After a lengthy beta program for the Xperia Z2 and Z3, Sony has announced they have begun rolling out the Android Marshmallow update to the wider lineup of those devices, including those that were not in the beta program. The update is firmware build 23.5.A.0.570 for those keeping score and brings these devices up to Marshmallow 6.0.1. Owners of the Z2 or Z3 should start seeing the update come to them via an OTA update in the coming days.
The update is specific to various builds of the Xperia Z2 and Z3 so you will want to check your specific device to see if it is included. For the Z3, the D6502 model is getting the update while for the
Sony Xperia Z3
Z3, the D6646 and D6653 are receiving it. The Z3 Dual D6633 is also seeing the update as is the Z3 Compact D5833. Finally, for the Z2 tablet, the SGP511, SGP512 and SGP521 are all receiving the update. You can check which model you have by going to Settings>About Phone on your Xperia.
While Sony hasn’t been the fastest when it comes to getting Android Marshmallow out, they have done a good job of covering a large portion of their device lineup with the update. Perhaps the silver lining in the long wait is that users of the Xperia lineup will jump to 6.0.1 with the March security update instead of being upgraded just to 6.0.
You can check for the update by going to Settings>About Phone>Software Update but it could take several days before it reaches everyone.
