I really like the backup function in #GrapheneOS based on #Seedvault. I know it doesn't work 100%, some apps don't support it etc. But in my case >90% of apps get backed up and restored.

This is what all Androids should have. I understand #Google doesn't want to do it because for them #Android is just a gateway to their services and when you have all your data in their cloud, you don't need such backups. But other Android vendors should have it.
