The PS4 continues to get new features, but it hasn’t shed some of the older ones that get in your way. If you’re sick of seeing notifications for events you don’t care about, here are a few settings you can tweak on your PS4.
On the main screen of your system, select Settings on the upper row of icons. In the Notifications entry, you can see various events — all of them trigger a notification to appear in the upper-left corner of your screen. By default, all notifications are enabled.
These can be problematic in many games, such as the new Black Ops III, because game-critical information like the radar is in that corner. One particularly bad setting is When Friends Join a Party — if you have a lot of friends, this notification could go off every few minutes, and it’s not that necessary to have.
PS4, I don't need to know when friends join a party while I'm watching Netflix.
Now that Spotify is integrated with PS4, you can listen to music while you play. By default, a notifications pings every time a new songs starts, and you probably don’t care about the exact track while you’re playing. Uncheck Current Song at the bottom of the list to stop this.
Other settings depend on if you use their features, but take a look at Community (groups gathered around a game), Requests to Watch Gameplay (using the SharePlay feature), and Events (competitions for specific games). Community and Events aren’t too fleshed-out anyway, so you likely won’t miss much.
