The Samsung Galaxy S21+ 5G in detail

How many years of updates does the Samsung Galaxy S21+ 5G get?

Released in January 2021, the Samsung Galaxy S21+ 5G received security patches until February 2026: 5 years and 1 month in total.

Among the 258 Samsung phones in our database, 197 were supported for less time and 51 for longer. The median is 4 years and 1 month.

Across all brands, the median for phones is 4 years.

The last patch came out 8 months ago.

Two schedules overlap here. New system versions stop in October 2025, security patches in February 2026. In between, the device stays on its last version but still gets fixes for security holes.

Can I keep using the Samsung Galaxy S21+ 5G?

Yes, it still works. But every security hole found after February 2026 stays open. For daily use with banking, messaging and passwords, a supported device is the safer choice. As a spare without your main accounts (alarm clock, music player, camera), it's still useful. Do a factory reset before you give it away or recycle it.
