[Q] Get data from cracked Nexus 4 topic

I have a Nexus 4 in front of me with a diagonal crack from top left to bottom right corners of the screen.
The touch screen only responds on the upper half of the phone.
I have been tasked with getting the images, videos, music etc. from this phone, however as I am unable to unlock the phone I am finding it pretty difficult!

Is there any way to get the data from the phone using either software or hardware hacks?
I know there are a lot of very knowledgeable people on this forum, any information is appreciated, even if I have to open up the phone and start cutting wires!

Thank you,
- Pano
