Call management app crushing in nougat 7

[Andyv4446]

After making some calls the call management app crushes and i can't call any no. Unless I restart the phone again 

This bug appeared after the latest software update 

Any ideas on how to fix this bug

@Andy4446 if you recently updated to Nougat there are two ways to fix the issue:

1) Is to go in Settings, Apps. Open the top menu (are three vertical dots) and select "Show System".

Search for the Phone, Phone and Messaging Storage and Phone Services. Tap to each app and go into Storage, select Clear Cache and then Clear Data. Restart the phone and check if it works.

If after the restart the issue isn't fixed follow next step:

2) Perform a software repair using Xperia Companion, that should fix definitively all the issues you had after the upgrade to Nougat.
