My Choice
I would choose the Xiaomi Redmi Note 9T. The difference in performance between the two phones is significant, and it far outweighs the benefits of a slightly newer operating system in the Samsung. The 9T offers a much sharper display, significantly better processing power (as shown by the AnTuTu benchmarks) a more robust camera system and better audio. It also provides much faster charging and a fingerprint sensor for added security. While the A03 is sufficient for basic tasks, the 9T provides a much better and more modern smartphone experience for the user. Given that they are in the same budget category, the 9T is the obvious winner for value.
