When Android 10 was released, a handful of features discovered in previous betas were missing. Some of these features, including the Tasker-like "rules" and built-in on-screen recorder, may still be planned as they can be found on videos posted on a Google Photos page linked to an internal version of the Google Camera app which has since been shut down.
A video of the now removed page with a section "Rules" under "Settings -> System".
The expected "Rules" feature should provide similar functionality to other automation apps like Tasker or IFTTT. It should change settings or perform actions based on configurable triggers, but with the benefit of system integration.
Recall's notification and app icon in the videos.
The videos also display a "Callback" app on the Home screen, and at other times a running "Record" notification is displayed. Due to the obvious functionality and the fact that the notification text "Callback is being recorded", it is not too difficult to assume that this new Recall app is responsible for recording these videos. This is probably related to the screen recording feature that was detected in the Android Q-Beta / Android 10 and then removed. However, it could just be a tool for Google's internal use.
Volta as a target in the Share Sheet.
Outside With these "missing" features, a new Volta app was also shown as the target in the Share Sheet. We're not sure what it might be, though its symbol implies it has something to do with the power supply or the battery, possibly related to "Project Volta" from Android 5.0 Lollipop.
More details are included in the now removed version This page describes the increased attention of Google engineers for camera performance – not just for the camera-driven development teams, but for all Android devices. The page describes new priorities, including a "focal point" for focusing on "snappiness" and reducing slow start-up times of camera apps. Apparently, the Google Camera internal beta testers in the dog food version will be prompted to send logs and an error report if it takes too long to open the app so they can pin down the issues they are handling. (The same prompt apparently referred to the now removed Google Photos page, from which all this information is taken.)
All four videos from the album are available here: (1) (2) (3) (4).
With the names and strings revealed in these videos, we've seen some more detail over the coming weeks as people search the latest Android 10 images for references. Some of these features may also be announced along with Pixel 4 at Google's planned October event, but others may be for internal use only and may never see the light of day.
