Girls are harassed by text messages and phone calls from ex-boyfriends. Does the police station care?

It depends on the nature. If you are intimidated, harassed or threatened, you can call the police.

The general suggestion is to pull the black interception.

Open Tencent Mobile Manager-Harassment Interception-Call or SMS, or select the interception mode (such as black and white list) in the settings.

Through the "harassment interception" function, people who like to make phone calls at night can also be effectively intercepted, so that users can sleep peacefully. For those phone numbers that you don't want to answer, you can set them as "blacklist" so that the other party can't call your mobile phone.
