Samsung Ends Galaxy Z Fold 3 and Flip 3 Updates: Is It Time to Upgrade?

Samsung has ended guaranteed security updates for the Galaxy Z Fold 3 and Z Flip 3. Both devices, launched in August 2021, have now reached the end of their five-year security support period. Samsung's Knox documentation states that August 2026 marks the final month when these models will receive security updates. Samsung may release emergency fixes for severe vulnerabilities, but no routine updates are expected after this date.

As other Android devices have moved toward longer support periods, the decision to upgrade from a Fold 3 or Flip 3 becomes more crucial for owners who use their phones for sensitive information, work emails, or financial apps. While the phones will still function, app compatibility and security become increasingly uncertain after the guaranteed support window ends.

Organizations with mobile device management policies should also review whether they allow devices that no longer receive manufacturer-supported security updates.
