I had a minor problem with my PS4 last night, I was playing AC then exited and started up Netflix and it hung up on the initial red Netflix screen. It wouldn't respond to the controller or the power button on the console, and the only option I had was to pull the plug. I think I still had a solid white light on while it was hung, but it was very late and I don't 100% remember.
When I powered back up I got an improper shutdown warning and the PS4 ran a check, then everything seemed to OK. My question is, if it happens again, are there any other options I can try to reset the console without unplugging it?
I had this same issue when I exited the Amazon app last night. The system locked up and wouldn't respond, but the controller light and console light were both still on. I held the power button for 10+ seconds to force shutdown and it did a system scan to make sure nothing corrupted when it came back up. I'm hoping as well this was just an OS issue locking up the system and can be fixed with a firmware update and not anything wrong with the hardware itself.
