Numerous PS4 owners on Reddit and across social media warn about a message that contains a number of characters that allegedly can cause the Sony consoles to grab and crash. In some cases, the console is so mixed up from this error that users perform a factory reset on the hardware to make it work normally again.
We've seen errors on this type on mobile platforms where a particular message or odd character can cause chaos and cause unstable behavior. If the reports are true, Sony will likely act quickly to roll out a firmware update that eliminates the problem. After all, this company loves to issue updates that improve system performance and stability.
If you receive the message, delete it from Sony's PlayStation Messages app for Android or iOS instead of opening it on the console.
There are reports of deleting the suspicious message with Sony's smartphone app before Streaming your console and logging into the PlayStation Network is enough to avoid problems. The Sony PS4 messaging app is a free download and available on both Android and iOS.
To restrict messages on PlayStation 4 to friends only:
A) From a browser, you can visit this URL. Log in with your PS4 account credentials. Select "Personal Info | Messages" and then select the edit button near Messages. From here you can choose someone, only friends or no one. Until Sony resolves this error, you should choose one of the last two options.
B) From the PS4 console go to Settings -> Account Management -> Privacy Settings. Select "Personal Info | Messages" and then select the edit button near Messages. From here you can choose someone, only friends or no one. Until Sony resolves this error, you should choose one of the last two options.
How to rebuild your PS4 system database:
If you're affected and find your PS4 working funky even after you've quit the message, you might want to start the console in a safe mood and rebuild the database. This process should not affect any of your stored data. Here's what Sony says it does:
Scans the drive and creates a new database of all content on the system. This operation may take a long time, depending on the type and number of data items.
This option is useful for cleaning up the data on your PS4 because it reorganizes everything on your hard drive. Select this option if you experience issues like freezes or frame rate droplets.
Doing this definitely sounds like a good step to get everything straightened out if any jerk hits you with the bad message.
