1. Select wireless network and Bluetooth accessories directly from the control center.

Apple added a control center to iOS 7 for the first time, allowing users to perform some quick operations, such as turning on/off airplane mode, turning on/off cellular network, turning on/off Wi-Fi and so on. However, many controls only stay in the first-level menu and can only be turned off or on, and wireless networks and Bluetooth accessories cannot be directly selected. However, iOS 13/iPadOS officially opened this operation, and the selection of wireless network and Bluetooth accessories can be directly completed in the control center.

※ Press and hold the WLAN or Bluetooth icon to enter the secondary menu.

2. You can choose the information of picture protection when sharing.

IOS 13 and iPadOS have made many improvements to the sharing function, such as modifying the UI of the sharing list and adding sharing suggestions. One change is worth mentioning, that is, customizing the sharing content.

In the past, when we shared photos with others, we could only "choose > share > send", and the photos sent at this time were often a "complete photo". In other words, some information hidden in the photo will be collected together, such as location information and editing information, and if you share a live photo or a photo with portrait lighting effect, it will also contain live action and depth information.

Before iOS 13/iPadOS, you couldn't choose whether to share this information, but now the situation is unnecessary. IOS 13 and iPadOS have added "optional" to the sharing list, so you can choose whether to share the information in photos or not to avoid personal information disclosure.

3. Low data mode

You can understand "low data mode" as "low power consumption mode" of cellular data. After opening, the system will automatically reduce the network data usage of the App. This model may come in handy at the end of each month when the traffic is in a hurry.

※ low data mode: settings > cellular network >: cellular data options >; Low data mode

4.App supports independent setting language.

Before iOS 13/iPadOS, if you changed the default language of the system, most applications would use the same language. But now, each application's language supports independent settings.

※ Setup Path: Setup > App Independent Setup Page.

You can download large-scale applications through cellular network.

IOS 13/iPadOS has opened the traffic limit of cellular download app. Previously, only 150MB applications could be downloaded through the cellular network. Now you can turn on "Always Allow" in the settings to download applications via cellular data, provided that your transportation card can support it.

※ Setting path: Settings > ITunes Store and App Store & gt Cellular Data >: Download application.
