My Choice
If I were choosing between these two phones, I would absolutely choose the Oppo Reno11. While the Samsung Galaxy A02 may have a slightly larger battery capacity and slightly better audio with headphones, the Oppo Reno11 is far superior in virtually every other aspect.
The Oppo Reno11 offers a significantly better display, with AMOLED technology, a much higher resolution, a faster refresh rate, and much higher peak brightness for daylight viewing. The processor is significantly more powerful and coupled with much more RAM, it offers a smoother experience across all usage scenarios. The cameras are also much better on the Oppo, with higher resolutions, optical zoom, a dedicated wide-angle lens, and better video recording capabilities including 4K. Lastly, the battery charges dramatically faster thanks to its 67W fast charging.
The differences are so large that the A02 feels outdated in comparison, and is really only competitive at the very bottom end of the market. The Oppo is simply a much better smartphone overall, that offers a vastly superior experience, and worth any premium that it may have in price.
