2. Key Insights

  • Nokia G21:

    • Strengths: More camera lenses giving it more shooting versatility. Slightly better benchmark performance and includes the power brick in the box.
    • Competitive Advantage: The triple camera setup (including macro and depth sensors), which might appeal to those who like to take varied photos, and the 10W charger in the box.
    • Trade-offs: Older version of Android, less base storage, and less fast charging.
  • ZTE Blade A75 4G:

    • Strengths: Newer Android version, more base storage capacity, and slightly faster charging speed.
    • Competitive Advantage: The additional storage, the newer version of Android, faster charging, and the presence of a gyroscope sensor.
    • Trade-offs: Lacks dedicated macro and depth cameras and the power brick is not in the box.

3. User Profiles and Recommendations

  • Nokia G21:

    • Best Suited For: Budget-conscious users who value camera flexibility and might not need tons of storage, and don't mind older versions of Android. Users who value having everything they need (charging brick) in the box.
    • Use Cases: Casual photography, everyday social media, general use, and video sharing.
  • ZTE Blade A75 4G:

    • Best Suited For: Users who prioritize storage, multitasking, and the latest Android version.
    • Use Cases: Daily communication, media consumption, gaming, and running multiple apps simultaneously.

4. Buying Decision Framework

Here are three practical questions to help you choose:

  1. How much storage do I really need?

    • If you need a lot of space for media and files, the ZTE Blade A75 4G, with its base 256GB option is a clear winner. If storage is not as important, the Nokia G21's 128GB option should be enough.
  2. Is having a dedicated macro or depth sensor essential for my photos?

    • If you want to experiment with close-ups and portraits, the Nokia G21 has a dedicated lens for that. If you only use the main lens or your phone for selfies, the ZTE Blade A75 4G is the one to look at.
  3. How important is having the latest Android software version?

    • If you want the latest software features and security, the ZTE Blade A75 4G with Android 13 is the better pick. If you don't mind an older operating system, the Nokia G21 is a safe bet as well with a possible future update to android 13.

Scenario-Based Recommendations:

  • Budget Photographer: The Nokia G21’s triple camera setup gives you more options for varied shots.
  • Power User: The ZTE Blade A75 4G with its faster charging and extra RAM is ideal for more demanding use.
  • Casual User: Either phone will do well, but consider how important the different features are for you.

My Choice

If I had to choose, I'd go with the ZTE Blade A75 4G. Here's why:

  • Storage: The base 256GB storage capacity is a game-changer for me. I like to keep a lot of media on my phone, and having that much space is incredibly convenient.
  • Newer Android Version: I prefer having the latest software, not just for features, but also for better security and app compatibility.
  • Gyroscope: I dabble in gaming, and the gyroscope sensor on the ZTE Blade A75 4G adds another layer of functionality for supported apps.
  • Faster Charging: While not a huge difference, having a faster charging speed is handy for quick top-ups. I am also fine with buying my own charging brick as I have several already.

While the Nokia G21 is a solid phone, the ZTE Blade A75 4G's combination of more storage, updated software, and a gyroscope sensor makes it a better fit for my use case. The difference in camera capabilities is small and the slightly faster charging and more ram in ZTE A75 are more important for me personally.

Both phones offer great value for the price, so the "best" choice really depends on your priorities. I hope this breakdown helps you make the right decision for your specific needs!
