While in Grid View, the Filters Bar can be visible. If it’s not shown, tap and drag up on the QuickTag Bar. To hide the Filters Bar, drag the QuickTag Bar down.
The Filters Bar changes how groups of photos are displayed in Grid View, by applying Filters (Section 22.214.171.124), changing the Sort order (Section 126.96.36.199), changing the Smart Groupings (Section 188.8.131.52), and the ability to select All photos, Invert the currently selected photos, or Deselecting all photos (Section 184.108.40.206).
The Filters Bar is not visible while in Loupe or Fullscreen Views. Instead of the Filters Bar, you will see a Filmstrip of your photos.
