While some Nexus handsets are already seeing Android Nougat – the latest OS from Google – and it’s even speculated that many non-Nexus devices will be getting it before the end of this year, it appears that other manufactures are still struggling with implementing the last OS from Google.

One of those manufacturers is Sony and it has announced recently that it will be rolling out Android Marshmallow firmware for the Xperia C4 and the Xperia C4 Dual. As a result, the build version for Xperia C4 will turn to 27.3.A.0.112 and the one for the C4 Dual will turn to 27.3.B.0.122.

Along with the OS firmware, the two devices will also get many new features like additional functions and an overall improved user experience with Android 6.0 Marshmallow.

According to XperiaBlog, the firmware update is available at the moment only for the E5303 and E5306 models of Xperia C4 and the E5333 and E5343 models of Xperia C4 Dual. However, it will soon become available for the remaining models: E5353 and E5363.

At the same time, the Android Marshmallow firmware is also being seeded for Xperia C5 Ultra Dual, model E5533. It is also scheduled to become available very soon to the other models of the device.

If you own one of these devices, you should receive a notification that lets you know that the update is available. If you have received it just go through the usual steps of downloading and installing something on the device, while paying extra attention to all of the prompts that guide you through the installation process.

If you haven’t received the notification, you can manually look for it in Settings>> About Phone>> Software Update. However, keep in mind that not all devices will receive the update now because this aspect depends on your country and local carriers.
