Xperia XZ1, XZ1 Compact Getting October 2017 Security Patch

The October 2017 security update for Android is now beginning to land on the Sony Xperia XZ1 and Xperia XZ1 Compact, bumping their build number from 47.1.A.2.324 to 47.1.A.2.374. The over-the-air (OTA) update includes the security patch level dated October 5th that addresses various security vulnerabilities that affect Android devices, with the most critical of these security issues being the vulnerability spotted in the Android media framework that could possibly allow an attacker to remotely execute arbitrary code with unauthorized privileged access.

The rollout marks the launch of the first security update for the new Sony Xperia devices since the release of the Xperia XZ1 last month and of the Xperia XZ1 Compact earlier this month. As a quick recap, the Xperia XZ1 sports a 5.2-inch HDR Triluminos IPS LCD display with a resolution of 1080 x 1920 pixels, while the Xperia XZ1 Compact includes a 4.6-inch screen with the same display technology and a resolution of 720 x 1280 pixels. It is worth pointing out that the security update is hitting the Xperia XZ1 and Xperia XZ1 Compact just two weeks after Google published the latest set of fixes for its mobile OS. It also seems that the update has started to land on some Xperia XZ1 and Xperia XZ1 Compact devices no later than Friday, October 13th, meaning that the software package should already be available to a significant number of users. Based on the screenshot provided below, it also appears that the software package has been released in the Netherlands and possibly some neighboring countries.

As is usually the case with most security updates, the October 2017 patch is expected to debut a host of fixes for a variety of security issues and vulnerabilities that were recently detected in Sony’s latest smartphones. Since this is an OTA update, make sure to download the security patch over a Wi-Fi connection and have your phone charged to at least 50 percent before starting the installation. If you have not received the software package yet, you can manually check for the update by going to your device's Settings app, navigate to the "System" section and then tap the "System updates" option on the following screen.
