It was only with the last Pixel 4 (XL) that Google introduced the new contactless gesture control. For this purpose, the Soli Radar chip was specially developed and installed, which also led to an ugly thick border at the top of the devices.

But as is sometimes the case, the users weren’t really interested in gesture control, there were some games and a few new gestures – and that’s about it. Sometimes the good old operation with the touch of the display is the best.
And so the technology should no longer be used in the Google Pixel 5 (XL). This saves space again and presumably it also makes a difference in the price.
