Ok so about 2 months ago my Nexus S 4g was dropped and the screen has been shattered. it still turns on but i am unable to see the display or use the touch screen. i have had the phone for a year and have a lot of pics/app data/videos that i do not want to lose before i buy a new phone. so is there any way i can turn on usb storage from my computer without having to actually touch the option on the phone itself?
