Conflict of third-party applications

If you use call blocking apps (e.g. Truecaller, GetContact, Call Blocker), they may conflict with the built-in MIUI blocker to identify the culprit:

1. Verification of application permissions

Some apps may have access to a call log and block them without your knowledge to check:

  1. Press the power button before the off menu appears.
  2. Press and hold the item "Switch off (or turn off power)."
  3. Confirm the transition to safe mode.
  4. Try calling your phone – if there is no lock, one of the installed apps is to blame.

3. Removal of conflicting programmes

The most problematic applications:

  • 📱 Truecaller – often blocks numbers without notification.
  • 🔍 GetContact – can tag regular numbers as spam.
  • 🚫 Call Blocker – sometimes conflicts with the built-in blocker MIUI.
  • 🛡️ Kaspersky Mobile or Avast – antivirus with call blocking function.

If the problem has gone away after removing one of these apps, try to find an alternative or set it up more carefully.

💡

Before you delete the application, check its settings – it may be enough to turn off the call blocking function, rather than delete the program completely.

Resetting phone settings (extreme case)

If none of the above methods worked, the problem may lie in deep MIUI settings or corrupted system files, in which case a factory reset will help, but only if:

  • ✅ All incoming calls are blocked, including contacts from the phone book.
  • ✅ The problem persists after removing all third-party applications.
  • ✅ Flip-up or update MIUI didn't solve the problem.

How to reset your settings:

  1. Make a backup copy of important data (contacts, photos, messages).
  2. Go to Settings → About the phone → Reset settings.
  3. Choose Reset all settings (or Delete all data).
  4. Confirm the action and wait for the reboot.

⚠️ Warning: Reset will delete all data from the phone, including photos, messages and installed apps. If the phone is linked to a Mi Account account, after reset, you will need to enter a username and password.

If the reset didn’t help, the problem could be a hardware failure (e.g., a communication module malfunction).

What if the reset didn't help?
If the call lock is maintained after resetting the settings, the reasons may be as follows: 1. SIM-cards - try to replace it with a new one from the operator. 2. Firmware problems - you may need to reflash the phone through the Mi Flash Tool. 3. Hardware failure - a malfunction of the antenna or communication module (diagnosis is required in the service). 4. Operator blocking – sometimes operators block incoming calls by mistake (you need to call in support).

  • 🔄 Update regularly MIUI — New versions fix errors related to blocking calls.
  • 📋 Check the blacklist after installing new spam blocking apps.
  • 📡 Watch the operator’s services – sometimes they plug in spam protection without your knowledge.
  • 🔍 Use one locking app – multiple blockers may conflict.
  • 📱 Test new ones SIM-Cards – if you buy a new SIM, check if the operator blocks incoming calls by default.

If you often experience blocked calls, keep a log of which numbers are blocked, at what time and under what circumstances, which will help you identify the cause faster.
