I currently use Simple Gallery. While it is not bad, the UI could definitely be better. I tried Aves for a bit but it seems to not have a built in photo or video editing feature which is a deal breaker (unless there is a version with those features?) Any suggestions?
I’m pretty happy with Simple Gallery by Simple Mobile Tools. These guys make great minimal FOSS apps that respect your privacy. Just make sure to download it from F-Droid, since the Google Play version doesn’t have all the features. If you dislike F-Droid, you can also use Obtanium to directly pull from their GitHub repo. It also notifies you whenever an update is available, and it allows you to download and install new versions of an app.
