I have a TrueNAS server at home and thought I could easily connect it to my phone (Pixel 7) as a network drive but was surprised to learn that Android doesn’t have a built in feature for that.
iOS/iPadOS does have this to my surprise built in via the ‘Files’ app.
Or did I just not look hard enough in the Android settings? (I know there are 3rd party apps for this)

The app in the first link is pretty old, just so anyone knows. If there have been vulnerabilities in the last 6 years this may not have addressed them.
