By default the collections and years views in the Photos app don't show all your photos — but you can change that.

If you use the Photos app on your iPhone or iPad to sort, organize, and find your photos, there are lots of ways you can make that task easier. While one is simply using the search feature, another is by adjust exactly what the Photos tab shows under the Collections and Years views. By default you only see a summary of photos that iOS picks at random. If you'd rather see all your photos in these views, you just have to change a setting!

How to view all photos in Collections and Years, not just summaries

  1. Launch the Settings app on your iPhone or iPad.
  2. Tap on Photos & Camera.
  3. Turn Off the option for Summarize Photos.
