Second February patch rolling out now

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.

If you have not yet purchased a Galaxy S21, check out the deals below. Scroll beyond the box below for historical update information for the Galaxy S21 series.

Samsung Galaxy S21

The vanilla Galaxy S21 is the smallest and most affordable of the three Samsung Galaxy S21 series phones. You do get a palm-friendly 6.2-inch display and basically the same specs as the Galaxy S21 Plus. You do need to sacrifice battery capacity by a bit, though, as the Galaxy S21 only has a 4,000mAh cell. Your wallet will be happy, however, because the starting price of the phone is just $799.

Samsung Galaxy S21, S21 Plus, and S21 Ultra updates

  • Current stable version: Android 11
  • When will the Galaxy S21, S21 Plus, and S21 Ultra get Android 12? December 2021 (Estimated)

Samsung launched the Galaxy S21 series on January 14, 2021. Pre-orders opened on the same day, while the devices were available in stores on January 29, 2021, across the US and Europe. All three phones launched with Android 11 out of the box with Samsung’s One UI 3.1 skin on top.

Samsung has been swift to push updates to its devices of late, and that trend continues with the Galaxy S21 series.

Well before the phone landed in consumers’ hands, Samsung rolled out two updates. Per SamMobile, firmware versions G991BXXU1AUAB, G996BXXU1AUAB, and G998BXXU1AUAC improved camera and device performance and weighed in at around 278MB.

In early February, the Galaxy S21 series received the February 2021 Android security patch in its first post-launch update. However, users on Reddit and Samsung’s forums discovered the update may have caused battery drain issues on some devices. Those experiencing issues noted that switching the phone to airplane mode halted the drain, which suggested mobile network connectivity was the culprit.

A second update, pushed to users on February 14, seemingly plugged the drain. Per PhoneArena, the update brought firmware version G99xBXXU1AUB6 and weighed in just under 260MB. Per the changelog, it brought device stability improvements, additional performance buffs, and enhanced features.


Below are the current stable versions of each device in the Galaxy S21 family.
