Mobile Services Limitations on Windows Store Platform
Telephony Service and Messaging Service
Windows Store currently not support cellular call and cellular messaging
Mail service will launch default mail client, but cannot insert attachment automatically, so user still need to insert attachment if they want to.
Windows Store apps use charm to share text, image, etc. In social service we can set automatically what social media we want to use, but in Windows store, it automatically load every apps that related and show them to user. So user can choose themselves what tipe of share options that they want to use. And as social service accept multiple image to share at once, Windows Store charm only allow one of them for now.
Camera service will launch camera or web cam that installed in the device, but settings like flash, etc, need to set manualy.
