After all, the beta version of iOS8.2 is also being pushed. Currently, some netizens have upgraded their devices to the beta version of iOS8.3. Let us take a look at some of the main changes. According to netizen fourist, since iOS8.3 and iOS8.2 are not in the same beta test series, users of iOS8.2 beta5 are temporarily unable to update to the iOS8.3 test version OTA. You must download the complete ipsw firmware file to upgrade. The discovered updates are as follows: 1. Supports 2/3/4G switching (China Unicom Hong Kong version iPhone6 ??Plus). Currently, some mobile users report that there is no switching switch. 2. The emoji keyboard has been updated. The new keyboard has a blurred background, supports sliding selection of categories, and the category icons have also been redesigned. 3. China UnionPay Apple Pay is supported. After testing, it is impossible to add credit card information in Passbook if the region is selected in mainland China. However, it can be added after changing the region information. It is not yet sure whether China UnionPay credit card can be added. Relevant options may appear when switching back to China settings, but a prompt will appear indicating that the operation failed. 4. CarPlay update: Now the iPhone can only be connected to CarPlay through the Lightning interface. The new system can be connected wirelessly, and Siri, Spotlight search, and Handoff will all be connected to it. 5. The Metal update adds more ways to use shaders. 6. iCloud Photo Library has removed the word beta, implying that it has become an official service. 7. The password input time interval can be changed in the iTunes Store and App Store settings options. This feature requires turning off the fingerprint payment function of the App Store and iTunes Store. It can be divided into those that require you to enter a password all the time and those that do not require you to enter a password within 15 minutes after entering the password. An additional option is whether a password is required for free projects, which is convenient for users. 8. The notification center plug-in drop-down crash bug still exists. 9. Operator version update. China Unicom has been updated to 18.1.2, and China Telecom has been updated to 18.2.1. In addition, according to netizen yaojing520: 10.
