Dailer not working on Xperia XZ

[Rubir]

Hello. I am facing this issue that i am not able to call anyone coz the screen goes black immediately after i hit the dialer sign even when i haven't put it on my ear.  Then neither the phone gets connected nor i can dial again. I have to restart the mobile again which takes a lot of time. 

It started after my nougat update. Its really frustrating. Can anyone help me in this regard? Its really frustrating 😤 that i cant do the primary function with my phome which its built for.

@Rubir could you try restarting your phone in safe mode just to verify if it's a software issue? I believe something went wrong during the Nougat update, you may want to backup your data and trying a software repair using Xperia Companion
