If you're looking for a more affordable option, the Samsung Galaxy A15 is the way to go, but bear in mind its camera performance is considered poor and it has a plastic back. Should you prefer a better camera, glass back, and higher screen refresh rate, the Samsung Galaxy S21+ is superior, though it comes with a heftier price tag. The S21+ also supports HDR10+ for video, offers more RAM which can be beneficial for multitasking and performance, and it has wireless charging features, unlike the A15. The decision mainly hinges on your budget and the importance of camera quality and additional features to you. Give Feedback

"All told, Samsung nailed it with the Galaxy S21 Plus. It has most of the strengths of the smaller S21 in a bigger package. It’s got a lot going for it. If you’re coming from an older device, like the Galaxy S10 series, this is a solid upgrade."
