There is one particular area where all the other OEMs are generally lagging behind and no one particular OEM stands out is in the task of providing regular software updates and security patches to the devices. Some OEMs even don’t release regular updates to their year-old flagship devices, let alone the older phones. There is one particular exception though and that OEM is, Sony. Sony has been known in the android community for releasing quick updates starting with releasing the Nougat developer preview in the Sony devices along with the Nexus devices when Google released it at the I/O 2016. This trend has been continuing even till now as Sony has released the March security patch update to four of its flagship devices of 2016.
Sony has released a firmware update to its flagship devices which are Sony Xperia XZ, Sony Xperia X Performance, Sony Xperia X and Sony Xperia X Compact. The firmware updates are released seperately for the devices with two different build numbers. The firmware update with the build number 39.2.A.0.442 released for the Sony Xperia XZ and the Sony Xperia X Performance while the firmware update with the build number 34.2.A.0.333 has been released for the Sony Xperia X and the Sony Xperia X Compact.
Sony has released this security patch to all the devices in a staged rollout which means that the update will notcome to the all the devices at the same time but it will be available in batches. The security patch to this device comes with the March security update and the patch date is set to March 1, 2017. It also comes with the usual system improvements and regular bug fixes for the devices. Other than these, there is not much of a change in the new update.
To check whether your Sony device has recieved the update, you need to go to your device’s settings, then click on About Device which should be located at the end of the list, then you can check about the update by clicking on “Check for Updates” button. If the update has already arrived to your phone, make sure that your phone has more than 80% battery left or is plugged in to the charger as the update process can take time and the process should not be interrupted in between due to low battery.
