Samsung's Smart Switch app now lets Windows Phone 8.1 users migrate to a Galaxy device
In addition, the latest update includes extended support for users switching from iOS 9 – namely, the ability to import iWork-generated documents to their new Galaxy phone. The app also ought to be faster and more stable now.
Smart Switch supports wired or wireless transfers, although the options are varied depending on the device and OS your switching from. The app is pre-loaded on Galaxy S7, S7 edge, and Note 7 smartphones and can be accessed via the Settings menu. Users of other devices can download the app, whose logo is oddly similar to that of Skype, right from the Google Play store (link).
