What I Would Choose and Why

If I were choosing between these two phones, I would personally pick the Samsung Galaxy S21 FE 5G. While the Xiaomi Poco F3 is an excellent phone, and a much better value pick, my priorities are better camera performance with more features, a more premium experience, and wireless charging support. I value a device that can take high-quality photos, record good video, and has a good set of features for daily use. The Galaxy S21 FE 5G, while more expensive, fits my use case better. The improved camera system, especially the telephoto and wide angle lens capabilities, is a feature that would improve my experience and is worth the extra cost for me. The wireless and reverse wireless charging is also a great bonus that would improve my daily life.
