Two sets of images related to the upcoming Pixel 4 have appeared today. In addition to the earlier renders, the Pixel 4 for the first time (that we know of), noted the ice maker IceUniverse earlier tweeted out a pair of photos showing off what seems to be either the front-facing glass for the Pixel 4 and 4 XL or screen protectors for the two phones. Either way, and honkin 'cutout on the right side of that now-familiar top bezel raises some questions – or potentially answers them when it comes to those "Face Authentication" details spotted in Android Q.

That large oval-shaped opening appears in conjunction with both the Pixel 4 and 4 XL on the right of the earpiece, and we think it could be connected to those "Soli" rumors that were previously circulating in connection with the Pixel 4.
The best shot of the cutout in the top bezel on the Pixel 4 XL. Project Soli, if you do not remember, was a radar-based system that was previously used for mapping movements such as hand gestures for computer recognition. It is possible that in the four years since Google first demonstrated the tech, Soli's skills and effective resolution may have expanded.
Mix in the other rumors that Pixel 4 would debut a new Face authentication feature – expected to serve similar to Apple's Face ID for biometric security and authentication – plus the fact that this large oval cutout is clearly meant to provide optical or RF transparency, and it's not a big jump to think that something like a solo based radar emitter and receiver or, at least, some other optical or RF-based depth-mapping sensors could live up there
At this point in the game, it's still speculation, either raising or answering questions depending on how much of a logical leap you I'm glad to make it, but there's clearly something hiding to the right of the earpiece
Though Google jumped to show off the Pixel 4 early this year, the precise tech details probably will not be revealed by Google itse lf until the Event made by Google for the Pixel 4, expected to happen as per tradition in October. In the meantime, our curiosity will be tempered by patience as we wait for more leaks.
