Sony starts rolling out Android 4.3 to the Xperia Z, ZL, ZR and Tablet Z

Sony started delivering Android 4.3 updates to the shiny new Xperia Z1 and Xperia Z Ultra last week, and today it's rolling out those improvements to (slightly) older devices. The Xperia Z, ZL, ZR and Tablet Z are all getting both Google's not-quite-newest OS as well as a host of improved Sony apps, including Smart Social Camera and Walkman software. Xperia Tablet Z owners may appreciate the update most of all -- they can implement restricted profiles that give users private settings and storage. Sony hasn't said how long the upgrade will take, but don't be surprised if your Xperia gets a gift of its own this holiday.
