• Google's Pixel 4 smartphone is expected to feature a new motion sensing technology called "Motion Sense" that will allow users to control certain functions of the phone without touching the screen. This technology, which is powered by Google's Project Soli radar chip, will enable users to perform gestures like waving their hand to skip songs or snooze alarms.

• The Pixel 4 is also rumored to have an improved camera system with features like a dual-lens rear camera setup and the ability to capture astrophotography. These camera improvements are expected to help Google's flagship smartphone compete with the photography capabilities of other leading smartphones.

• In addition to the new motion sensing and camera features, the Pixel 4 is expected to come with the latest version of Android, potentially Android 10, and may also include improved battery life and performance compared to previous Pixel models. The Pixel 4 is expected to be officially unveiled by Google in the coming months.
