What I would choose and why!
Given the choice, I would personally choose the Xiaomi Redmi A3x. While the Samsung Galaxy A12 has a better and more versatile camera system, the overall performance, snappier display, newer OS, and improved screen protection of the Redmi A3x outweigh the better camera system in the Samsung Galaxy A12 for me.
The fact that the Redmi A3x has a much newer chipset and a significantly higher AnTuTu score, coupled with a smoother 90Hz refresh rate, makes it a much more pleasant device for daily use.
