While iOS 9.3.2 fixed a Bluetooth bug on the iPhone SE and the ability to use Low Power Mode and Nightshift at the same time, iOS 9.3.3 seems to be very minimal. Coming in at 1.4GB on several devices, the beefy update only lists "bug fixes and improvements" under its change log.
As every small update the Cupertino firm seeds to developers, the public build of iOS 9.3.3 should be too far out from making a public debut. As we know, Apple likes to push out the beta firmware to public beta testers a day or two after paid developer builds, expect to see that release Tuesday or Wednesday.
We'll keep you posted if we find anything new.
