With the Sony app Smart Connect, you are able to decide what happens when you attach a device or accessory to your smartphone. The app reacts differently depending on the device and the time of day. The devices or accessories that are compatible are charger cables, headphones and headsets, while other kinds can be added with the +/-button too. You are able to set it up so that when you plug in your headphones, the Walkman app will start automatically. You can also set it up to switch to silent mode when it is between 10 PM and 7 AM and is plugged into the charger.
