Sony usually takes time to roll out software update to its devices but it seems some of them from the Xperia line will receive Google's latest firmware Android 6.0 Marshmallow as early as December 2015, contradicting earlier reports that it might arrive next year.

The Japanese technology giant is yet to announce Android 6.0 Marshmallow update schedule for its devices but a report by Android Headlines has claimed that the firmware is expected to come to some Xperia lines before the end of this year and for the rest, by early 2016.

It was earlier reported that the software might come to Sony devices latest by January 2016.

The report went on to claim that some Sony devices, including Xperia Z3+, Xperia Z4 Tablet, Xperia M4 Aqua, Xperia C4, Xperia C5 Ultra and Xperia M5, will skip Android 5.1.1 Lollipop update and get Android 6.0 Marshmallow directly.

Sony has revealed the list of devices that will receive the firmware update but is yet to announce update schedule. So, nothing is confirmed as of now and it won't come as a surprise it takes longer than expected.

However, it is confirmed that Sony will roll out the new firmware update to over a dozen Sony devices, including Xperia Z5 and Xperia Z5 Compact.

The company's official blog has revealed that 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, Xperia C4, Xperia Z5 Premium, Xperia Z5 and Xperia Z5 Compact will get the Android 6.0 Marshmallow.
