Sony Digital Entertainment Incorporation is under fire after sending PS5 Graphics, Software and Bug Fix update to the PS4 where the software does not have the amount of space and power to handle the size of this update. Sony recommends not updating your PS4
in-case of the explosion or fire. Not Updating your Console results in the disconnection of the PSN(Playstation Network), How ever there is an app called ConnectPSN where your console can connect to playstation servers and you can still be online.
