    • Do you take a lot of pictures and videos, and do you value high resolution and detail?

  • Scenario 3: Value User: If you would like to prioritize value, the Oppo Find X3 Pro would offer much more in terms of performance, camera, display, etc.

My Choice

Given the specifications and my role as a smartphone analyst, I would choose the Oppo Find X3 Pro.

Why?

While it's an older phone, the performance difference between these two phones is just too great. The Oppo Find X3 Pro excels in virtually every key area that influences user experience: performance, display quality, camera capabilities, charging speeds and overall feel. The Xiaomi Redmi A3 is a budget phone, and that difference is very stark. The newer software and slightly bigger battery of the Redmi A3 are not worth the massive reduction in overall performance.
