Reports have been coming in overnight on the PS4 subreddit of a message that is reportedly crashing PS4 consoles. Players who have received the message have stated that once the message has been received the PS4 will shut down and enter a boot loop. Various solutions are being presented such as deleting the message using the PS Messaging App on mobile, rebuilding the database, or the drastic step of factory resetting the console.
The main advice though is to change the messaging options on the console so you only receive messages from friends or no one. To do this simply go to settings, account management, privacy settings, personal information, messaging, and selecting one of the above options. It is unclear how widespread this issue is or how many people have been affected. Sony is yet to comment on the glitch.
