Is it possible to stop notifications like whatsapp not to show if you are busy on your phone for instance you are busy sending a whatsapp - if another whatsapp comes in then it still shows on the watch although you are busy on the app. And does it have a function like Samsung smart watches that you need to turn your arm to see notifications - currently my whatsapp messages just pops up on my watch for anyone to see even if my screensaver is on.
