Hello, recently i dropped my note 3 and i think i broke the LCD. At first it was going all crazy and clicking random things by itself because i think their is a crack down by the bottom of the screen. Eventually I got it and tried tapping the screen with my knuckles to get it to stop going crazy. Now i can hear the volume and vibrations, bottom buttons light up etc, but I only have a black screen. When i push the home button i see a quick flash of green across the middle of the screen but that's it. Did i crack the LCD? What do i need to do to fix it? Thanks for your help.
