Shortly after its PlayStation Experience 2015 event in San Francisco this weekend, Sony has released a brand new app called PlayStation Messages, which allows PlayStation 4 owners to chat with their friends on the go. While the standard PlayStation app had built-in messaging functionality, it's been split into its own app like how Facebook did with Facebook Messenger.
The app allows PlayStation Network users to send their friends text, voice and picture messages in addition to stickers of PlayStation game characters like Knack and Uncharted's Nathan Drake. The app also allows for group messaging.
The standard PlayStation app was also updated today with the ability to follow verified users and the removal of the messaging functionality.
