iOS 10.3.2 beta 1 was released for iPhone and iPad just one day after the official version of iOS 10.3 was released to users worldwide. iOS 10.3.2 beta 1 can be installed right now by all application developers for the iOS platform, the American company currently offering only this build for users.
For now, we do not know what news iOS 10.3.2 beta 1 brings for iPhone, iPad and iPod Touch, but we are probably talking about minor changes offered by Apple. This is an interim update, so iOS 10.3.2 beta 1 should come with not too many changes for iDevice users around the world, and we shouldn't expect too much.
Apart from iOS 10.3.2 beta 1, Apple also released the first beta versions of tvOS 10.2.1, macOS 10.12.5 and watchOS 3.2.2.
