Sony is releasing a new system software update for PS5 consoles worldwide today. The update includes many user-requested features, such as 1440p HDMI video output (requires a TV or computer monitor that supports 1440p/60Hz or 1440p/60Hz and 120Hz) and gamelists, as well as social networking features.

YouTube Search via voice command (Preview)
One feature the company is offering is the ability to search for content on YouTube via Voice Command (Preview). From anywhere on the PS5, even while playing a game, you can say “Hey PlayStation, find [keyword] on YouTube.” The YouTube app will open and relevant search results will appear.
Note: Voice Command (Preview) is currently available in English for PS5 players with accounts registered in the US and UK.

New PS app features
In addition to these PS5 console updates, some new features will also be gradually rolling out to the PS app globally later this month, on iOS and Android:
Start a PS Remote Play session via the PS app
PS App users will be able to start a PS Remote Play session directly from the PS app on iOS and Android. To get started, make sure the PS app is connected to your PS5 console and your console is in Rest Mode. Then, select the “Play Using PS Remote Play” icon in a PS App game hub and the PS Remote Play app will automatically launch the game. To enjoy this feature, make sure the PS app and the PS Remote Play app are installed on your mobile or tablet device.

Similar to the PS5 feature, PS app users will be able to ask another member playing on PS5 to start a Share Screen session and then watch their friend's gameplay from the app.

The company asks users to inform the company of their feedback.
