A Sony PlayStation 4 wireless dualshock 4 controller relies on colored lighting to indicate a certain state or error to a user so if yours has a flashing blue light showing up, you’ll need to check if it’s paired or synced to another device. An unstable or unsuccessful connection is usually the reason for a flashing blue light PS4 controller.
Restart the PS4 controller
Normally, the light bar on the controller will keep flashing a blue light when it’s not connected to the console or having an issue maintaining a connection. This can also be true if you use it when playing a game like Call of Duty Mobile on non-PlayStation devices like phones or tablets.
In order to fix the issue, you’ll have to do a couple of things. First, you can restart the controller. This is the easiest way to fix this problem most of the time. Make sure that the controller is charged for at least 30 minutes before you restart and reconnect to a console, phone, or tablet. This can work if your controller’s battery is weak or can no longer hold a charge for very long. Just press and hold the PlayStation button (between the two analog sticks) for about 10 seconds. This is going to turn off the controller.
Reset the PS4 controller
If you press the PS button or restarting the controller won’t help at all, the next good thing that you can do is to reset it (works like a safe mode procedure). Resetting the controller will return the controller’s firmware and software settings to defaults, disconnecting previously paired devices, and clearing any connection bugs that might prevent it from working properly.
To reset your PS4 controller, you’re going to need a wooden toothpick or a bobby pin.
Resetting a PlayStation 4 Controller that’s flashing blue light
Time Needed : 1 minutes
Below are the steps on how to reset your PlayStation 4 controller:
- Turn off the controller.
Press and hold the PS button for 10 seconds.
- Press the reset button.
Using a toothpick or bobby pin, press the reset button (inside a tiny hole) at the bottom of the left trigger. Try to press and hold this button for about 3 seconds. You might hear two beeps indicating that the reset is successful.
Once you’ve reset the PS4 controller, check for the flashing blue light issue after you charge it using the USB cable for about 30 minutes. You may also press and hold the power button to give the PS4 controller a soft reset.
