If you're looking for a phone with a larger screen and a headphone jack, the Samsung Galaxy S10+ might be a better fit for you, also offering a slightly longer battery life. On the other hand, if you prioritize having a newer model with a more powerful processor and higher refresh rate for smoother visuals, the Samsung Galaxy S21 would be the way to go. Although the S21 has a plastic back compared to the S10+'s glass, it supports 5G connectivity which could be important for future-proofing. Both have similar camera capabilities, but the S21 has a higher resolution telephoto camera and slightly better overall camera quality. If these advantages align with your needs and you're willing to spend more, the S21 could be the choice for you. Give Feedback

"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."
