After releasing the second beta a week ago, Apple today seeded developers and public beta testers with the third build of iOS 10.3.2 for testing on the iPhone, iPad, and iPod touch. If your device is registered to receive beta builds, head over to Settings > General > Software Update. Tap “Download and install” next to the iOS 10.3.2 Beta 3 listing and you’ll be good to go. I recommend jumping on a Wi-Fi network first alongside plugging in your device beforehand as a) you don’t want data overcharges on your bill and b) you don’t want your phone or tablet to die during the installation process.
Since iOS 10.3.2 is a cumulative update, there’s only bug fixes and under-the-hood improvements on their way to users. However, if you find something different not noted here, email us at firstname.lastname@example.org or hit us up on Twitter @MBEDDEDMaximum.
