Final Recommendation
If I had to choose between these two phones, I would choose the OnePlus 12R. Although the Samsung A42 5G offers an AMOLED display with dedicated portrait and macro lenses, the OnePlus 12R significantly outclasses it in almost every other important aspect, including performance, display quality (resolution, brightness, refresh rate), battery life, charging speed, video recording capabilities, more advanced software, and connectivity. The massive performance difference offered by the Snapdragon 8 Gen 2, in addition to the 120Hz refresh rate and 100W charging makes the OnePlus 12R a compelling device. For my needs (high performance, media consumption, photography, and gaming), the OnePlus 12R's benefits heavily outweigh the few advantages of the Samsung A42 5G. The 12R is a much more versatile, more modern, and better overall device.
