The Google Pixel 4a is coming on May 22 and it will have a punch hole for the selfie camera. The latter fact became clear from a seemingly innocent shared screenshot by Google's SVP of Hardware, Rick Osterloh.
The screenshot of him getting an Earth badge on Fitbit has a blank space in the top left corner that's reserved for the physical punch hole, which pushes the clock and the rest of the status bar to the side.
