Joining the rest of the Google apps on the iOS platform, Google Hangouts just got an update to optimize it for iPhone X. This means Google’s dedicated messaging app will take advantage of the iPhone X’s immersive display and gets rid of the black bars at the top and the bottom. Aside from this, Google didn’t introduce anything new to the app. But if you have the iPhone X and use this messaging app, it might be time to update your app.
