Personal Choice
If I were choosing between these two phones, I would choose the Xiaomi Poco C40. The significant performance advantage, larger battery, slightly better display, better screen protection, inclusion of a fingerprint sensor, and features like slow-motion video and reverse charging make it a far more compelling option overall. While the Samsung Galaxy A02s has a dedicated macro lens, this is a niche feature that does not outweigh the multiple advantages the Poco C40 offers.
