The option of Edit>prefrence>replace document colors. doesn't work on scanned pdf, but in the android app the night mode works even eith scanned pdf.
so is there a way to turn the background of a scanned pdf to black with Adobe reader desktop version?
What makes it possible on mobile devices while preventing it from working on PCs?
The night mode is only available in mobile devices.
I am having the same problem.. i think it's more to do with android Vs windows..
