Spinning wheel on black background when starting a call
I have a Nexus 5 16 GB, stock everything, never tampered.
For a few days, when I try to make a call in the stock Android dialer, a black background with a small spinning wheel in the middle appears,
then after a few seconds (~5 sec) the regular screen with the contact picture and the end call button is back, and it seems than only now the call is really made. But during the black spin wheel screen I cannot do anything and I don't think the call is going through.
I've tried clearing app data for the dialer, restarting the phone, clearing the system cache, but no success.
Did anyone else experience this?
