There are a few things that could be causing your R2 button not to work on your PS5 controller.
If your PS5 controller R2 button isn’t working, there are a few things you can try to fix the issue. First, make sure that the button is not stuck or obstructed in any way. If it seems to be stuck, try gently pushing and releasing the button to see if that clears the problem.
The first thing you should do is try cleaning the button and the controller itself. If that doesn’t work, you may need to replace the button or the controller.
If you’re still having trouble with your R2 button not working, you can try contacting Sony customer support for assistance.
