Sony has released a firmware update for the PlayStation 4 that is designed to fix a corrupted system. The update, which is available as an automatic download, will install on systems that are experiencing problems with online play or game saves. The update is not mandatory, but it is recommended that all PS4 owners install it in order to avoid potential problems. If you have not yet installed the update, you can find instructions on how to do so here. If you have already installed the update and are still experiencing problems, there are a few things that you can do. First, try restarting your system and your PlayStation 4 console. If that does not work, try reinstalling the game or app that is causing the problem. Finally, if all of those options fail, you may need to contact Sony customer support for assistance. ..
