  • Scenario 3 (High-Performance User): If you value performance, display, and camera quality, the Galaxy M55 is the clear choice.

My Choice

If I were choosing between these two phones, I would choose the Samsung Galaxy M55.

Here's why:

While the Galaxy M12 has the advantage of being older, and likely cheaper, the performance and feature jump with the Galaxy M55 are extremely high. The Snapdragon 7 Gen 1 chip offers significantly more processing power which would result in a much smoother everyday use, and is the core factor that outweighs other considerations. I prioritize a fluid user experience, which includes responsive apps, smooth multitasking, and high-quality media consumption, all of which are better on the M55. The superior display (AMOLED, higher resolution, higher refresh rate) provides a much better visual experience. And I'd also prefer the better camera quality. The faster charging is also a major plus for convenience. While the M12 has a dedicated depth sensor, I think the advantages of the M55 outweigh this single advantage. I am also a user who tends to keep their phone for a few years, and choosing the Galaxy M55 allows me to buy a phone that can handle newer apps, updates, and perform well for longer due to its more powerful specs.

In short, for me, the Galaxy M55's higher price is worth the improvements it offers in performance, display quality, camera capabilities, and overall user experience.
