Since a couple of month Ingress has this share button on certain screens (most useful one is probably the player profile). If you press that, it opens a selection of where you want to share the picture, and takes a full-size screenshot.
On Android, you can just press the back-button and not do anything and the screenshot will end up as an image file in your phone's library (but in a separate folder). However, on iOS I cannot find the file. If you select G+ or similar target, you can upload it. But it doesn't go in the image library and it doesn't seem to go anywhere else.
I want to archive those screenshots. Where do they go?
