iOS 12.1.1 has seen Live Photos in FaceTime come back, and some UI changes too.
As spotted by 9to5Mac, Apple has now brought Live Photos in FaceTime back, removed when iOS 12.0 was in beta. FaceTime has also seen another facelift with a revamped interface.
Live Photos in FaceTime requires both devices in the call to be updated to iOS 12.1.1 in order to work.
FaceTime Live Photos lets you quickly capture a good moment on your FaceTime call without having to screenshot your whole screen. It's similar to Live Photos on iPhone 6S and newer.
FaceTime's expanded card view has changed a lot, too, and now brings the Flip Camera and Mute buttons to the top, making it quicker to get to. Before this, these buttons were buried in the card view, where you would have to open it, and it would cover the whole screen.
This interface has been reworked and tweaked in iOS 12.1.1 Beta 1. The new row of four buttons still features the Effects button, but it's been made smaller, and now sees the Mute Call and Flip Camera button, along with the End button.
We may see this interface change yet again in the next few betas.
