My Choice and Why

If I were making a personal choice between these two phones, I would absolutely choose the Samsung Galaxy S21 FE 5G.

Here's why:

As a tech journalist and smartphone analyst, I value performance and display quality above all else. The Snapdragon 888 chipset in the S21 FE is a massive advantage, ensuring smooth multitasking, snappy app loading, and excellent gaming capabilities. The 120Hz AMOLED display is a joy to use, making everything from scrolling through social media to watching videos a much more enjoyable experience. I also take my phone camera quite seriously. The S21 FE provides a very versatile set of features, great photo and video quality, along with a telephoto and wide angle lens. Additionally, the build quality, with the Gorilla Glass Victus front, will give the phone a much better chance of surviving a drop.

While the Redmi 10A is a good option for budget users, it makes too many compromises in performance, display, and camera quality. For me, the Samsung S21 FE 5G is an outstanding device that offers a premium user experience, one that justifies its higher price tag.

The S21 FE aligns much better with my needs and ensures I am getting a device that won't feel outdated for a couple of years at least.
