Calling specific contact makes phone turn off
Every time I call a specific contact the following happens: After several minutes suddenly the pone turns off so I restart it, enter my passcode and the SIM PIN. When I call the contact to continue our conversation the call ends. That happened at least 4 times now, so annoying.
The contact is not stored in the regular phone app but in the hidden storage of OpenContacts (opencontacts.open.com.opencontacts version 20.0). I start the call by clicking on the contact’s home screen widget.
