slightly tweaked brightness, contrast, and presumably a few other things to make snaps look a bit better
2. Automatic backup - I've tried proton drive but the app is a bit slow to load thumbnails, and critically it's a one-way copy so you have to manually re-delete everything from your phone

Any recommendations for apps which can replace these features? Doesn't have to be all-in-one, and FOSS is preferred!
