How Lockdown Mode protects your device --> About Lockdown Mode - Apple Support (IN)
When Lockdown Mode is enabled, some apps and features will function differently, including:
- Messages – most message attachment types will be blocked, other than certain images, video and audio. Some features, such as links and link previews, will be unavailable.
- Web browsing – certain complex web technologies will be blocked, which may cause some websites to load more slowly or to not operate correctly. In addition, web fonts may not be displayed, and images may be replaced with a missing image icon.
- FaceTime – incoming FaceTime calls will be blocked unless you’ve previously called that person or contact. Features such as SharePlay and Live Photos are unavailable.
- Apple services – incoming invitations for Apple services, such as invitations to manage a home in the Home app, are blocked unless you have invited that person previously. Game Center is also disabled.
- Photos – when you share photos, location information is excluded. Shared albums are removed from the Photos app, and new Shared Album invitations are blocked. You can still view these shared albums on other devices that haven’t enabled Lockdown Mode.
- Device connections – to connect your iPhone or iPad to an accessory or another computer, the device needs to be unlocked. To connect your Mac laptop with Apple silicon to an accessory, your Mac needs to be unlocked and you need to provide explicit approval.
- Wireless connectivity – your device won’t automatically join non-secure Wi-Fi networks and will disconnect from a non-secure Wi-Fi network when you turn on Lockdown Mode. 2G mobile support is turned off.
- Configuration profiles – configuration profiles can’t be installed, and the device can’t be enrolled in Mobile Device Management or device supervision while in Lockdown Mode.
Phone calls and plain text messages will continue to work while Lockdown Mode is enabled. Emergency features, such as SOS emergency calls, will not be affected.
