Samsung is ending support for the Galaxy S21 series, marking a significant shift in its update strategy. The Galaxy S21, S21 Plus, and S21 Ultra are no longer included in the company's regular security update schedules, indicating the end of routine updates. This decision aligns with Samsung's typical seven-year update promise, which only applies to the Galaxy S24 series. The Galaxy S22 series, on the other hand, has transitioned from monthly to quarterly security updates as its support life nears its end. These changes highlight Samsung's evolving approach to software support for its flagship devices, leaving older models like the S21 series behind. The Galaxy S21 FE is also now on the quarterly update list, further emphasizing the transition. For Galaxy S21 owners, the lack of ongoing security updates may prompt an upgrade, but it's worth considering alternative options like the S25 FE. The article invites readers to share their thoughts on Samsung's Galaxy S strategy in the comments, sparking discussions on the implications of these changes.
