One of the advantages of Apple having full control over its iOS ecosystem is bug fixes can arrive pretty quickly. A new fix released in version 10.0.2 resolves an issue with Lightning headphone controls getting disabled after a period of inactivity. This bug was reported soon after the iPhone 7 launch last week. And thankfully, Apple addressed the issue rather quickly. The physical controls on the Lightning-connected headphones and earbuds should continue working even after you’ve stopped listening to anything for a while.
Aside from that, this update fixes two other issues: one is regarding Photos closing or quitting when some users switch on iCloud Photo Library and another is regarding “an issue that prevented enabling some app extensions.
