Peek and Pop

With 3D Touch on the iPhone 6s, you can use the new features Peek and Pop. You can use this is in the Messages app (with convos), Mail app (with emails), links, and more! To use Peek and Pop on an eligible item, just press hard on it to Peek and press even harder to Pop. Peek gives you a preview of your content and Pop lets you view it in full screen. In Peek mode, you can swipe up to reveal options, like quick replies in Messages. I hope this helps!
