My Choice
I would choose the Samsung Galaxy A02s. While the Oppo A53's 90Hz display and fingerprint sensor are appealing, the significantly larger battery and versatile camera system of the A02s outweigh those advantages for my personal needs. I prioritize long battery life as I often find myself away from charging points for extended periods. The additional macro and depth cameras provide more creative options for photography, and the fact that it can update to a newer Android version is also appealing. While it doesn't have a fingerprint sensor, the advantages of the other features are too much to ignore!
