Reset Your Controller

• First off, you have to press and hold the PS button on your controller for around 10 seconds until the flickering light stops and your controller will be turned off completely
• Then, you need to locate the reset button on your controller, which is found in a very narrow hole at a certain part of your controller
• Once located, use a sharp object such as a safety pin to press the button and reset your controller to its default settings

This button is designed in such a way to prevent accidental reset of the controller. If you’re unable to locate the button on your own, you can also check the manual to determine where the reset button is located on your PS4.

Reset Your Console’s Firmware

In case the above two solutions don’t work for you, there’s a high chance that it is occurring because of corrupt or outdated firmware of your PlayStation 4 console. With that said, resetting the console might help you mitigate the error permanently. To reset your PS4 right away, follow the steps given below:

• First of all, turn off your PlayStation 4 completely by keeping the power button pressed for 8-10 seconds. Then, boot it into safe mode by again holding the power button until you hear two beep sounds from the console
