Unless you can find an app (or get the button fixed), I got nothin'

Depending upon phone, you may be able to repair that yourself.
Search online for 'phone model # Service Manual'

In the case of the Lumia 1520, remove sim & sdcard tray, remove 1 screw, remove housing, either fix (reseat) or replace volume button.

It could also be the ribbon cable that runs along the length of the display. You could pretty easily remove just the housing and inspect that ribbon cable.i had a similar issue with my Lumia 920. Camera button would not work but the camera app worked fine that is how I knew it was likely a hardware issue. When inspecting the ribbon cable I saw that it was marked in between where the camera button was and where the ribbon cable connected to the motherboard. May not be your same issue hope this helps

You're out of luck for the most part.
Now, as people are already helping with, you should look into repairing that button.

You'd have to get that fixed, as apps are not allowed to control your phone in a way that it could take a (useful) screenshot :I
