My Choice
If I were choosing between these two phones, I would unequivocally choose the OnePlus 12R. The differences in performance, display quality, camera capabilities, and overall user experience are so vast that it's hard to justify choosing the Samsung Galaxy A02. The OnePlus 12R provides a much more complete smartphone experience.
The faster processor, higher-resolution display, significantly better camera system, and rapid charging make the OnePlus 12R suitable for a wide range of tasks, including demanding ones like gaming and video editing. While it costs more, the investment results in a significantly higher-quality phone that will last longer and perform better for years to come. The lack of expandable storage is a small tradeoff for the other advantages. The Samsung A02 simply cannot compete.
