that's not a defense, there are countless scanning apps for phones and tablets which magically correct the perspective and distortion and remove the creases. In a way, these are even better than scanners because they have a very high resolution.

Adobe Scan is a free phone app for creating scans of docs. There are dozens of others like it.

I get that, but theres no excuse for letting your apps crush photos (if I remember my iPhone days correctly it literally asks you if you want to compress or send full quality when you attach) or sending a drive link instead of a file.
