Maybe you also can try it.
yes, the thickness of the screen protector affects the sensitivity..
my phone (S5360) has a quite thick screen protector and it makes the back and menu buttons dont work.. and then magically working again..
my friend has a thin one, and his buttons work well even its covered.
other tip: try cutting your screen protector to fit only the screen. so it dont block the back and menu button.
