When I'm on fb and try to post a picture comment it doesn't give me the option to select what folder i want to select the picture from. It's just a load of various pics and it takes ages to scroll through. I tried another app i.e. insta and it gives a an option to select a folder. Had to be a fb and android issue.
When you try to upload a picture, have you tried tapping on ‘Gallery’ at the top? There’s a little arrow for a drop down menu, this will contain a list of the pre-existing folders on your phone. Give this a go if you haven’t already! Hope this helps.
Thanks for the suggestion but that option isn't there. Try it for yourself. Go to fb. Try to comment on a post with a picture. It goes to gallery but no option to select folders.
If u not tried this give it a go n let me know. Thanks.
