At Microsoft Build, Microsoft announced a new app called ‘Your Phone’ which can be used on iPhone & Android. This will allow you to do things like send text messages, access photos and view mobile notifications right from your Windows 10 PC!
The different features that are available will depend on the OS that you are phone is running, with Android phones being able to mirror a larger range of features than iOS.
This app is currently in beta and available in the Windows Insider Programmer. The app will be released (most likely in the next version of Windows 10) in Autumn.
