The Samsung Galaxy Note 5 integrates a couple accessibility features to help you to manage your incoming calls. You can, for example, use voice commands to answer and reject calls. You simply have to say "Answer" to answer an incoming call or "Reject" if you don't want to answer the call. To enable this small accessibility feature:
Go to Settings > Personal > Accessibility > Answering and ending calls. Toggle the Using voice commands switch on and that's it.
You can also enable the following options for the same menu:
- End calls by pressing the Power key.
- Answer calls by pressing the Home key.
