If I were choosing between these two phones, I would pick the Xiaomi Redmi 9T. Although the Samsung Galaxy A03 is slightly newer, the Redmi 9T significantly surpasses it in several critical areas that align with my needs and priorities. The Redmi 9T offers a far superior display, a noticeably larger battery with faster charging, a much more versatile camera system with additional lenses, and better overall performance with its Snapdragon processor. It also includes a side-mounted fingerprint sensor, stereo speakers, and better Wi-Fi and GPS capabilities.

The A03 being more up to date is important but does not beat the better screen and battery life of the 9T.
