The Galaxy S21 FE 5G gets its share of software updates, including the Android 14-One UI 6. It will even make it to the list for the next Android 15 (One UI 7) update. The fate of the Galaxy S9, on the other hand, is that it has already expired on the software support lifecycle, and updates have stopped coming in with Android 10.
Considering the advancements in hardware, display technologies, cameral versatility, battery capacity, and being under ongoing software support, the S21 FE 5G will be deemed the better future-proof and capable device for 2025. Its features match user expectations and technologic standards. Hence, one would recommend it over the Galaxy S9.
