What I Would Choose

If I had to pick one, I'd lean towards the Samsung Galaxy S21 FE 5G. While I appreciate the Xiaomi's speed, as a tech journalist, I’m frequently taking photos and video, and the Samsung's more balanced camera, especially the Telephoto lens, would be more beneficial to me day-to-day. The wireless charging and the brighter screen are also big pluses. Although the Xiaomi would be a great gaming phone due to the more RAM, I don't do much mobile gaming. The fact that the Samsung has longer software support is also very appealing to me.

Ultimately, the best phone for you depends on your specific needs and preferences. Both the Xiaomi 12X and the Samsung Galaxy S21 FE 5G are excellent devices; it's all about which features matter most to you!
