Owners of Sony's high-end devices like Xperia Z3, Xperia Z4, Xperia Z5, Xperia C5 Ultra and Xperia M5 are eagerly waiting for Google's latest operating system, Android 6.0 Marshmallow, but it hasn't happened yet. But latest developments indicate the firmware might come to Sony devices very soon.

Android 6.0 Marshmallow came to LG Nexus 5X and Huawei Nexus 6P devices before it was rolled out to Google Nexus devices. Several smartphone-makers, including LG, HTC and Motorola, have started pushing out the firmware to their devices, so it natural for Sony fans to expect it.

Going by the pace at which Sony is working to bring the firmware to its devices, it seems the update will come to some devices in the month of January itself, though some handsets may have to wait a little longer.

The Japanese electronics giant has already rolled out Android 6.0 Marshmallow beta to Xperia Z3 Compact devices. Android Marshmallow Concept beta programme has been made available to the Sony Xperia Z3 and Xperia Z3 Compact devices, giving a clear hint that the software will soon come to Sony devices.

Moreover, it's been reported that the new firmware bound for Sony Xperia Z5 and Xperia Z4 in Japan has been certified by the Wi-Fi Alliance, a process that is needed to for OTA (over-the-air) software update.

Sony had earlier revealed that over a dozen of devices would receive the Android 6.0 Marshmallow update. Here is list of Sony handsets that are eligible to get the new firmware: Xperia Z5, Xperia Z5 Compact, Xperia Z5 Premium, Xperia Z4 Tablet, Xperia Z3+, Xperia Z3, Xperia Z3 Compact, Xperia Z3 Tablet Compact, Xperia Z2, Xperia Z2 Tablet, Xperia M5, Xperia C5 Ultra, Xperia M4 Aqua and Xperia C4.
