I'm receiveing messages and I can still hear everything, but the display is completely black. I took out the battery and put it back in, but that didn't help. I tried powering it up to see if that would help, but it did nothing, its already powered. I need help, I'm getting a lot of messages and I cannot read them. This is very frustrating, I just topped up my phone and everything. It fell out of my pocket when I was getting into my car, but its not even cracked or anything. Just a blank screen.
