4. Buying Decision Framework

Here are three questions to guide your decision:

  1. How important is a smooth display experience to you? If a 90Hz refresh rate matters, the A04s is the clear choice. If you do not care about the refresh rate the Redmi A2 will be just as good.
  2. How important is having good camera quality? If you take a lot of pictures and videos, or want more detailed shots, the A04s will be better. However, if you just want basic camera functionality, the Redmi A2 is fine.
  3. Do you prefer having more storage and security features? If you want more storage and more security, the A04s will be the ideal device since it offers a fingerprint scanner and also offers 128GB of storage while the Redmi A2 does not.

Scenario-Based Recommendations:

  • Scenario 1: "The Photography Enthusiast on a Budget" Go for the Samsung Galaxy A04s as it has the better camera system.
  • Scenario 2: "The Gamer Seeking Maximum Performance on a Shoestring" The Xiaomi Redmi A2 will be good as it has a higher benchmark score and it is good for budget gamers.
  • Scenario 3: "The Practical User Wanting a Reliable Daily Phone" The Samsung Galaxy A04s is a well-rounded choice, offering slightly better screen, battery and camera for everyday use.

My Choice

If I were choosing, I'd go for the Samsung Galaxy A04s. Why? As a tech journalist, I like a smoother user experience, which the 90Hz display provides. I also want to make sure I have decent camera to capture high quality pictures and videos for all my content. I also value security, so having a fingerprint scanner is important to me, since the Redmi A2 does not have it.

While the Redmi A2 has a slightly higher benchmark score, the A04s balances all the features that I would want in an ideal phone in terms of display, battery, camera and software. The addition of 15W charging, a 50MP camera, a 90Hz display, fingerprint sensor and upgrade to Android 14 on the A04s make it a far better all-around option. Ultimately, the Galaxy A04s offers a more satisfying daily experience for me, and I think most people, which is what matters at the end of the day.
