Recently, Samsung has been incredibly good at sending security updates on time to its flagships, sometimes even before Google does. This month, however, things have been different, and it is only now that the June security fixes are on their way to the Galaxy S21, S21 + and S21 Ultra units sold in the US.
The delay has to do with Samsung working overtime to fix some issues with camera layers that had been widely reported just before the update was originally due to come out. While the company did not directly say that it also decided to incorporate the delay fixes in the June update, it is pretty obvious what happened.
After a few rejected rollouts internationally, the latest update finally started rolling out last week in some markets. Today, it makes it across the pond to the United States, specifically to devices sold by Verizon and Comcast’s Xfinity Mobile. We assume that the other airlines will receive the update over time.
The new build number is G99xUSQU4AUF5, and apart from the above camera layer fixes, it should also optimize portrait mode and allow you to scan QR codes from the built-in gallery app as well as provide enhanced video calling effects. Finally, overheating should be a thing of the past if one is to believe in Samsung. So all in all, this is a pretty important update that you need to install as soon as it reaches your device.
Speaking of which, the rollout is almost certainly phased, so it may take a few days (or even weeks) before every single device in the wild receives the notification. If you are impatient, go to Settings> Software update and hit Download and install while keeping your fingers crossed. Maybe you get lucky and skip the line.
