Google Photos has been adding new features off late like movie editor for web, search for text in pictures, manual face tagging, and more. On similar lines now, Google Photos v4.33 update lets users zoom in while watching videos and as of now, it is an unreleased feature.
According to a report from XDA Developers, Google is testing the feature in the Photos app and the feature is pretty straightforward. Users can pinch to zoom into videos and it works as expected. Until now, Google Photos allowed users to zoom into photos, but not videos. This upcoming feature should be a nifty addition and should be useful to a lot of users.
However, the feature is still in testing and we can expect Google to roll it to all users soon.
