Hello, welcome to the Elsevier Assistant, which is used by 200 million iPhone users.
Apple today pushed the iOS / iPadOS 15.3 Developer Preview Beta2 update (build number: 19D5040e) to iPhone and iPad users, which is 3 weeks after the last release.
Apple officially did not give the content of the explanation, but there is a statement change. When a user's cellular or WiFi network disables the iCloud Privacy Relay service, Apple clarifies that when it is turned off, it's not always because of a lack of carrier support.
In iOS 15.2 and previous iOS 15.3 betas, if the iCloud Privacy Relay service was disabled due to a cellular plan, Apple put all the blame on the carrier.
It's unclear what new features are added to iOS 15.3 and iPadOS 15.3.
iOS / iPadOS 15.3 Preview Beta2 supports the following devices:
iPhone:iPhone 13 mini、iPhone 13、iPhone 13 Pro/Pro Max、iPhone 12 mini、iPhone 12、iPhone 12 Pro/Pro Max、iPhone 11、iPhone 11 Pro/Pro Max、iPhone XS、iPhone XS Max、iPhone XR、iPhone X、iPhone 8/8 Plus、iPhone 7/7 Plus、iPhone 6s/6s Plus、iPhone SE/SE 2;
iPad:iPad Pro 1/2/3/4/5(12.9)、iPad Pro 1/2/3(11)、iPad Pro(10.5)、iPad Pro(9.7)、iPad Air 2/3/4、iPad 5/6/7/8/9、iPad mini 4/5/6;
iPod Touch：iPod Touch 7。
iOS / iPadOS 15.3 Preview Beta2 upgrade method:
1. To prevent unexpected situations, before upgrading, back up all data in your device in advance.
2. After upgrading, it is not possible to downgrade back to the iOS version that Apple has officially turned off verification.
