Samsung has modified the security update schedule for the Galaxy S21 series, with models now set to receive Google and manufacturer’s fixes on a quarterly basis instead of monthly updates. This shift is in line with the phone line’s launch in January 2021, which has been receiving monthly updates for four years.
Galaxy S21 series no longer getting monthly updates
Galaxy S21, S21 Plus, and S21 Ultra will now receive updated security packages every three months for at least another year due to the revised upgrade schedule.
The Galaxy S21 FE will still get monthly updates since it was released almost a year later than the usual models.
Samsung launched the January 2025 security update for the Galaxy S21 series before transitioning to the new calendar, with the possibility of additional monthly updates before the schedule change.
The three models will soon get their final significant update, One UI 7.0 on Android 15. The Galaxy S21 FE will receive its last major update with Android 16, as it was launched with Android 12, while the others came with Android 11.
Samsung is getting ready to end support for older devices like Galaxy Z Fold 2, A21s, A02s, A12, and W21 5G by scheduling the Galaxy S21 line in the quarterly calendar.
