Apple Seeds Sixth Beta of iOS 10.2 to Developers and Public Beta Testers
Registered developers can download the sixth beta of iOS 10.2 from the Apple Developer Center or over-the-air with the proper configuration profile installed.
iOS 10.2 introduces new emoji, such as clown face, drooling face, selfie, face palm, fox face, owl, shark, butterfly, avocado, pancakes, croissant, and more.
There are more than a hundred new emoji, including several profession emoji available in both male and female genders, such as firefighter, mechanic, lawyer, doctor, scientist, and more. Apple has also redesigned many existing emoji, adding more detail to make them look much more realistic.
Along with new emoji, iOS 10.2 includes new wallpaper, new Music sorting options and buttons for Repeat and Shuffle, new "Celebrate" and "Send with Love" Screen Effects, an option for preserving camera settings, Single-Sign On support for watching live TV via apps, and the official "TV" app that was first introduced at Apple's October 27 event.
The TV app serves as an Apple-designed TV guide that aims to simplify the television watching experience and allow users to discover new TV shows and movies to watch.
The TV app is available on both iOS devices and the Apple TV (tvOS 10.1), and in iOS 10.2, the "Videos" app has been replaced entirely with the new "TV" app, which will now serve as the iOS TV and movie hub.
Apple has called iOS 10 its "biggest release ever" for iOS users, with a revamped lock screen, a Siri SDK for developers, an overhauled Messages app, a dedicated "Home" app for HomeKit users, new facial and object recognition capabilities in Photos, and redesigned Maps and Apple Music apps.
