What improvements does Google Pixel 4 have over Pixel 3?

Google Pixel 4 has not been released yet, but people are already speculating about the potential differences that they have. Some will upgrade their Pixel 3 phones to Pixel 4 if they feel that there are specs that are truly worth it.

First of all, Pixel 3 only has one camera lens, but Pixel 4 is rumored to have two camera lenses that will make the pictures that will be taken more crystal clear. Pixel 4 is also going to have bezels located at the top and bottom portions of the display in order to fit in some extra sensors that the Pixel 3 does not have. The RAM of the Pixel 4 is also going to be much higher. Pixel 3 has 4G RAM while Pixel 4 will have 6GB RAM.
