[q] nexus 4 backup topic

Hi

i stupidly dropped my nexus 4 on the floor and the screen completely smashed, the buttons work fine, but my phone is locked so whenever i connect to my laptop it wont backup my files.

Is there anyway i can backup my pictures and videos?

Any help or suggestions will be greatly appreciated, as i have some memoroable pictures stored on there?

Thanks
