Hi, I'mCustomer Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
I'm sorry about the issue, If you have photos in your Nokia 625 and you can't use it because of the faulty screen, all you have to do is to transfer the photos from your Nokia 625 to your computer then from the computer to your new Microsoft 640 xl.
Please Connect your Nokia 625 to to your computer's USB port. On the computer open file manager.
Double click on the icon or folder of your Nokia device.
Open to the folder that contains your photos
Highlight the photos and move or copy it to the required location.
Now connect your new Phone and transfer the photos from the computer to your new phone
Let me know if you need further assistance
Has everything worked out, do you still need help please?
