i dropped my phone and screen has been white ever since
Hello Mohagany, the white screen is a solid indicator that the LCD has been damaged and needs to be replaced. The LCD is only responsible for displaying an image on the screen, so if there is no image unusually there’s a problem with the lcd. You should go ahead and replace your lcd/digitizer with a new one to get the phone working properly again. Best of luck with your repair.
the main caused of it is because you dropped your phone. You can go to a local phone store to get it fixed.
