Motion Sense will reportedly not be returning with the Pixel 5
While the Google Pixel series started out well, it is now having trouble keeping pace with rivals. Pixel 4 sales have apparently been poor, and part of it can be attributed to dismal battery life, the missing ultra-wide camera, and the design. With Pixel 5, Google reportedly plans to go back to the basics and give up some innovative features like Motion Sense.
A quick primer: The miniature radar enables certain things on the Pixel 4 that you cannot do on other smartphones. It can determine whether you are in close proximity to your phone to illuminate the always-on display, and figure out if you are trying to reach the phone to, for instance, fire up the Face Unlock sensor. In fact, the presence of the Soli chip is the reason why Pixel 4's Face Unlock works so seamlessly. And finally, it offers air gestures to let you perform certain actions such as rejecting a call or skipping an audio track.
Motion Sense also interfered with Pixel 4 sales in certain countries, as it couldn't meet radar regulations.
