White screen phone works but white screen

Did you drop it in water, ?did you press the screen to hard and cracked the lcd panel? those are the most common reasons, oh, and dropping it, and also dropping it in water. I would suggest going over all those possibilities.. open up the back of your phone and pull out the battery, in all phones now they have a water sensor dot, it remains white always unless the phone was damaged by water, and warranty doesnt cover water damage, look for that little white dot, if its red, that means you gotta get a new phone, and if you try peeling if off theyll know youre covering up water damage, unless you were able to somehow obtain another white color changing dot to put back in your phone now in the exact place it should be, but techs are very good at catching bluffs. but if that white is intact to begin with, your phone should be under warrenty of some sort, and that means they owe you a new one. bottom line.
