Of course, no new feature is perfect, and Smart Search has a few quirks that need to be ironed out. For example, the scanning process that indexes your files for searching happens every so often, rather than in real time. This means that new files you download or add to your phone might not be searchable right away. Also, Smart Search can’t recognize locations in photos yet, even though the changelog said it could.
The new document scanner or the Drive shortcut is yet available for everyone in the latest version of the Files by Google app (v1.1737.587592893). This could mean that this could be a staged server side rollout, like many Google features tend to be. However, it appears that it is rolling out more widely now, so it should only be a matter of time before the feature appears on your Android.
