Hello I can't open my note app is there anyone to help me and my iphone is iphone4G

Hi there Sorror,

Welcome to Apple Support Communities.

If I understand correctly, there's an issue opening a note or the Notes app on your iPhone 4. Try the general app troubleshooting tips in the article below.

If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support

Restart the app

Close the app and open it again.

Restart your device

Turn your device off and back on.

If the issue persists, try restoring your iPhone as described here:

Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support

Take care.
