GameSir G8 Galileo Trigger Not Working

You are going to need a few items. A soft toothbrush or small brush, a cloth, and a cotton swab with alcohol on it. First make sure that the controller is turned off, then wipe around the trigger with your cloth that you have to make sure that all of the exterior debris is off. Then brush gently around the trigger and inside under the cover of the trigger so clean out debris. The cotton swab with alcohol is for any substances that have gotten on the trigger, so you will gently rub all around the trigger getting all of those substances out, then leave to sit for 10 minutes to dry. Avoid using water or harsh cleaners.
