Pixel 3a vs Pixel 4

Swappasaurus says...

Upgrading from a Google Pixel 3a to a Pixel 4 means seeing improvements in almost every aspect of the phone. The display size stays almost the same, 5.6-inches compared to 5.7-inches on the Pixel 4. But the Pixel 4 adds HDR support and Smooth Display for an (up to) 90hz refresh rate. The Pixel 4 has a 2800 mAh battery with fast wireless charging, a soft-touch glass back and is water-resistant. Other features of the Pixel 4 include a Snapdragon 855 processor, 6GB of RAM, up to 128GB of internal storage, an 8MP wide-angle camera on the front, with a 12.2MP dual-pixel and 16MP telephoto setup on the back.
