Ratings

The Samsung Galaxy S21 5G, released in January 2021, and the Samsung Galaxy S23 FE, launched in October 2023, are both Android smartphones from Samsung's popular Galaxy S series. While they share the same operating system, key differences lie in their release timelines, software support longevity, and advancements in camera technology and overall performance. This comparison aims to highlight these distinctions to help users make an informed decision.

Scores

Durability

The practical lifespan of a smartphone is significantly influenced by its release date and the manufacturer's software support policy.

  • Software Support: The Galaxy S21 5G, having been released in January 2021, has received its promised four major Android operating system updates and is now at the end of its five-year security update cycle as of early 2026. This means it will no longer receive new Android versions or regular security patches. In contrast, the Galaxy S23 FE, launched in October 2023, is set to receive major OS updates until approximately October 2027 and security updates until October 2028, offering a considerably longer period of official software support.
  • Build Materials: The Galaxy S21 5G features a Gorilla Glass Victus front for display protection, an aluminum frame, and a plastic back. The Galaxy S23 FE, a more recent model, utilizes Gorilla Glass 5 for both its front and back panels, coupled with an aluminum frame, providing a more uniform feel.
  • Durability Rating: Both devices carry an IP68 rating, indicating robust resistance to dust and water. This means they can withstand submersion in up to 1.5 meters of fresh water for up to 30 minutes, offering peace of mind against accidental spills and splashes.

Performance

Performance is a critical aspect for daily usage, affecting everything from app responsiveness to gaming and multitasking capabilities.

  • Processing Power: The Galaxy S21 5G is equipped with a high-end processor from early 2021, which delivers smooth performance for everyday applications, web browsing, and moderate gaming. It handles multitasking efficiently, ensuring a responsive user experience. The Galaxy S23 FE, featuring a flagship-tier processor from early 2022, offers enhanced processing power. This translates to faster app loading times, smoother transitions, and more capable handling of graphically intensive games and demanding productivity applications.
  • Multitasking and Storage: Both smartphones typically come with 8GB of RAM, which is sufficient for managing multiple applications simultaneously without significant slowdowns. For internal storage, both offer 128GB and 256GB options. The 256GB and higher variants of the Galaxy S23 FE benefit from a newer, faster storage technology (UFS 4.0) compared to the S21 5G, which can contribute to quicker data access and app performance.
  • Overall Responsiveness: While the Galaxy S21 5G remains a capable device, the Galaxy S23 FE generally provides a snappier and more fluid experience, particularly in scenarios involving heavy usage or the latest applications, due to its more recent internal components.

When evaluating the Samsung Galaxy S21 5G and the Galaxy S23 FE, user priorities regarding software longevity, performance, and physical design will likely guide the decision.

The Galaxy S21 5G is often praised by users for its more compact size and still-capable performance for everyday tasks, even several years after its release. However, a frequent criticism, especially as of early 2026, is its nearing end-of-life for software and security updates, which can be a significant concern for users prioritizing long-term support. Some users also noted its plastic back as a less premium feel compared to other flagship devices of its era.

The Galaxy S23 FE, on the other hand, receives positive feedback for its vibrant, slightly larger display, its more modern camera system with true optical zoom, and its robust performance that handles demanding applications smoothly. Common criticisms include its noticeably larger and heavier build compared to the S21 5G, and some users have pointed out that its processor, while powerful, is not the absolute latest generation available at its launch. The slightly thicker bezels around the screen have also been mentioned.

Users prioritizing a compact form factor, a device that still performs well for general use, and who are comfortable with a device at the end of its software support cycle, might find the Galaxy S21 5G suitable. Conversely, users seeking extended software longevity, a larger and brighter display, and a more advanced camera system, who do not mind a slightly larger and heavier device, may lean towards the Galaxy S23 FE. Both models are available as quality-assured refurbished options, providing an eco-friendly alternative for consumers.
