Thanks to netizen Ji Yinkesi for submitting the clue! [Click here to go directly to the upgrade tutorial] According to news on July 2, Apple today pushed the iOS/iPadOS 17.6 Developer Preview Beta 2 update (Build Version Number: 21G5061c) to iPhone and iPad users. This update is separated from the last release. 14 days.
1. Apple typically runs two separate testing cycles each summer:
- Major new iOS update (rolling out in the fall)
- Last revision of the previous year’s update
- iPhone users currently have options One of the developer betas for iOS 18 and iOS 17.6, but only 1 can be running at the same time. Therefore, most beta users are likely to opt for iOS 18.
Apple iOS 17.6
Apple iOS 17.6 should be the last version of the iOS 17.x branch. The main updates are as follows:
- Introduced a new "Catch Up" function for the TV app, allowing users to watch highlights during the game even if they miss the start of the game.
Apple iOS 17.6 mainly focuses on fixing bugs, improving performance and improving stability in terms of system. According to public information, Apple has not announced new system features in iOS 17.6, but has fixed the following BUGs:
- Fixed the problem that some Bluetooth headsets may not be used as audio output paths under certain AVAudioSession configurations.
- Fix an issue where AVCaptureDeviceRotationCoordinator returns incorrect videoRotationAngleForHorizonLevelCapture and videoRotationAngleForHorizonLevelPreview values when using the front camera on iPad Air (6th generation) and iPad Pro (7th generation).
