“3D Touch” is the highlight feature of the iPhone 6s and 6s Plus — a way of interacting with the phone by pressing harder on the screen than you regularly would. This is very similar to “Force Touch, only that “Force Touch” works on Apple Watch instead.(although some pointed out that there is a slight difference: 3D Touch has a few more levels of pressure sensitivity than Force Touch.) Shakespeare would probably have told you that a feature by any other name would be as gimmicky, but I digress.
The point of 3D Touch (and Force Touch, for that matter), is to provide quicker access to options or common actions with fewer taps. To put it bluntly, it’s really just a glorified long press or right click. That doesn’t mean it’s not without its advantages, but it’s more of an evolutionary feature than a revolutionary one.
One of the first apps to jump on the 3D Touch bandwagon was Instagram, letting users preview an image in search results by pressing harder on it. After a couple of months of trialling on iOS, they likely realized that you don’t actually need a force-sensitive touchscreen to preview an image, and decided to port the feature over to Android.
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 APK Mirror.
