if someone had this problem in the past ,please help me, it is about the proximity sensor of an iphone 4s !, changed the display,changed the flex , put the gasket and no luck !!

If i take out the flex with the sensor and put my hand on it works but the wrong way , in fact it works in revers !! when it's covered the screen appears and when it's not cover the screen is black . . when in case the screen is always on!!

anyone have any idea? thanks
