Galaxy Note 9 vs Pixel 3: Design
While both phones have huge screens on the front, that's pretty much where the similarities end in terms of the design.
Both companies will use a long and skinny screen, metal materials, water-resistance and high-end cameras. The differences are the location of the fingerprint scanner, the curved screen, S-Pen stylus, cameras and the overall style.
Google is using a single rear camera again, but that doesn't mean the dual Galaxy Note 9 is better. The Galaxy Note 9 finally has a centered fingerprint scanner, just like Google, making that feature nearly identical on the back.
Another thing to keep in mind is both phones have an IP68 dust and water-resistant rating, and they both have wireless charging too. Yes, Google finally added wireless charging, we're just not sure how fast it is. Samsung's Fast Wireless Charging with 10w is faster than most on the market.
Aside from some of those visual differences (and the curved display), the only other big difference is the notch in the screen, dual cameras and the S-Pen stylus.
