Call Waiting on S8 GRRR

[Unclebunky1966]

Ok so i am on a call, when another call comes in, it automatically puts my call on hold and gives me the option to answer the incoming call WTF, normally you can say to the other person hang on i need to answer this call, and put them on hold,not just get cut off.
I ve disabled call waiting for now my HTC 10 didnt do this.
any any else had issues ??

Cheers
Mark
