Skype to add new video call and IM features to iOS and Android; users can now test them on Skype Preview
First off, there's a new integrated camera perk, which means you can swipe to quickly capture an image on your screen. After that, you can add emojis, annotations and stickers, and then share your moment directly with the rest of the chat. There is also the addition of in-call and messaging reactions. The former lets you add photos, emoticons and text to your video calls in real time, while the latter essentially allows users to respond to each individual text message with likes and reactions (just like the ones found below a Facebook post).
As we mentioned earlier, these new features are currently being tested, but users on iOS and Android can check them out through Skype Preview before they are introduced to the main app. Android users can download Skype Preview via Google Play, while iOS users can apply for Skype Insider.
