After upgrading the iOS version to iOS 11 many users found an annoying bug in the Apple products, is when they opened "Camera Roll" album, the pictures are no longer in chronological order or out of date sequence. Photos from 3 years ago are appearing as my most recent photos! This is such a big problem for users who are saving thousands of images in their iphone. Unfathomably annoying. However all pictures seem to be in chronological order when accessed via the "Photos" tab. The problem is even reported with Apple latest release of iOS11.0.3 without any fix for the issue. You can try below fixes to solve the photos out of sequence issue.
iOS 11 camera roll pictures not in chronological order.
Camera Roll pictures out of order
Fix 1: Hard reset
Hard reset the phone and the photos in the camera roll are back to time sequence order.
Fix 2: Duplicate camera roll photos
It involves selecting the photos out of order and then duplicating them. Obliviously, you need to duplicate them in the proper order to add to the bottom of the roll. Seeing as my photos were just divided at a certain point in 2014, it didn't take long for me. The only thing I lost were burst photos I did not save inside the burst. Everything else including live photos, video, panoramas, etc. copied.
