  • Scenario 3: Photography Lover: If you enjoy mobile photography, the Xiaomi Redmi Note 10 is superior with its extra camera lenses, better resolution, and 4K video recording.
  • Scenario 4: Power User: For users that require fast, reliable performance, the Xiaomi Redmi Note 10 wins hands-down due to its better chipset and more RAM.

My Choice

Given my analysis, I would choose the Xiaomi Redmi Note 10. The superior display quality alone (AMOLED, higher resolution, brightness) makes a massive difference in daily usage, whether for browsing, watching videos, or reading text. Add to that its significantly better performance, vastly improved camera capabilities, faster charging, more features and the choice is very clear. The Samsung Galaxy A03 is a budget phone and the compromises are too big to ignore. While it offers a potentially longer software update cycle, that does not outweigh the vastly superior hardware of the Xiaomi device.
