Check out these renders which purportedly reveal the design of the upcoming Google Pixel 4. The renders were posted by iGeeksBlog, in partnership with OnLeaks.
There is no fingerprint sensor on the back suggesting that Google will go with facial recognition similar to Face ID. The smartphone is also rumoured to drop the 3.5mm headphone jack.
At the top right side of the forehead is a blank space where Google could place Soli Radar components for touchless gestures. At the back is a rounded square camera bump which will reportedly contain two lenses, a ToF sensor, and an LED flash.
