Apple is going to begin seeding iOS 10.3 betas next week, reports Sonny Dickson. The noted tipster tweeted out over the weekend that iOS 10.3 beta 1 is currently scheduled to be released to developers on January 10 with an all-new 'Theatre' mode.
Dickson doesn't go into detail on exactly what 'Theatre' mode is, but does say that it will feature a popcorn-shaped icon in Control Center. It's possible this is a stealth mode of sorts, with either a dimmed display or dark UI assets for less distraction.
