its the phone generation. we have the same issue in work.
alot of people now don't have a decent camera or a computer/ laptop. its all phones, and not phones are equal. some are just crap and incapable to either taking a good photo or saving/ uploading a good photo/. some apps are crap and unless you pay for them you get just basically low res pics/ grids.
ive a wedding photographer friend and he says the amount of people who he will send there on line gallery of photos from there wedding and the bride responds how do I get them on my phone, or ends up screenshooting the hole thing and not being able to save the large files.
