Instagram Introduces 3D Touch feature to its Android app

The newest update of Instagram is almost identical to the iOS app’s use of 3D Touch. When you long press a thumbnail image (you’ll see this layout when searching or viewing someone’s profile) a full-size expansion of the photo will appear.

users can now long press on an image thumbnail to zoom in on it. Dragging their finger away from the center of the image shrinks it back down to thumbnail size, and moving over one of the buttons under the picture lets them like or share it without ever having to lift their finger. There's even a pleasant haptic feedback given when hovering over one of the buttons.

The new feature is enabled on version 7.13.0 of the app, which you can download from Play Store or grab the latest version from APK Mirror. 

However, Instagram has not officially announced this new feature, It might be that there is some sorts of testing going or maybe Apple may ask them to remove this features.
