Why does Xiaomi's mobile phone need to be unlocked after it is turned on to receive the prompt?

When your Xiaomi phone has to be unlocked after it is turned on to receive the prompt, it may be because your phone is set with the "system lock" function.

In the system lock mode, the screen will be locked after the phone is turned on, and the user is required to enter a password or fingerprint to unlock it. In this case, the user must unlock the phone to receive the prompt.

If you don't want to lock the screen after turning on the phone, you can turn off the "System Lock" function in the phone settings.
