I accidentally dropped my phone yesterday and when I turned it on, a white background with line streaks appeared on the screen of my phone. I tried to tapped the screen on my phone (since it is a touch screen phone) but it is not working so I turned it off again then I removed the battery and reinserted it. Unfortunately, when I turned on my phone again there is still a white background with line streaks. What should I do? I badly need help.
