iPhone 13 random blurry home screen

If you're experiencing a blurry home screen on your iPhone 13, there are several steps you can try to resolve the issue:

1. Restart your iPhone: Sometimes, a simple restart of your iPhone can resolve the issue. To restart your iPhone, press and hold the side button and either volume button until the power off slider appears. Then, swipe the slider to turn off your iPhone. Wait a few seconds, then press and hold the side button until you see the Apple logo.
2. Update to the latest software: Make sure that your iPhone is running the latest version of iOS. You can check for updates by going to "Settings" > "General" > "Software Update." If an update is available, download and install it.
3. Check for any updates to your apps: If the issue persists after updating your software, make sure that your apps are also up-to-date. You can check for updates by going to the App Store and tapping "Updates."
4. Turn off transparency and reduce motion: If the issue is related to transparency or motion effects on your home screen, try turning them off. To do this, go to "Settings" > "General" > "Accessibility" > "Reduce Motion" and toggle the switch to "On." Then go to "Settings" > "General" > "Accessibility" > "Increase Contrast" > "Reduce Transparency" and toggle the switch to "On."
5. Reset your iPhone: If the issue persists, try resetting your iPhone. This will erase all of your settings and data and restore your iPhone to its original state. To reset your iPhone, go to "Settings" > "General" > "Reset" > "Erase All Content and Settings."

If the issue is still not resolved after trying these steps, you may want to reach out to Apple Support for further assistance.

"How to restart your iPhone X, 11, 12, 13, or later

Press and hold either volume button and the side button until the power-off slider appears.

Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

If that doesn't resolve the issue, does your iPhone need updating to iOS 16.3.1? Do you have a recent backup for the data in your iPhone in iCloud or your computer? If not, we recommend that you create one as described here: How to back up your iPhone, iPad, and iPod touch - Apple Support

Then update your iOS as outlined here:  Update your iPhone or iPad - Apple Support

We hope this helps.
