Google has some in store for us with some of the commented out lines of code.
One of them is “OK Google” Offline, which allows full hotword functionality without the need for a data connection. Whilst there’s inevitably limits with what information can be delivered without a data connection, caching and local data will be able to deliver most functionality for the hotword searches.
There are some strings within the Google App that reference Offline voice tips that indicate even without an active internet connection, cards can be displayed indicating what commands can be issued offline. The offline mode appears to be limited to making a call sending a text, playing music, and turning on WiFi.
There are some more features, like: insecure network warnings that will do just what it says, warn of networks that could be insecure and subject to potential attacks from traffic snooping. It does seem that there will be an override button to connect anyway and ignore the warning.
Another functionality include:
– Voice commands for brightness and volume
– Google Cast (disabled for now)
– Maps generated based on a users activity
– Reminders shortcuts
– A few icons that could indicate future baked in functionality
