Why does my controller randomly presses buttons?
Whenever I play a game the controller justs starts choosing options that match the buttons out of nowhere without them being pressed. For Example I'll play call of duty and all of the sudden I'll start switching weapons or shooting without me pressing the button.
I would suggest you open up your controller and clean the contacts. If things get stuck in there or if its grounding out for some reason across the contacts you'll get the behavior as described.
Use this guide to help you open it up.
P.S. the clear contact sheet that the buttons press on shouldn't be bent or crinkled.
Hope this helps.
