Tip #5: Silence or mute an incoming call
When a call comes in, you have a couple options. You can answer it on your Watch, or you can also hit that big red reject button. However if you hit the reject button, the person on the other end will know. Instead, you can silence the call by covering the display with your hand. This will silence the incoming call until the other person hangs up.
Tip #6: Hold a call until you find your iPhone
Another nice feature is the ability to tap "Answer on iPhone". What this does is place the person on hold until you can find your iPhone and answer. This is great because it gives you extra time to get your iPhone out instead of rushing and fumbling around for your phone. The person on the other end will hear a short repeated sound until you can get to your iPhone.
