I’ve been using an iPhone since just about the time they were introduced and I just figured this out.
For years I’ve been frustrated by the iOS photo picker. Even on these gigantic iPhones, I have trouble telling very similar shots from one another in the 3 across grid.
If you “pinch out” in the photo picker you can make a photo take up the full width of the phone. And then, you can scroll through photos one by one.
Need to pick a photo from months and months before the current selection? Pinch in, and you’ll zoom out to see way too many photos at once.
Did everyone know about this?
