An APK teardown helps predict features that may arrive on a service in the future based on work-in-progress code. However, it is possible that such predicted features may not make it to a public release.

We dug into the beta version of the Google app for Android (version 15.36.40.29) and managed to switch on the Google Photos extension in Gemini. Google's official description mentions two main ways you'll be able to use this extension: "reminisce about past activities like photos of first food" and "use the photographic memory to remember information." This strongly suggests that the extension will basically use the "Ask Photos" and natural language search features coming to Google Photos.
