first drop the phone from 1 meter up

Answer

I had a phone do this and believe it or not if yours is having the same problem you can put it in the freezer for 5-10 minutes and get about 5 minutes of screen time to recover important messages or contacts. I don't know why but being a computer nerd I figured a deep freeze may help and it did!
