Wow didn't know that. And I did experience this first hand last week. Scenery looked very good in gallery, however when posted online it was "blurry", or not what I expected. Thought it was just that the uploaded image did to retain size etc.
Indeed the case that they oversharpen the images in the gallery.
First they treat us like idiots, now they're treating us like morons?
There are enough photo manipulation apps out there to sharpen images if we want the image sharper - Gallery should display the image as it is, with no enhancement at all. I guess this modification is for people who take blurry pictures and never look at them in anything but Gallery - they can now think that the camera is taking clearer pictures.
I wish they'd leave all the working things alone and put their efforts to really making phones better.
