Galaxy S20 vs. S10 specs compared: What Samsung changed in 2020

Here's what makes Samsung's current Galaxy S20 phones different than last year's Galaxy S10s.

From left to right: the Galaxy S20 Plus, the Galaxy S20 Ultra and the Galaxy S20.

This story is part of Samsung Event, CNET's collection of news, tips and advice around Samsung's most popular products.

Samsung announced several new Galaxy phones this fall: the Galaxy Note 20 and Note 20 Ultra, Galaxy Fold 2 and Galaxy S20 FE. So it's a good time to revisit the company's current flagship phones, the Galaxy S20, S20 Plus and S20 Ultra. The phones are available online and in retail stores. Since their launch earlier this year, CNET has tested the S20 Ultra's impressive camera zoom, compared the Galaxy S20 to the iPhone 11 and conducted drop tests. We also compared the S20 to the S20 Plus and S20 Ultra, and more recently compared the S20 FE to the rest of the S20 line.

All the Galaxy S20 phones share high-end hardware, 5G connectivity and screens with a higher, 120Hz refresh rate. But they also have key differences among each other, too. The 6.2-inch Galaxy S20, for example, is the smallest of the bunch, followed by the S20 Plus and the S20 Ultra, which has a 6.9-inch display. 

In addition, the Galaxy S20 and S20 Plus both have wide-angle, telephoto and ultrawide cameras, but the S20 Plus and the S20 Ultra each have one extra camera. This fourth is a time-of-flight camera that measures depth for AR applications. Because the phones belong to Samsung's marquee line, they're expensive. The S20, S20 Plus and S20 Ultra start at $999, $1,199 and $1,399, respectively, though the S20 Ultra is currently selling for a reduced price of $1123. (International prices are £799, £999 and £1,199; or AU$1,349, AU$1,499 and AU$1,999.)

As well as 5G and the higher refresh rates, the Galaxy S20 devices can hold more expandable storage compared to last year's Galaxy S10 line, they shoot 8K video (rather than just 4K) and they run Samsung's second generation of its One UI out of the box.
