Apple Releases First iOS 10.2 Beta to Public Beta Testers With New Emoji, Wallpapers and More
Beta testers who have signed up for Apple's beta testing program will receive the iOS 10 beta update over-the-air after installing the proper certificate on their iOS device.
Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to both iOS and macOS Sierra betas. Betas are not stable and include many bugs, so they should be installed on a secondary device.
iOS 10.2, as a major 10.x update, includes several new features to enhance iOS 10. New emoji have been added, introducing Unicode 9 characters like clown face, drooling face, selfie, face palm, fox face, owl, shark, butterfly, avocado, pancakes, croissant, and more, plus many profession emoji available in both male and female genders.
Apple has also updated the artwork on many existing emoji, adding detail and making them look less cartoonish and more realistic. In addition to new emoji, the 10.2 update includes new wallpaper, new Music sorting options, a new "Celebrate" Screen Effect," an option for preserving camera settings, a Videos widget, and more.
