Samsung has announced a change in the update frequency for the Galaxy S21 series, which includes the Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra models.
These devices will now receive security updates on a quarterly basis, a shift from the previous monthly updates. This transition, noted on the Samsung Mobile Security website and spotted by 9to5Google, indicates that Samsung is reducing its focus on the older Galaxy S21 series, which was initially launched in January 2021.For users still holding onto a Galaxy S21 device, this change signals the start of a gradual decrease in support as the series moves away from the monthly update cycle.
Samsung had earlier committed to providing updates for up to seven years for its more recent devices, but the Galaxy S21 series is now moving toward a slower update rhythm.
After four years of monthly updates, users can expect to see updates every three months, marking a new phase in the life cycle of the Galaxy S21 series.
