Hey!i have a problem with the keyboard of my blackberry.its very sensitive when i press the letters. can anyone plz help me?

Did you get it wet? Was it dropped? Did you buy it used?

Something must have happened to it, either when the previous owner had it or when you had it. Water damage can sometimes be cured by letting it dry out for a couple days in a warm place. If it was dropped, nobody can tell you what's wrong until you take it to a repair shop. Too often repairs like that simply aren't worth it and you'd be better served just buying a new BlackBerry.
