Personal Choice

Which phone would I choose and why?

Given the specifications and my role as an expert smartphone analyst, I would choose the OnePlus 12. Although it comes at a much higher price point, the sheer improvement in display quality, performance, camera capabilities, and overall user experience makes it a far more compelling device for my preferences and use case.

The significantly higher AnTuTu score, superior AMOLED display with 120Hz refresh rate and higher resolution, faster charging, wireless charging, and vastly improved camera system with multiple shooting modes and better low light performance are key factors. The OnePlus 12 is not only a more capable device but also a more future-proof one due to its better performance and software support. While the Samsung Galaxy M12 is a decent option for a very basic phone, the difference in quality and features is too big to ignore.

Even if budget constraints were a significant concern, I'd rather consider a slightly cheaper but newer mid-range device than the Samsung M12.
