My Samsung Galaxy s4's Menu button doesn't work. It does, however, open the menu over and over and over. It seems to be quite random? The phones been in a lifeproof case since I got it and hasn't been out of it except to clean the case screen (was worried something had gotten under the protective screen and that's why the menu button was acting up.) I'm wondering if I should be contacting Samsung or contacting Koodo to get this figured out? I have only had the phone for a month and a half, maybe 2 months. Would really like to get this figured out.
