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.
An Android Authority teardown of a recent Google app (15.45.43.ve.arm64 beta) has revealed a redesigned Circle to Search UI. This is a chunkier interface compared to the current UI, with the UI elements now encased in a rounded box. However, the biggest change is that we've now got an app drawer in place of the translate button.
