If you have a friend who's already done it go to their profile page and there should be a post about it: "so-and-so added a temporary profile picture... Try it"
Click on "Try it". How to do it if you don't have any friends I can't find yet.
I've been trying to do this for hours and can't get it to work. Have clicked on the 'try it' butto when a friend has posted and it appears to do something but my profile picture remains the same. Any suggestions please?
You have to allow your phone or iPad access to your camera. Go to Settings and slide the button so it shows green. That's what I did when I finally could see the "Try It" button.
Still can't do it - get the 'try it' button but no 'use it' - it appears to give me the tricolour over my profile picture but when I go back to my facebook page, nothing's changed.
Will keep trying - maybe f/b as run out of 'use it' buttons and awaits a delivery of them!
