I don't even HAVE BF4. Just NFS:Rivals, Ghosts, Resogun, Warframe, and Contrast. I can't play ANYTHING but NFS. Warframe crashes and gives me error XXX878-0 and sends me back to the main menu. Resogun gets stuck at the loading screen after I beat the first level. Ghosts will load up to the main menu, but if I select anything, it closes but doesn't give an error. If it DOESN'T close, I get a disc read error that prevents me from going on multiplayer. I hav'en't even tried Contrast.
I called sony and they gave me this BS solution about rebuilding the database after starting in safemode. (that would be the "less drastic" solution). Now I'm "Initializing" (aka full formatting) the system. If that doesn't work I'll be asking for a refund.
Yep! Funnily enough my BF4 crashed last night and the PS4 asked me to send an error message, so I did.
NETFLIX also froze on me the first day, controller stopped responding, power button wouldn't reset the PS4, so I had to pull out the power cable at the back. Don't like doing that but it doesn't seem to have caused any damage.
Hopefully these things will get stabled out over time, it still is early days.
