Ps4 controller after connecting to the phone again to connect to the PS4?

How do I connect my Ps4 Controller to the PS4 after connecting it to my phone again? I urgently need help.

Hi, you just need to connect the controller to the PS4 with the cable and then press the PS button.

Thanks, but I have already tried and does not work.

Oh pity: / I can only advise you again to use another cable. I once had the same problem and somehow the PS4 does not recognize all the cables that work normally.

OK, thanks, I'll try it ;-)
