How do I get out of 3rd person on a PS4 controller?

Solution 1:

By default it is L3 (push the left joystick into the controller, yes, push it down). I think this is very annoying personally as I would constantly accidentally activate it in the minigame days so I would suggest changing it and maybe making L3 a sprint button or just disabling it outright, just preference.

Pressing this button will cycle you through 3 POVs, so just keep pressing it until you get it how he likes it (first person in this case).

If this button doesn't work go to Settings > Controller and see what it says it is set to and change it if wanted. If it is unbound (not set to anything) set it to something.
