Google Lens is Google's image recognition service that delivers information from Google search based on whatever you're pointing your camera at. Last May, Google redesigned the Android version of the service by splitting the UI into 5 different scanning modes: Translate, Text, Search, Shopping, and Dining. In version 11.3.7.29 of the Google App, the app that contains the Lens service, we discovered that Google is working on a sixth service: Education. We also learned that Google is preparing to allow you to use Lens' Translate mode while offline.
An APK teardown can often predict features that may arrive in a future update of an application, but it is possible that any of the features we mention here may not make it in a future release. This is because these features are currently unimplemented in the live build and may be pulled at any time by the developers in a future build.
Offline Translations
New strings in Google App 11.3.7.29 reveal that you'll be able to download language packs so you can translate text using Lens without an Internet connection. The strings do not reveal which languages will be supported, but you'll likely be able to download most of the languages that Google Lens already supports. Notably, the Google Translate app supports offline translation in its "Camera" mode, which is functionally very similar to the Translate mode in Lens.

Education Mode
Next up is a new "Education" mode that we managed to briefly surface. The description for this "Education" mode informs the user to "point at [a] homework question to get help." We weren't able to test this feature, sadly, but a brief analysis at the Google App's code reveals you'll be able to use the Education mode to scan math problems. We don't know if Education mode will support complex math problems, though.
You can download the latest version of the Google Lens service by grabbing the latest beta version of the Google App. The Lens application from the Google Play Store is simply a shortcut to launch the service rather than a standalone app.
