Can I dial and make a phone call using the TV remote when a smartphone is connected to the TV using Mobile High-Definition Link (MHL) cable?
Navigation through an Android® device's interface using the TV's remote control while both devices are connected using a Mobile High-Definition Link™ (MHL) cable depends on the capability of the Android device. For Xperia® mobile devices, you can enter a phone number and make a phone call using the arrow (navigation) buttons and the Enter button.
