and you need to edit and apply a new configuration, because continuing to use the previous one may result in data misalignment, leading to abnormal use.

After upgrading the firmware, we highly recommend that you complete the following things, otherwise you may experience problems with non-functionality.

1. Calibrate the joystick and trigger of the controller / Calibrate the gyroscope:
To enter the joystick trigger calibration mode, press and hold the View + Menu button for 3 seconds, the light bar will turn orange breathing, which indicates that you are in calibration mode.Turn the joystick 3~5 turns and press the trigger 3~5 times to calibrate.To end the calibration mode, short press the view + menu key, the light bar will double flash orange 2 times, which indicates that the calibration mode has been exited.
If after calibration, you still find problems with the trigger or elsewhere, try resetting 2 more times.Press and hold the LOGO button for more than 10 seconds, the controller will restart and vibrate.
2. After switching off the power, press and hold the LOGO button for more than 10 seconds to reset the controller.
3. You need to delete all the previous configurations in the app and not apply them again.
4. Be sure to upgrade the firmware on both, controller and adapter, and use the new APP.
5. Adapter update: To enter update mode, you need to plug in the computer while holding down the button on the side of the adapter.
