ive had my verizon lg cosmos cell phone for about a year and a half. over the past few months the keyboard hasn't been working and ive been using the smaller, front keys. when i try to type on the keyboard the letters either show up too many time or i have to press the button really hard for it to show up. My mom says ive been using it too much and it is overused. could this be the problem or is there any way to fix it without going to the verizon store????
