that sucks

You probably damaged the phone when you dropped it causing the screen to be white all the time. When did you buy the phone? Are there any noticeable marks that make the phone look like it was dropped? If the phone is less than a year old, it will still be under the manufacterer's warranty. Damage from dropping the phone is a user issue, not a manufacturer issue. If a sales rep or tech can tell that the phone has been dropped, I hope you have insurance. If they can't tell, just tell them the problem started after you charged it or something. They would replace it under the manufacterer's warranty.

I dropped my phone and the main screw LCD is all white, but the screen on the outside is fine. How can I fix this problem?
