Sony becomes the first third party manufacturer to release the latest Android security patch for some of its premium smartphones. The manufacturer is, once again, leading the Android updates game. Sony Xperia X and X compact are now receiving the October 1, 2017, security patch level. It comes with the firmware build number 34.3.A.0.238. This comes over the previous build 34.3.A.0.228 with September security patch. Some of the Xperia X Performance users have also reported of receiving similar OTA update.

Not much is known about the OTA update as of now because the manufacturer did not release the update log (changelog). However, it most likely brings a patch towards BlueBorne vulnerability fix. The update also features Android 7.1.1 Nougat and not the latest Oreo version. Although, Sony has promised Oreo for most of the Xperia X series devices, it may take over 2-3 months to successfully deploy it.

Last month, Sony became the manufacturer to release the September 2017 security patch. It also released the latest Sony firmware source code for developers to build custom ROMS based on Android 8.0.0 Oreo.
