Apple today released the third beta of an upcoming iOS 9.3.2 update to developers for testing purposes, one week after the release of the second iOS 9.3.2 beta and more than a month after the launch of iOS 9.3, an update that introduced Night Shift mode and other feature improvements. iOS 9.3.2 has been in testing since April 6.
iOS 9.3.2 beta 3 can be downloaded over-the-air using the beta configuration profile or through the Apple Developer Center.
iOS 9.3.2 is the second minor update to iOS 9.3, coming after iOS 9.3.1, an update that introduced critical bug fixes. iOS 9.3.2 appears to fix a major Game Center bug that has plagued some iOS users for months and it reintroduces the ability to use Night Shift and Low Power Mode simultaneously.
Aside from those tweaks, there appear to be no outward-facing changes, with the update focusing on under-the-hood improvements. Any new features or fixes found in the third beta will be listed below.
