S21 Series Receives Final Security Update

JAMES4578 — Mon, 26 Jan 2026 17:31:46 GMT

The January security update is rolling out to the S21 series, this fixes 55 security flaws and 1 is critical compared to 28 severe. It has started rolling out on South Korea and should reach other markets soon. This though looks like being the last security update as the promised support ends this month.

When support ends vulnerability increases and users who only have this Device may wish to have a look at more modern Devices. of course not too long till the S26 series launches.

certainly the S21 Ultra standouts in Samsung's history I would say though.
