Apple today released the first official update (10.0.2) to the iOS 10 operating system, just 10 days after releasing it to the public and a week after the new iPhones went on sale in the US. The update includes fixes for several minor bugs, including an annoying problem that was causing the Lightning headphone controls to be disabled after a period of inactivity.

The glitch seemed to happen randomly and could only be fixed by unplugging and re-plugging them. Reports started to emerge just days after the iPhone 7 and iPhone 7 Plus officially went on sale and to Apple’s credit the fix didn’t take too long at all.

The update also solves a problem that caused the Photos app to crash when enabling iCloud Photo Library and a problem that prevented app extensions from being enabled.

In related news Apple yesterday delivered the first iOS 10.1 beta, which will add support for the much hyped new ‘Portrait’ mode that the company discussed extensively during the iPhone 7 launch. The feature makes use of the dual camera system on the iPhone 7 Plus to calculate depth and simulate bokeh (background blur) in portrait shots.

The effect more or less resembles what you’d get using a DSLR or mirrorless camera, though of course it’s not the same as the real deal. Both Huawei and HTC have attempted something similar with their dual-camera smartphones as well.

iOS 10.1 is only available as a public beta but it shouldn’t be too long before the stable release.
