A pop-up window appeared on the screen of a colleague's iPhone 14 just now, prompting: "Family" wants to send you an important warning. Even if the iPhone is muted or "Do Not Disturb" is turned on, the important warning will always play a sound and display on the lock screen, no matter whether you click "Allow" or "Don't Allow", the iPhone screen is unresponsive and cannot be accessed into a normal phone interface.
Encountering this kind of problem, the only way is to force restart the phone , method: press the volume ➕ once, then press the volume ➖ again, and then press and hold the power button until the apple turns bright white, then release it.
To avoid this problem from happening again, remember to turn off important warnings in [Settings] - [Notifications] - [Family].
