Google’s flagship smartphone launched last year — Pixel 4, had an in-built radar. This was the reason the device was available in selected regions only. However, the company has ditched the Soli radar for this year’s flagship smartphone — Pixel 5.

This means that the “Motion Sense” feature on the smartphone is gone. Does this mean that the Soli radar sensor is gone for good? Well, apparently not. Google’s Rick Osterloh has said to The Verge that Project Soli radar and gestures will return.

He said that the sensor will be used in the future. Explaining why it didn’t make it to this year’s phone, he said that they were too expensive for the phone that the company had planned to make this year.

But note that Rick Osterloh has not confirmed if the hardware will be included in a smartphone in the future. A recent FCC filing had revealed that it might appear in the Nest smart thermostat.

For those who are unaware, the Project Soli on the Pixel 4 smartphone allowed users to wave above the phone to play/pause and skip tracks, as well as dismiss calls and alarms. However, it’s use-case in Pixel 4 didn’t expand much beyond what Google initially offered.

It was started as an experimental project within ATAP and Google spent several years in research as well as in making the radar smaller in size. The company has positioned the air gestures as the future of controlling devices, so it seems likely that the company will keep the technology around and will experiment with it on different types of devices.
