After releasing yesterday the first Beta builds of its upcoming iOS 10.3.2, macOS 10.12.5 Sierra, watchOS 3.2.2, and tvOS 10.2.1 operating systems to registered developers, Apple now seeds iOS 10.3.2 Public Beta 1 to anyone else who wants to test drive it.
Including the same improvements and security fixes that Apple's iOS development team implemented in the iOS 10.3.2 Beta 1 build which application developers with an active Apple Developer account could download and install on their registered devices, the iOS 10.3.2 Public Beta 1 is out now and ready for installation.
Before you jump on the iOS Public Beta bandwagon, you should make a backup of your device using iTunes on macOS or Windows. Installing the iOS 10.3.2 Public Beta 1 release is as easy as accessing the Apple Beta Software Program on the iPhone, iPad, or iPod touch device you want to update.
Press on the blue "Download Profile" button and then install the iOS Beta profile from the settings page that will open on the device, after agreeing to the license agreement. When asked, restart the device, and after you enter your passcode, fire up the Settings app, go to the General section and access the Software Update entry.
You'll be able to see the iOS 10.3.2 Public Beta 1 update listed there, so press on the "Download and Install" button to install it. Your device will be automatically rebooted a couple of times for the new version to be installed. That's it, but please keep in mind that this is a pre-release version, not suitable for use on production devices
