How can I sort my photos by date on my iPhone 5 running iOS 8?

[iMore Question]

I have iphone 5 with ios 8. I never used the Icloud so I still have the camera roll with all my photos. The problem is that the photos got mixed, they used to be organized by dates, but not anymore and it's really annoying!! How can I sort it by date??

Select "Photos" at the bottom of the screen.
