After updating to android 7.1, my xperia x call waiting is not working well.
When it's on (activated) and I talk with a person and someone is calling me, the first call is put on hold, both me and the interlocutor can't hear anything and the phone is ringing. When I answer, it asks me what to do (to end the first conversation or to keep on hold).
Before update, during a call, I could hear a sound when other person was calling, but the first conversation wasn't interrupted.
I've tried to deactivate the activate the function, but the problem persists.
Someone have a suggestion? I need this function very much.
