Hello and welcome to Apple Support Communities tharaka_nuwan,

Thank you for contacting us. We see that Field Test Mode isn’t working on your iPhone since upgrading to iOS 15, and we're glad to provide assistance.

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open -- If you’re using an app to test your carrier’s signal strength, even though the title of this article doesn’t exactly match your issue, the steps it contains can help.

If you’re not using an app, we recommend contacting your carrier for help.

Thank you for contacting Apple Support Communities.

Best regards.
