Sony has tweaked the Status Bar and Quick Settings to be more intuitive and customisable, tailored the user interface to be more PlayStation 4-like, tweaked its entire native app portfolio to the latest versions to look and perform better, and added a custom user interface experience that enables users to pick from 280 assets to add a bit of style to their devices' theme.
