Samsung Galaxy S21 review: Right recipe, wrong ingredients


The Galaxy S21 makes a smart bet on value with a lower starting price, but in many ways feels stuck in 2020. A good phone, but not a particularly exciting one.

Slick and colorful hardware ; Excellent display ; Improved fingerprint sensor ; Lower price leads to great value

Plastic back on base S21 ; Not a 2021 flagship camera experience ; Galaxy S21+ value disappointing at $1,000

Samsung Galaxy S21 review: nice for the price


More than a refreshed Galaxy S20, but not by much.

Fast processor ; Nice screen ; Good battery life

Samsung bloatware ; Competition will undercut price ; No microSD storage expansion

The Samsung Galaxy S21 drops the price down to $800 while maintaining some key features. There is a fast new processor, but the screen and cameras are not going to amaze.

Samsung Galaxy S21 Review


Hand-friendly form factor ; Bright, colorful screen ; Better Night photo mode than previous Samsung phones ; Supports future 5G network features

5G battery life is just on the edge of acceptable ; Future network features don't exist yet

The Samsung Galaxy S21 packs plenty of power into its small stature and sets the stage for better 5G phone performance in the future.

Samsung Galaxy S21 review: A premium phone that's a great value


The Samsung Galaxy S21 isn't a huge upgrade over the S20, but it makes smart sacrifices to reach its best price in years

Beautiful design with a fantastic screen ; Great performance and battery life ; Subtle UI improvements make an overall better experience

Some users will miss the microSD card slot ; The camera is basically the same as the S20

When you boil it down, the Galaxy S21 isn’t all that different from the S20. It has the same size screen and the same camera, along with less RAM and a lower resolution. You’re also giving up a microSD card slot.

Samsung Galaxy S21 review


We take a deep dive with the Samsung Galaxy S21 and take a look at its camera quality and performance...

Great look ; Fast and snappy performance ; Full of features to explore ; Good camera quality ; Speakers are improved over last gen

Plastic back is a no-no at $800 ; The plethora of features can be overwhelming, take it slow ; The UI looks a bit flat and tacky ; Bye, bye, microSD card slot
