I uses ng-repeat to get multiple phone numbers
Having autofocus multiple times in your page is not forbidden, but does not look right based on the documentationm, https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input
It saysOnly one form element in a document can have the autofocus attribute
autofocus HTML5 This Boolean attribute lets you specify that a form control should have input focus when the page loads, unless the user overrides it, for example by typing in a different control. Only one form element in a document can have the autofocus attribute, which is a Boolean. It cannot be applied if the type attribute is set to hidden (that is, you cannot automatically set focus to a hidden control).
I would not to use autofocus within ng-repeat and set focus manually after it is added.
