In October 2015, Sony announced the list of devices eligible for Android Marshmallow and within days the company rolled out the concept software to select Xperia Z series inciting excitement among fans that the public version will be deployed really soon, but months have passed by with no word on when actually it will commence.

Now, a new report has surfaced online that states Android Marshmallow release has been delayed indefinitely for select Sony devices.

Xperia Blog citing Australia's popular network carrier Telstra website, has claimed that the Android M release has been put on hold temporarily for Xperia Z4 Tablet.

"The update has been delayed & pending Sony to revise submission date," reads the Telstra software update support page of Xperia Z4 Tablet.

This means Sony might have found bugs in the test software and probably take additional time to fix them.Once convinced that there are no issues, Sony will send the ETA (Estimated Time of Arrival) of software to partner carriers. There is no word on whether the company has faced similar glitches in the firmware related to other Z4 and Z3 series devices. Watch this space for more updates.

For the uninitiated, Android Marshmallow is confirmed to be released to Sony Xperia Z5, Xperia Z5 Compact, Xperia Z5 Premium, Xperia Z4 Tablet, Xperia Z4 (aka 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 models.
