The performance of short messages being hacked

Some Android phones will be reminded to intercept short messages received from blacklisted mobile phone numbers. If the other party clicks the notification to enter the SMS application, you can see the content of the SMS, but even if the other party checks it, you won't receive a reminder. This is because the mobile phone blacklist is not intercepted on the operator's server, but the interception mechanism of the mobile phone itself, which only chooses to block the reminder after receiving the blacklisted phone number or SMS.

When a user calls you, if he is on your blacklist, your mobile phone will send a prompt message to the mobile, and the mobile will return this prompt message to the dialing user, usually for the user who is busy or on the phone. People on your blacklist can still make calls, but your mobile phone automatically refuses to answer.
