Apple iOS/iPadOS 17.6 developer preview beta released

Thanks to netizen Chike for submitting the clue! [Click here to go directly to the upgrade tutorial] According to news on June 18, Apple today pushed the iOS 17.6 developer preview beta update (build number: 21G5052e) to iPhone users. This update is 48 days after the last release.

Apple typically runs two separate testing cycles each summer, one for major new iOS updates rolling out in the fall, and one for typically the last revision of the previous year's update, and that's no different this year.

iPhone users can currently choose one of the iOS 18 and iOS 17.6 developer betas. Only 1 can be running at a time, so most beta users will probably opt for iOS 18.

According to public information, Apple has not announced new features of the iOS 17.6 system, and has only fixed the following BUGs:

1. Fixed that some Bluetooth headsets may not be used as audio output paths under certain AVAudioSession configurations.
2. 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).

The last major version of iOS 17, 17.5 last month, introduced the following new features:

• New Pride wallpapers
• Quartiles games for News+ users
• Offline Apple News content
• For the EU market Open Application Network Distribution
