My Choice
If I were choosing between these two phones, I would choose the Xiaomi Redmi 9T. The Redmi 9T is the better phone in almost all metrics, especially performance, display quality, battery life, and camera capabilities. These are essential aspects that I value for daily use. The Redmi 9T's higher resolution screen, faster processor, much larger battery, and more versatile camera system make it a clear winner. Although it is negligibly larger and heavier, this is a small trade-off for the overall superior performance and feature set. The Samsung A02's slightly lower price is not enough to make up for the huge differences in performance and user experience. For any user that can afford the extra cost, the Redmi 9T is the superior choice.
