My S4 dropped from my trouser pocket and fell face first onto our laminate wood flooring. I assumed everything was fine but when i tried using the phone, you screen stayed black white a few outlined light marks. Upon closer inspection on the phone, you can a crack under the glass where the LCD has smashed from. It seems rather strange that LCD beneath the glass has broken although the glass is fine. I've seen people with totally smashed screens still being able to use their phones but i'm guessing im one of the unlucky ones been quoted
