Sony kept its promise of delivering the Android 5.0.2 Lollipop on the entire Z series once again. The Japanese tech giant started rolling out the much awaited update to Xperia Z1 users yesterday. Apart from Z1, Xperia Z Ultra and Xperia Z3 Dual are also getting the update as we speak. The update is rolling out right now but the roll-out is region specific. However, if you are one of the anxious users who can’t wait to get their hands on the latest update, there’s a good news; you can manually update your phone to the latest version by using flashtool. All you need is some basic Android know-how and you’ll be all set.
