End of Support for Galaxy S21 Series

The Galaxy S21, S21+, and S21 Ultra launched in January 2021 with a promise of four major Android OS upgrades and five years of security patches. After five years, those updates have ended, and the devices will no longer receive any security or OS updates.

What This Means for Users

Without ongoing security patches, the devices become vulnerable to emerging threats and may experience compatibility issues with newer apps. If you own one of these three models, now is an optimal time to consider a replacement.

Recommended Upgrade: Galaxy S25 Series

The upcoming Galaxy S25, S25+, and S25 Ultra are the natural successors within Samsung’s flagship lineup. They are expected to launch soon, and you can anticipate:

  • Hefty discounts in the weeks following the launch of their next generation
  • Continued support with seven years of security updates and seven major Android OS upgrades
