A post on APK Insight has revealed this information and it is reported that Google has decided to provide Audio Zooming feature for this latest version.This new feature allows you to adjust the audio level when you record a video, a feature already found on Motorola Edge Plus and iOS, but Google has yet to add it to its Camera app. .
A new motion blur mode is also being added to this version, enabling it to blur moving objects similar to a DSLR camera.
In addition, there is a new feature that can change the intensity of the flasher in the camera and share it on social media in its preview mode after capturing a video.
The update is now available for Pixel phones running the beta version of Android 11, so it's safe to assume that Google will be making it available to all Android users with the stable version of Android 11.
