iPhone Display Zoom Not Working - Fix Guide
iPhone offers two types of zoom features: Display Zoom (scales the entire UI larger) and Accessibility Zoom (magnifies portions of the screen). Here's how to fix both when they're not working.
📱 Display Zoom (UI Scaling)
Makes app icons, text, and UI elements larger system-wide:
- Settings → Display & Brightness
- Tap Display Zoom (at bottom)
- Choose Larger Text for zoomed view
- Tap Done, then Use Zoomed
Note: iPhone will restart to apply the change.
⚠️ Display Zoom Missing?
Not all iPhones support Display Zoom:
- Supported: iPhone 6 Plus and larger models
- Not Supported: iPhone SE, iPhone mini models
- Check if your model has the option in Display & Brightness
On newer iPhones (14/15/16), look for "Display Zoom" at the bottom of Display & Brightness settings.
