New firmware update rolls out to the Galaxy Z Fold 2 to improve security

The October 2020 security patch is now reaching Samsung’s foldable phones, or at least the company’s latest device in the foldable series. After improving the security level of various candy bar smartphones including the Galaxy A50/A51, the Galaxy S10/S20, and the Galaxy Note 10/Note 20, Samsung is now releasing a new firmware update for the Galaxy Z Fold 2 that includes the October 2020 security patch.

The latest update for the Galaxy Z Fold 2 carries firmware version F916UXXS1BTJ1 and it’s rolling out in dozens of countries across multiple continents. There are too many to count but you can refer to our firmware archive and verify if the latest firmware update is available in your country. In addition, the latest firmware update is bringing the October 2020 security patch to the Galaxy Z Fold 2 on Sprint’s network in the USA. This firmware version is labeled as F916USQS1ATJ1.

Addressing Secure Folder vulnerabilities

Samsung doesn’t seem to be bringing any new meaningful changes to the Galaxy Z Fold 2 user experience with the latest firmware update, but the package does bring the October 2020 security patch which is fairly important.

The October patch fixes 21 vulnerabilities found in Samsung’s software, and one of the bugs can theoretically be exploited to give malicious parties access to the user’s Secure Folder contents. Of course, exploiting this vulnerability is not as easy as it sounds but it is good to know that Samsung has addressed it, so even if the latest firmware update doesn’t include major additions, it’s still a welcomed release and Galaxy Z Fold 2 owners should be getting it as soon as they are able to.

As usual, you can download the firmware by opening Settings, accessing Software updates and tapping Download and install on your phone. You can also refer to our firmware archive, search for the Galaxy Z Fold 2, download the latest update from there and install it on your phone using a Windows PC.
