My Choice
If I were choosing between these two phones, I would choose the Samsung Galaxy A04. The significant performance upgrade, the far better main camera, the newer software, and the faster wireless connectivity make it the better overall choice. While the A02s does offer 15W fast charging, this advantage doesn't outweigh the performance and camera benefits of the A04. The fact that the A04 is a newer phone and offers newer connectivity standards make it the more future proof of the two as well. While macro photography and having more GPS systems are nice to have, for most users, the real-world difference would be negligible.
