Maybe its just the touchkeys which are faulty. Because I use the sports /comfort/ eco pro mode button and the start button more frequently with no signs of deterioration. So it can't be the way I am using the buttons or anything peculiar to my skin or natural oils. Unless these buttons are made in a different manufacturing process.
