The button is pretty loose and I have to use my finger nail to try to get it to come on, if it doesn't come on after many tries I have to plug it into the charger or wait till someone calls me. If by chance I get it to come on with the button then I can't shut it off with the button and have to wait until the screen turns off after a minute. The button is also a little more recessed than it should be. Any ideas? Can I open it up and check the button or would that not be a good idea?
