How do I switch my Origin account? (PS4)

When I first got BF4 my friend signed in on his account and now I can’t figure out how to change it back to mine. Sorry if this seems like a stupid question, but I seriously don’t know what to do.

Go to main menu press the select button where it pulls up battlelog and it will show your stats and stuff there. I think there should be a log out button there I’m
Not sure though

Sadly there isn’t, EA needs to sort their shit out. Thanks anyways though.

You have to call EA (866-543-5435, within the US) and have a representative manually alter your account. I shit you not.

The entire ordeal takes about ~25-minutes.
