Source-derived summary

The Samsung Galaxy S21 is a series of high-end Android-based smartphones developed, marketed, and manufactured by Samsung Electronics as part of its flagship Galaxy S series. They collectively serve as the successor to the Galaxy S20 series. The first three smartphones (Galaxy S21, Galaxy S21+, Galaxy S21 Ultra) were unveiled at Samsung's Galaxy Unpacked event on January 14, 2021, while the Galaxy S21 FE was unveiled at Samsung's CES on January 4, 2022. The first three phones were released in the United States and Europe on January 29, 2021, while the Fan Edition was released globally on January 7, 2022.

The Galaxy S21 was succeeded by the Galaxy S22, which was announced on February 9, 2022.

Lineup

The line-up consists of four devices: Galaxy S21, Galaxy S21+, Galaxy S21 Ultra, and the Galaxy S21 FE. The devices would be the first time since the Galaxy S6 to remove the microSD card slot. The S21 Ultra is the first phone in the Galaxy S series to support the S Pen, albeit sold separately and with limited functionality. It is the last phone of the Galaxy S series to use the former "SM-G9xx" model number format for the flagship device which had been in use since the Galaxy S5 as Samsung started to use the new "SM-S123X" model number format for future flagships starting with the Galaxy S22.

Performance

The S21 line comprises four models with different chipsets used. International and Korean models of the S21 utilize the Exynos 2100 SoC, while the U.S., Canadian, Chinese, Taiwanese, Hong Kong and Japanese models utilize the Qualcomm Snapdragon 888.

Editorial analysis

Why this record matters

The phrase “family of Android smartphone models by Samsung Electronics” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q104537157. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2021 and 2022.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
