If you prioritize a higher refresh rate for smoother navigation and scrolling, the Samsung Galaxy S21 is superior with its 120Hz display, but this might affect its battery life more than the Galaxy S10's standard 60Hz display. The Galaxy S21 also has an advanced processor and more RAM, which means better performance overall. For photography enthusiasts, the S21's camera system offers significantly better photo and video quality, with enhancements like a 64MP telephoto camera. However, the Galaxy S10 includes a headphone jack and a high-quality OLED display with a sharper resolution, which might be more appealing if those are priorities. Both phones have similar quality builds, with the S10 featuring a glass back and the S21 a plastic one, which might affect the phone's feel and durability. Lastly, if cost is a crucial factor, you might lean towards the less expensive S10, accepting that it has older technology. Give Feedback

Tom's Guide

Caitlin McGarry | October 2022
"The Galaxy S10 offers superfast performance and a beautiful display, with a less distracting camera cutout than on the larger, pricier S10 Plus. If all you're looking for is a well-rounded, well-crafted Android flagship that can do it all — including work with a pair of good old-fashioned wired headphones — for a price you can sleep easy at night spending, the Galaxy S10 remains an unbeatable proposition."

Huseman Joe | February 2022
"The Galaxy S21 delivers the flagship Samsung experience in a phone that's much more pocketable (and affordable) than the top-end S21 Ultra.The triple-camera system is incredibly capable, Samsung's One UI 3.1 software is chock-full of features and settings to mess with, and I've not once missed having expandable storage."
