iOS 18 has brought some changes to the Photos app that may be annoying for some users. The main issue is the cluttered interface, which shows random collections and albums at the bottom of the screen. To customize the Photos app, swipe down to the bottom and tap “Customize and Reorder.” This will allow you to uncheck unwanted collections and organize the order in which they appear.
Another feature that’s causing frustration for some users is the new Control Center layout, which has multiple pages of controls. To get back to the single-page layout, simply swipe up on any blank page and press the “remove control” button at the top-left corner until all extra pages are gone.
Additionally, some users have reported issues with Siri’s Type to Siri feature, which is enabled by double tapping at the bottom center of the screen. This can be disabled in Settings > Apple Intelligence & Siri > Talk & Type to Siri without disabling the assistant entirely.
By making these simple tweaks, you can customize your iPhone Photos app and Control Center to better suit your needs.
