2. Key Insights

Nokia C31

  • Strengths: Marginally larger display and dedicated macro and depth cameras.
  • Competitive Advantages: May appeal to users who value a slightly larger display or creative photography tools.
  • Trade-Offs: Uses an older, less powerful chipset, slower charging speeds, and older Android version. Lacks a gyro sensor which could be useful in some applications.
  • Limitations: No expandable storage and less RAM and storage capacity compared to the ZTE. Older version of Bluetooth and less advanced WiFi.

ZTE Blade A75 4G

  • Strengths: Significantly better performance due to its more powerful chipset, faster charging, smoother 90Hz refresh rate, a higher-resolution main camera, and a newer operating system.
  • Competitive Advantages: Ideal for users who want a smoother, more responsive experience, faster charging, and better overall performance.
  • Trade-Offs: Lacks dedicated macro and depth cameras and a slightly smaller display.
  • Limitations: No expandable storage.

3. User Profiles and Recommendations

  • Nokia C31: Best suited for users who need a basic phone for everyday tasks, media consumption, and simple photography, and prioritize the slightly larger screen. This phone would not be suitable for gaming.
  • ZTE Blade A75 4G: Ideal for users who want a smoother experience, better performance, faster charging, and higher-resolution photos. Great for users who do more multi-tasking or use larger apps. This phone is suitable for most types of gaming.

4. Buying Decision Framework

Here are three questions to guide your choice:

  1. Do you value performance and speed over camera features? If yes, the ZTE is a much better option.
  2. Are you okay with a slightly smaller screen for a more compact phone with better charging speeds? If yes, the ZTE is preferable.
  3. Is expandable storage important to you? If yes, neither phone is a good fit and you will need to look at another model.

Scenario-Based Recommendations:

  • Budget User: If you want the most bang for your buck the ZTE is the clear winner here, offering a much better chipset, a better display and a better camera, at the cost of the depth and macro lens.
  • Multimedia Enthusiast: If you mainly consume content, the ZTE with its smoother screen will be a better option.
  • Photography Enthusiast: While the Nokia has dedicated macro and depth cameras, the ZTE will give you better clarity and performance due to the higher resolution sensor. The lack of depth will not be as significant to most users, as the software will allow you to create bokeh.

Final Thoughts:

The ZTE Blade A75 4G emerges as the stronger contender. It offers a superior chipset, faster charging, a smoother 90Hz display, and a better camera, making it the ideal choice for anyone seeking a more fluid and capable mobile experience.

Which one would I choose? I'd go with the ZTE Blade A75 4G. Here's why:

  • Performance Matters: As a tech journalist, I need a device that can handle multitasking and research, and the ZTE's Unisoc T606 chipset and Mali-G57 GPU are significantly more capable than the Nokia's setup.
  • Smoother Experience: The 90Hz refresh rate is a noticeable upgrade for everyday use and feels far better than the Nokia's 60hz, making the whole experience more fluid.
  • Faster Charging: I'm constantly on the go, and the 22.5W fast charging is a huge advantage for quickly topping off the battery.
  • Better Camera: While I like the versatility of additional lenses on the Nokia, the ZTE's 50MP sensor is going to give me sharper photos.
  • Newer OS: Finally, the newer OS ensures a longer software support window which is good for the long term.

The ZTE Blade A75 4G simply delivers a more well-rounded experience for most users. It’s an easy choice for someone who cares about performance and daily functionality.
