iOS 10 beta 6 is available as an over-the-air download to those who installed the first five betas or the beta configuration profile and it's available for direct download via Apple's Developer Center (developers only).
iOS 10 is a major iOS update with a ton of new features and design tweaks, including a new Lock screen experience with 3D Touch-enabled notifications, a more easily accessible camera, a redesigned Control Center, and a new widgets screen. According to Apple, iOS 10 is the company's biggest iOS update ever released.
The Messages app in iOS 10 has been overhauled with features that include background animations, bubble effects, Digital Touch, handwritten notes, Tapback replies, predictive emoji, and a dedicated App Store, and Photos has gained new facial and object recognition capabilities along with a Memories feature for rediscovering forgotten moments.
Over the beta testing period, Apple is tweaking the features introduced in iOS 10 to refine them ahead of the public release of the operating system. In iOS 10 beta 5, Apple introduced a new lock sound and fixed some important bugs.
According to Apple's release notes, iOS 10 beta 6 fixes a number of bugs. Search hints now function as expected in the Messages Store, Siri offers an appropriate response when a request requires a removed app, a bug that caused sticker pack apps to be blank has been fixed, and more. Reports from beta testers suggest an ongoing bug affecting the dock on iPads running iOS 10 has been resolved.
