okay, so I cracked the screen on my Nexus 4 and the phone is useless. it still turns on and everything but I cant use the screen. can anyone help me with the memory on the phone? when I plug it into the computer, it says that there are no pictures or anything on the device. I just want all the music, pictures and contacts from the phone before sending it off to get fixed because they say they'll wipe it completely. Is there a way where I could fix the screen and whatever else is broken myself so that I still have all the pictures and whatnot on the phone?
