Apple has made iOS 10.3.2 Beta 4 available to developers.
Apple hasn’t provided any specific details about what’s in iOS 10.3.2; it likely focuses on resolving bugs and smoothing over performance issues. Apple also made fourth betas of watchOS 3.2.2, macOS Sierra 10.12.5, and tvOS 10.2.1 available to developers. Apple hasn’t indicated if or when these new in-progress operating systems will be released to public beta testers.
Public betas typically drop a day or two after the developer betas. Consumers interested in testing pre-release software will need to register their Apple device, such as the iPhone 7, in order to receive beta builds of iOS and other platforms.
