At Sony’s CES 2015 press conference last night, Sony’s Chief Operating Officer Michael Fasulo announced that the Xperia Z3 lineup will start receiving Android 5.0 Lollipop as soon as next month.
Fasulo didn’t offer any specific dates, just that they are set to begin rollouts starting in February. This follows Sony’s timeline they set in October, promising that they would release Lollipop for their Z3 lineup 90 days within the release from Google.
