If you're a Snapchat user for the longest time, you've probably had calluses grow on your finger if you view a lot of snaps and stories on the app. That's because, for those who don't know, you have to hold a finger down in order to view them. That's okay if it's just a single picture. But if you're watching a 30 second video, it gets kind of annoying. A new update to the ephemeral messaging app now allows you to just tap to view, and brings other features as well.
