Welcome to the Samsung Galaxy S21 update hub. Here you’ll find the latest information on updates to the Samsung Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra. We’ll detail the current software versions for each device and alert you if there’s a new update rolling out. Samsung usually pushes out updates to the entire series, but this may vary per variant and carrier.
All the three Galaxy S21 series phones launched with Android 11 and Samsung’s One UI 3.1 skin on top. Samsung will offer three major Android OS updates to the Galaxy S21, S21 Plus, and S21 Ultra. The company also guarantees four years of security updates for all devices.
Samsung has started rolling out the June security patches for the Galaxy S21 series (h/t SamMobile). The update carries firmware version G991NKSU3AUE8, G996NKSU3AUE8, and G998NKSU3AUE8 for the Galaxy S21, Galaxy S21 Plus, and the Galaxy S21 Ultra respectively.
Currently, the security patches are only rolling out in South Korea, but you can expect them to hit your devices via an over-the-air update in the coming days.
