    Hi folks,
    Recently I am facing tone issue in OP6. During call conversation notification tone ringing when i check (during call conversation) there is no massages or any kind of notification. Also no call recording on by default or accidentally touch.
    Is anybody facing the same?
    What should I do?

    Additional note:- Notification tone ringing only one time during call conversation.
