If you're looking for a more budget-friendly option, the Samsung Galaxy S10 offers considerable savings. However, the Galaxy S21 Ultra provides a larger screen, longer battery life, and significantly higher camera quality for both photos and videos. The S21 Ultra also supports 5G connectivity, which could be important if you want faster data speeds and future-proofing. Bear in mind, the S21 Ultra is heavier and does not have a headphone jack, unlike the S10. If cost is not a primary concern and you value advanced features, the S21 Ultra might be the better choice.

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."
