Apple has just seeded the fourth beta of iOS 9.3.3 to developers and public beta testers for testing purposes, one week after seeding the third beta of iOS 9.3.3 and more than a month after the release of iOS 9.3.2, a minor bug fix update. iOS 9.3.3 has been in testing since May 23.
The update comes just one week after the third iOS 9.3.3 beta was released, suggesting that it may soon be ready for public launch. Don’t get too excited though. It’s mostly bug fixes, as Apple tries to tie up a few loose ends and turn its full attention to iOS 10.
As another minor 9.x.x update, iOS 9.3.3 features under-the-hood bug fixes and performance improvements to address issues unearthed since the release of iOS 9.3.2. No outward-facing changes or obvious bug fixes were discovered in the first three betas of iOS 9.3.3.
