Infotainment sometimes won't hang up a telephone call

[Moiz]

Hi, New Lexux LC 500h owner of a 2017 model. Love it, but when someone calls me I sometimes can't hang up the call on the head unit, either on the steering wheel or elsewhere. It simply hangs and says its on a call when it's not. Have to stop the car, turn everything off and restart. Not handy on a busy motorway!!! Any idea what's wrong and if there's a fix for this. How do you reset the head unit when driving, if possible?? Cheers

I have never seen this problem

What phone do you have?

To reset the Infotainment system just hold down the radio on button for 3 to 5 seconds and will restart without turning off the ignition.

Thanks for the info.  I will give that a try if it happens again.
