Samsung has ended support for its Galaxy S21 series, confirming through its official update page that the January 2021-released smartphones have reached the end of their update cycle. This means the Galaxy S21, S21+, and S21 Ultra will no longer receive periodic security updates or new operating system versions.
The decision coincides with the removal of the S21 family from Samsung’s list of actively supported devices on its website. Samsung is fulfilling its commitment made at launch: four years of major Android updates and five years of security patches.
What Does “End of Support” Actually Indicate?
Reaching the end of support doesn’t mean the device will stop functioning. The phone will continue to operate normally, but it will no longer receive quarterly security updates or system improvements. Over time, this can lead to increased exposure to vulnerabilities that will no longer be officially addressed. As mobile security threats evolve, maintaining updated software is increasingly critical for protecting user data.
A Shift in Strategy for Newer Models
Until now, Samsung had maintained a policy of five years of security corrections for this generation. However, the company has extended this timeframe on its more recent models. New Galaxy S phones now offer up to seven years of Android and security updates, meaning devices like the Galaxy S25 series will be covered until 2032.

From this point forward, users continuing to use a Galaxy S21 should be aware of the following:
- No new versions of the system or One UI layer will be published.
- Periodic security patches will no longer be received.
- Compatibility with future applications and services may decrease over time.
Security and Privacy Risks
Technology specialists say the absence of security patches poses a real risk. These updates not only fix technical errors but also protect sensitive data such as passwords, banking information, or personal credentials. The increasing sophistication of cyberattacks underscores the importance of timely security updates.
While the Galaxy S21’s hardware remains sufficient for everyday tasks like social media or multimedia consumption, the device’s security will increasingly depend on user behavior: avoiding applications from unofficial sources, exercising extreme caution on public Wi-Fi networks, and maintaining secure digital habits.

Samsung recommends that those who want to continue receiving security updates and new features in the long term consider upgrading to a newer model with the expanded support plan. The “end of life” for the Galaxy S21 is not immediate, but it does mark a key point for millions of users who will have to decide whether to continue using it with greater precautions or opt for a device with guaranteed support for more years.
