My Choice
If I had to choose between the two, I would pick the Samsung Galaxy A02. The significantly larger battery is a crucial advantage for me. While the Oppo A53's 90Hz display is nice, the difference isn't significant enough to outweigh the benefit of much longer battery life. The inclusion of a macro lens is also a plus, as is the Dolby Atmos support. The lack of a fingerprint sensor is a downside, but I can live with it for the other benefits.
