Controller B button not working

I'm trying to use a controller with my phone
Everything works fine except the B button with any controller, it does not work.

After some research it seems like the touch gesture feature is intercepting the B button nav_code.
B button is 305, so i think this line cause the issue :

private static final int FP_GESTURE_LONG_PRESS = 305;

In logcat the B button is correctly detected as 305, but i'm unable to bind the button in any other app.
