Sony Mobile has started to roll out the new firmware with the build number 28.0.A.8.272 for Xperia Z3 Plus and Xperia Z3 Plus Dual. New firmware is currently available in Taiwan and Hong Kong. So this will replace the previous build 28.0.A.8.266 from the new build 28.0.A.8.272. We can guess this should be the last update before the Android 6.0 Marshmallow update. Xperia Z3 Plus will get the Marshmallow after Xperia Z5 Series. Stay tuned with XperiBlog for more news.
