  2. How important is camera quality? If you take a lot of photos, the M12's 48MP camera and ultrawide lens are superior.
  3. What is your budget? Consider the prices of each phone.

Scenario-Based Recommendations:

  • Scenario 1: You need a reliable phone for long workdays with minimal charging opportunities. Recommendation: Samsung Galaxy M12 (for its superior battery life).
  • Scenario 2: You want a lightweight phone for basic communication and navigation while traveling. Recommendation: Oppo A15 (for its portability and compass).
  • Scenario 3: You enjoy taking photos and videos on your phone and want the best possible camera within this budget. Recommendation: Samsung Galaxy M12 (for its higher-resolution camera and ultrawide lens).

What I would choose and why!

I would choose the Samsung Galaxy M12. While the Oppo A15 has the advantage of being lighter and having a compass sensor, the M12 offers a more compelling overall package for my needs. The significantly larger battery capacity is a major plus, as I value having a phone that can easily last through a full day of heavy usage. Additionally, the higher resolution main camera and the inclusion of an ultrawide lens would provide more versatility in my photography. Finally, the smoother 90Hz display would noticeably improve the user experience, making scrolling and animations feel more fluid. Although the M12 is heavier and bulkier, the benefits of longer battery life, a better camera, and a smoother display outweigh the trade-offs for me.
