USB debugging with a cracked screen.

Hello,

I have a Sony Xperia Z3 with a cracked screen. The phone still powers on, I can connect it to my computer and it is recognized as a removable disk but I cannot access the phone files on my PC. I am guessing this is because the phone is not in USB debugging.

Since the screen is cracked and I cannot change any phone settings, is there any other way I could get my computer to recognize the phone as a drive so I can access my files?

I have a replacement plan and a new phone will be here in a few days but I have to send them my broken phone when the new one gets here and would love to get my pictures and videos off my old phone before that.

Thanks!
Jason
