Apple has started rolling out the fourth beta version of the iOS 9.3.2 to developers over iPhones, iPads and iPod touch devices. The company is also seeding the fourth beta versions for OS X 10.11.5 to Macbooks and tvOS 9.2.1 to Apple TVs.

Like the previous beta versions of iOS 9.3.2, the beta 4 update also does not introduce any new features and just addresses bug fixes. Of the major fixes the most important is a Game Center bug that had been plaguing iOS devices for a while now.

Prior to this in the iOS 9.3.2 beta 2 update Apple had brought back the Low Power Mode and its simultaneous use with the Night Shift which remains intact. iOS 9.3.2 beta 4 can be downloaded over-the-air using the beta configuration profile or through the Apple Developer Center.

The update is available only for registered developers for now but will in a day or two be accessible to public testers as well. Once your device is updated to iOS 9.3.2, it cannot not be restored to any earlier versions of iOS.

Apple had released iOS 9.3 to the public in March introducing new features like Night Shift, Touch ID secure Notes and better education features for iPad. A major bug related to the Safari browser had, however, plagued iPhones and iPads after users installed the update. Apple thus had to release another update soon after in the form of iOS 9.3.1 to fix the bug in the previous update.

Similarly, for the OS X 10.11.5 and tvOS 9.2.1 beta 4 versions, there are no major updates and only bug fixes. The company is unlikely to release any major software changes to these platforms until the WWDC in June where it is speculated that new versions of iOS, OS X, tvOS and WatchOS will be unveiled.
