My Choice
If I were choosing between these two phones, I would definitely pick the Samsung Galaxy A15 5G. Here's why:
Even though the price may be higher, the improved experience of the A15 5G would make it worth the extra investment for me, as the difference in performance, display quality, and camera is significant. The AMOLED display with a 90Hz refresh rate would make daily use feel more fluid, and the better camera would be perfect for capturing daily moments. The improved performance would also be more future-proof, making the phone useful for longer. Additionally, the A15 5G's faster charging speeds would be a big plus for managing my daily usage. The A15 5G feels like a well-rounded device, while the A02 has obvious compromises that would make it unsuitable for everyday use. While the A02 might have a use case for those who prioritize extremely basic functions at the lowest cost, its outdated technology is too big of a compromise for me.
