Chosen Solution

My son decided to knock my phone down a couple months ago and cracked my screen 2 months later my screen quit working and 3 hours later started turning purple and now completely black. I have a password on it. Is there a way to retrieve the files, pictures and data off it? My SD card apparently didn’t save everything and there stuff on my internal memory. I wamt to try to get the stuff back before i turn it in as i have important files on it. Anything welcome.

You have a broken LCD which is causing the issue with seeing anything. Replacing the screen will restore functionality for you but, as I’m sure you’ve noticed, this can be expensive! You can use a data/charging cable connected to the computer or Using Samsung KIES. http://www.samsung.com/in/support/useful
