Snapchat updates app with one-hand zoom feature

New York: Photo and video messaging app Snapchat has rolled out a new update that enables users to zoom in via a camera without needing to lift the thumb off the capture button. In previous versions, the only way to zoom in was to use two hands -- one hand on the capture button and the other (with a pinch gesture) to zoom in, tech website reported on Tuesday. Once a user has updated the Snapchat app, it will allow the user to drag a finger up and away from the capture button. Snapchat has over 100 million daily users and its influence has grown in the past year because of expanded partnerships with media companies, sports leagues and live events.
