    The firmware comes at a size of 330MB and with build number A720FXXU2BQK2. The update brings the latest November security patch and fixes for 61 Android security issues. As per the reports, the update also removes bugs specific to Samsung's UI.

    However, the most important thing this update brings is a security patch for the KRACK vulnerability.

    Just to recall KRACK (Key Reinstallation AttaCK) is a vulnerability that targets the third step in the four-way authentication handshake that is performed when your Wi-Fi client device tries to connect to a protected Wi-Fi network. The encryption key can be resent several times during the third step, and then the attackers can collect and replay the retransmissions in specific ways and break the Wi-Fi security encryption.

    In any case, this new update will be replacing the previous October security patch. The monthly patches offer protection against latest security threats that can make Android devices vulnerable to security malfunction.


    The update is basically being rolled out as an OTA update so it might take time to reach all the devices globally. OTA updates are generally rolled out in phases. Meanwhile, the users of the Galaxy A7 (2017) smartphones can check for notifications of the update. They can also check for the same manually by heading to Settings>About Device >Download Updates Manually.
