An important nuance: on the Xiaomi Redmi Note 4, number locking works only for calls and SMS, but not for instant messengers (WhatsApp, Telegram, etc.). If you need to block a contact completely, you will have to do it separately in each application.

Why the blacklist doesn’t work: common problems

Sometimes users find that the lock is not working: calls keep coming and SMS messages come in as if nothing had happened.

Another common mistake is that users add a number to a blacklist but forget to save the changes. In MIUI 8/9, you must click "Done" or "Save" after adding a contact, otherwise the number will not be blocked. Also check if the settings are reset after updating the firmware, which often happens when you switch to a new version of MIUI.

How to check if the lock is working on your Redmi Note 4

Adding a number to a blacklist is half the battle, and you have to make sure that the locking actually works.

1. Test call: Ask a friend to call you from a locked number. If the call didn't pass (or dropped right away), the lock works. If the phone rang, check the settings (see table in the previous section).
2. SMS Check: Send SMS from a locked number. If the message does not arrive (or hit the Spam folder), the lock is active.

Log of calls

• Open the phone. → Journal → spamming.
• If there are records of blocked calls, the function works.

💡

If the locking doesn’t work after all the manipulations, the problem may be the firmware itself, in which case only flashing the phone to a newer version of MIUI (for example, from MIUI 9 to MIUI 11) will help.

What to do if the blacklist is reset after the update

After the MIUI update (especially if you are switching from MIUI 8 to MIUI 10+), the blacklist settings may reset, due to changes in the contact database structure, to restore the lock:

1. Export/import blacklist (if you have backed up): Open Settings → Additional → Backup and Reset. Select the backup created before the update and restore the data.
2. Manual number entry: If there is no backup, you will have to enter the numbers again (see the section "How to add a number").

Use of third-party applications

• Install Blacklist Plus or Truecaller – they save the settings regardless of the MIUI updates.

To avoid losing the blacklist in the future:

• 📋 Keep a separate list of blocked numbers in Google Keep or Notes.

⚠️ Note: If you are updating the Redmi Note 4 with MIUI 8 on MIUI 11+ through an unofficial firmware (e.g. xiaomi.eu), the standard blacklist may disappear altogether.
