Stk7009f not working

Hiya, I lately purchased a stk 7009f controller and that i'm having hassle utilizing It with my telephone. The controller join on the telephone with no downside by way of BT, however the app Shootingplus V3 doesnt recognise any of the button of the controller or they behave erraticly. The left Stick refuse to maneuver and Is caught on the highest left nook of the display, and the a/b/x/y buttons and the precise stick simply don't work in any respect( you possibly can see the spherical factor prime left) I believe It Is a few kind of app auth/bug, however I don't know tips on how to remedy It.
