One week after pushing out iOS 12.1 beta 3, Apple is sending a new beta update.
iOS 12.1 beta 4 is now available to registered developers, who can grab it by going to Settings > General > Software Update on their iPhone or iPad. It's also available on the web through Apple's Developer Center.
The update to iOS 12.1 brings with it new features like eSIM, which will enable dual SIM support on the iPhone XS and iPhone XS Max. The update also includes real-time depth control for Portrait Mode photos and Group FaceTime. Apple has confirmed that iOS 12.1 will also bring more than 70 new emoji, including a bagel, a cupcake, a raccoon, and a skateboard.
Apple hasn't announced when it'll release iOS 12.1 to the public.
