Sony has released a new firmware update for the PlayStation 4 that is designed to improve overall system performance. However, some users have reported that their controllers are displaying a light green hue. This issue seems to be affecting a small number of users, and Sony has yet to provide a definitive explanation for why it’s happening. However, some theories suggest that the light green hue could be caused by interference from other electronic devices in close proximity to the controller. If you’re experiencing this issue on your PS4, you can try downloading the latest firmware update and see if that resolves the problem. If not, you may want to consider contacting Sony customer support for further assistance. ..
