The Xperia Z5 came running Android 5.1.1 Lollipop, but a global roll out of Android 6.0 Marshmallow is now underway.
Contrary to previous rumors, the Xperia Z5 Marshmallow update will not include Stamina Mode, which will instead come in a later update. Some interesting features will be added, like a podcast widget and camera mode switching through swiping. The entire readout can be viewed here.
