It’s hard to pass judgment on iPhone’s new “theatre mode” because, well, it doesn’t exist out in the real world just yet. But according to a new report, that might be changing sooner rather than later, as Apple’s latest update is said to include this mysterious function. What is it, exactly? What does it do? Is this good news or bad news? Is the sanctity of the theatrical experience facing a new, insidious threat? Whatever it is, we’ll probably find out on January 10, when the iOS 10.3 beta rolls out to iPhone users.
