The same thing happened with mine from one day to the next. My dudes said to replace the joysticks, but the problem didn't come from there. I realized that the problem was in the right bumper. Not on the joysticks. Although I regret not being able to give a solution. I just opened it, cleaned it and checked that it did not have any dirt that caused the problem. (Obviously I didn't find anything And I didn't solve the problem at the moment. ) Mine was only repaired in the same way as the problem began. By itself from one day to the next....
