iPhone 7 /X/8 gets stuck at Call screen,.not able to end the call

<>
There are problem reported with Apple iphone that iphone 5s, 6 stuck on call ending. Even on iPhone 7 and iPhone X/8, Running iOS 10.1.1 and iOS 11. the problem is reported by the user that iphone 7 freezes when calling. Recently bought iPhone 7 gets stuck on the call screen. There is no ringing sound, no sound from the person on the other side of the call. Home Buttons, as well as Lock Screen Buttons, becomes ineffective. User will have to wait until the person on the other end hangs up the call. iPhone frozen on calls and the buttons become unresponsive. The issue is very concerning, especially on a new iPhone. Sometimes only thing you have is to hard reboot to recover from frozen screen of iphone bug. I will recommend reinstalling the iOS with iTunes or iCloud however the chances are that the fix would be temporary.



Fix 1 :  If your using a different sim card/carrier to that when you first activated the phone try this
Update your carrier settings on your iPhone or iPad
Carrier settings updates let your carrier provider update carrier network and related settings to improve cellular network connectivity and performance or add support for features like VoLTE or Wi-Fi Calling. When a carrier setting update is available, you will be prompted to install it. If your carrier releases a mandatory update, you'll see an OK button instead of an Update button to let you know that the update was downloaded and installed. If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier. Hopefully this will fix the issue.

Fix 2: Network provider settings
Possible cause:
You have no Mobile Data connection. Either under Settings > General > Network > Mobile Data is turned off or the network has blocked Mobile Data due to a fault or lack of calling credit.
Also, quite possible that for the described problem you have Settings > General > About > Diagnostics & Usage > Automatically Send selected.
Fix
Go to Settings > General > Network > Mobile Data and turn it back on (if unintentionally switched off.) If intentionally switched off, toggling on then off works for some. Again this is a temporary fix. If you have calling restrictions affecting Mobile Data, get them lifted / buy more credit

In case above fix  did not worked for you, select Settings > General > About > Diagnostics & Usage > Don't Send. N.B. if this your permanent solution don't expect next year's iPhone X to be quite as good as you hoped - Apple need this information to spot software bugs and guide phone design.


Fix 3: Change sim card settings
