Galaxy S21 May 2021 security update improves Camera and Quick Share

Samsung’s been rolling out the April 2021 security patch to countless Galaxy devices for a few weeks now, but it’s time for the company to switch gears, introduce a newer security update, and repeat the process of bringing it to as many phones and tablets as possible within the next few weeks.

The May 2021 security patch just got released and it’s now available for none other than the Galaxy S21 flagship series. As always though, the update is available in a limited number of markets at first, and it should gradually expand to include more regions. The May 2021 security patch has debuted on the Galaxy S21 series in Europe and the update carries firmware version G99xBXXU3AUDA.

A hefty 1.2GB firmware update with extra enhancements

The Galaxy S21 series may be the first to receive the May 2021 security patch, but you can be certain that it won’t be the last. The fun has only begun, and as to which Galaxy device will be updated next, well, it’s anyone’s guess. It could very well be another flagship phone or a budget-oriented device from the Galaxy A / M series.

Whatever the case maybe, Samsung hasn’t detailed the May 2021 security patch but it has released a changelog for the whole update, and the package contains more than just the latest security patch.

Galaxy S21 owners in Europe are looking at a 1.2GB download, and the changelog mentions improvements to both the Camera and Quick Share. You should be able to download the new firmware from the phone’s Settings app, or you can refer to our firmware archive, search for your device and model number, and download the latest update to install manually on your phone.
