Hi,
The phone app in my iPhone 5S is not responding and is stuck in contacts tab. I am not able to make any calls or go to other tabs - recents, keypad, etc. All other apps are working fine. Also, I can't go in the Phone option in 'Setting's.
iPhone 5s, iOS 9.1
Hey m_varghese,

If I understand correctly, the Phone app isn't responding on your iPhone 5s. Take a look at the article below and try the general troubleshooting tips that it provides, which can resolve issues with any app.
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
If the issue persists, try restoring your iPhone as shown here:
