Help Dropped S2, would like to know what the problem is

[saltheman]

So I dropped my S2 on coffee table yesterday evening, it was working fine but was coloured blueish on the edge of screen. This morning the screen was blank, but everything is working fine, the keys and numbers light up blue and the touch also works, note: the screen has two small cracks too. Is this the digitizer that is broken?

If the touch screen is working e.g. haptic feedback is felt when screen is touched, then the LCD panel itself is probably damaged I'm afraid.
