    • Ideal For: Users seeking an affordable device with the newest Android software, a good CPU and GPU, and a big screen.
    • Use Cases: Media consumption, gaming, and users that need a newer phone.

4. Buying Decision Framework

Here are three questions to consider when deciding between these two phones:

  1. How important is screen visibility in bright environments to you? The S21 FE's 1300 nits of brightness makes it far superior for outdoor use.
  2. Are camera quality, extra features and a comprehensive sensor suite essential? The S21 FE has a superior camera system with more features, wireless charging, reverse charging and extra sensors.
  3. How important is getting the newest software and potentially superior performance? The realme 8 has the newest Android system, and a very powerful CPU and GPU that may surpass the S21 FE, although it has no data to support it.

Scenario-Based Recommendations:

  • Budget-Conscious User: The realme 8 is a budget choice for the newest software, but with the lack of specifications it may not be the best purchase. The S21 FE is a far superior phone, but the realme 8 may provide better value depending on its price.
  • Power User: The S21 FE, with its many features, very bright screen, good performance and versatility is the best choice.
  • Casual User: The S21 FE is a better option, with a good camera and display, unless the user needs the newest Android software and wants to gamble on the realme 8 and its missing specifications.

Final Choice

If I were choosing between these two, the Samsung Galaxy S21 FE 5G would be my pick. The realme 8 is a blank slate, and I can’t recommend it without specification data to back up its claims. The S21 FE, despite being a bit older, offers a more polished, feature-rich experience. The Snapdragon 888 is still incredibly capable, the camera system is top-notch, and the 1300 nits display brightness for outdoor use is a necessity for me. Plus, features like wireless charging, reverse wireless charging, and a fully featured sensor suite make it incredibly versatile and suitable for all my daily needs.

The realme 8's lack of information, missing features, questionable specs, and significantly lower screen brightness puts it behind the S21 FE, which even being a little bit older, is a more complete, capable and superior phone.
