- Scenario 2 (Balanced Performance and Value): If you want a phone with a modern experience, better display, a significantly better camera, and faster performance, and you can stretch your budget, the A05s is the clear choice.
- Scenario 3 (Camera Focused): If your main priority is high-quality photos and videos the A05s is a better choice with its higher resolution sensors, the A02s PDAF is not enough to make up the difference.
- Scenario 4 (Gaming): The A05s is better equipped to handle basic mobile gaming with a better GPU and faster CPU.
My Choice
I would choose the Samsung Galaxy A05s. While both phones are budget options, the A05s provides a significantly better user experience in almost every aspect. The superior performance, notably sharper and smoother display, higher resolution cameras, faster charging, and newer software make it a much more compelling option. The differences are not trivial; they are actually very significant, it allows much better usability. The A02s, while cheaper, will be significantly slower, and the camera will likely not be enjoyable for most users, so it would be worth it to spend extra for the A05s.
