Antwoord op "How to answer call?"You do not need to play with the settings actually. Answering the phone is slightly different on the OnePlus. You put your finger on the middle "blue" handset circle first and then swipe to the right , towards the small green handset to answer, or to the left towards the small red handset to reject. I.e. it does not work like most other phones by simply swiping across the screen.
