The source is unknown, the photos are blurry and the information is contradictory. In other words: all signals are red. Still, we don't want to withhold these pictures of the possible Pixel 4a which looks nothing like an existing Pixel phone.
Thanks to the @onleaks renders we already know what the Pixel 4a will look like. A camera with a punch-hole and a square camera module with only 1 camera. The Google Pixel 4a thus promises an interesting and modern looking successor to the interesting Pixel 3a of 2019.
Roughly speaking, the photos somewhat similar to the @onleaks renders, but there are key differences. For example, the screen borders are much narrower and the punch-hole is not in the corner but to the right of the clock. In other words, there is enough doubt to give the advice to take this report with a grain of salt. What also doesn't help is that the source is new and has deleted its original message.
However, that Google will come up with a successor to the 3a seems certain. That model was one of the big surprises of 2019. It was something we never saw before; an affordable smartphone with a flagship camera. Earlier it appeared that the Google Pixel 4a probably has a 5.8 inch screen and a fingerprint scanner on the back. So it is not in the display and you cannot unlock it by facial recognition such as on the Pixel 4 and 4 XL.
