After Google revealed the camera design of the Pixel 4, the smartphone started to pop up more frequently in random places. In another such incident, the Google Pixel 4 has allegedly been spotted in the London Underground. Although the phone is disguised with a thick back case to hide the camera bulge, the placement of the lenses and the LED flash confirms the camera setup that we have already seen in the official image shared by Google. We can see a main sensor along with a lens, which is suspected to be a 16MP telephoto lens. There is a spectral sensor above and a flash below the lens setup.
