Is there a mobile phone software that can block information showing incoming calls or some numbers?

Mobile phone software can completely hide the incoming calls and information of private contacts.

Many mobile phone softwares are like this. I suggest you install Tencent Mobile Manager in your mobile phone. In Tencent's mobile phone housekeeper, the private space can encrypt the short messages and call records of designated private contacts to ensure privacy.

These encrypted SMS messages and call records will only be displayed in Tencent's mobile phone housekeeper, and no records will be left in the SMS inbox and call records. So even if someone peeks at your phone, they can't see it.

Yes, mine is a QQ address book, which can backup Unicom people synchronously. Better than the phone itself. Open the contact settings to see the display number and attribution. Whether it's an incoming call or a phone in the address book, you can display the place of attribution, and you can log in with a QQ account, and there are many practical functions.
