I connected my nephew's PS4 controller to my Note 20 Ultra, and now it won't connect back to the PS4. Any ideas? All I get is a slow blinking white light when I try to turn it on.
Reconnect DUALSHOCK 4 wireless controller to your console
To reconnect your wireless controller to your PS5 console or PS4 console, connect it with a compatible USB cable and press the PS button on the wireless controller. You can then remove the USB cable and use the controller wirelessly.
