Sony has released a new dedicated messaging app on Android and iOS.
PlayStation Messages is the newest app from Sony. It takes what the company believes is the most used feature of the PlayStation App, messaging, and dedicates a new app to it.
The app works similarly to the various other messaging apps, only you'll be connecting with your PSN buddies.
It displays your full friends list, and you can sort it by status or alphabetically. Groups are another thing that you can view in the app. The ones you follow will appear there, letting you message several people at once, you can even leave voice messages, stickers, and attachments.
