Video zoom in on pinch or double-tap is introduced to Google photos. The app version does not matter, but the android version matters! We could only update this feature only after updating your phone to Android 5.28.0. This feature is really appreciable and users can now easily look at the details of the video by pinching or double-tapping the screen. This new feature has started rolling out for some users.
To check whether the update has rolled out on your device or not, you can try updating the latest Google photos. As this update is server-side, so it is quite possible that the update comes in batches. The update hasn’t arrived on the iOS device.
Google has rolled out amazing features these days like Cinematic photos, the 3D-like effects for some of your images, maps timeline feature and etc.
