At the end of April 2021, the Galaxy S21 became Samsung’s first batch of smartphone products to obtain security patches in certain regions such as Europe in May 2021. Later, this firmware update covered more countries, including Asia, the United States, and so on.
Unexpectedly, the South Korean giant made another software update for the Galaxy S21 and Galaxy S20 product lines, which also includes the same changelog and the May 2021 security patch. However, the company further updated the details of this patch and confirmed that it has fixed a new vulnerability in Qualcomm’s 5G modem.
In recent developments, Samsung is rolling out new firmware updates for the latest Galaxy S21, S21+, and S21 Ultra phones in India. Just like the European OTA, this update provides fixes for the recently discovered Qualcomm 5G modem vulnerabilities, as well as fixes for Samsung’s 23 CVEs.
Users can identify this update by the version number: Galaxy S21 Ultra, Galaxy S21+, and Galaxy S21 G998BXXU3AUE1, G996BXXU3AUE1, and G991BXXU3AUE1 respectively. The update log shows that this update brings system stability improvements and functional enhancements.
Prior to this, the Galaxy S21 had a software update on May 1, 2021, with major improvements to the camera and quick sharing functions. At the same time, Samsung provides a new camera feature called “dual recording” for older Galaxy S20 and Galaxy Note 20 smartphones.
