How to permanently disable auto dial on Xiaomi Redmi Note 9: a detailed guide

Auto dialing on Xiaomi Redmi Note 9 smartphones is one of those features that can both save in an emergency and become a source of irritation. Users often find that the phone automatically calls back to the last number after a call is reset — whether it is a casual tap or an interrupted conversation. In some cases, this behavior is associated with the operation of the MIUI brand shell, in others, with the settings of the SIM card or third-party applications.

In this article, we’ll look at all the ways you can disable auto dialing on the Redmi Note 9, including hidden system settings that aren’t obvious at first glance. You’ll learn how to check your current settings, which apps can affect the feature, and what to do if standard methods don’t work.

Why the smartphone automatically calls back: the main reasons

Before you start disabling your auto dialer, it’s important to understand what’s causing it. On the Xiaomi Redmi Note 9, this feature can be activated for several reasons:

• 🔄 Corporate function MIUI: Some firmware versions include the "Auto-Call" option, which works when short conversations or communication failures are triggered.
• 📱 SIM card settings: Mobile operators (for example, MTS, Beeline) sometimes activate the auto dialing service at the network level.
• 🤖 Third-party apps: Messengers like WhatsApp or Viber, as well as some dialers (like Truecaller) have their own re-typing mechanisms.
• 🔧 Communication module failures: If the phone frequently loses network, the system may automatically attempt to restore connection.

Interestingly, on the Redmi Note 9 (models M2003J15SC/M2003J15SS), auto dialing is most often associated with the operation of the standard Phone application from Xiaomi. In newer versions of MIUI 12+, this feature can be hidden deeper in the settings than in MIUI 11.

⚠️ Note: If the auto dial is only for a specific number (such as a bank or operator), first check if you have a paid subscription to such a service.

Method 1: Disabling the auto dial in the standard "Phone" application

The most obvious and safe method is to use the built-in settings of the Phone app. On the Redmi Note 9, the path to these may vary depending on the version of MIUI, but the general logic is maintained:

1. Open the Phone app (the tube icon on the home screen).
2. Click on the three dots in the top right corner and select Settings.
3. Go to the Calls section or additionally (in) MIUI 13+ may be called Call Services).
4. Find the AutoCall, Automatic Repeat or Last Number Repeat option and turn off the slider.

If you don’t have this option, try an alternative route:

Settings → Applications → Application Management → Phone → Permissions → Additional settings (if any)

On some firmware (e.g. MIUI Global 12.5), the auto dial option may be hidden, in which case resetting the phone application will help:

Settings → Applications → Application Management → Phone → Storage → Clear data

⚠️ Attention: Clearing the data of the phone application will delete the call history! Pre-export it if it is important. → Journal → ⋮ → Exports.

Method 2: Checking the services of the mobile operator

If the auto dial occurs even after all settings in the phone are turned off, the problem may be on the operator’s side. Many Russian providers (for example, Tele2 or MegaFon) offer the service “Autodale Call” or “Re-Dialing” in the tariff plans, to turn it off:

• 📞 Dial a combination for service management: MTS: *111*46# (Checking of active services: *110*09# MegaFon: *105*400# Television2: *155*1#
• 💬 Send. SMS with the text of STOP or OTKL to a short service number (check it with the operator).
• 🌐 Go to the personal account on the operator's website and check the section "My services".

If you use a virtual operator (such as Yota or Tinkoff Mobile), contact support – they may have their own auto dial control mechanisms.

💡

If the operator’s auto dialer still works after the service is turned off, try temporarily inserting the SIM card into another phone (for example, an iPhone or Samsung) and checking the behavior, this will help determine whether the problem is in the SIM card or in the settings of the Redmi Note 9.

Method 3: Disconnect via the Engineering Menu (for advanced users)

If standard methods don’t work, you can try turning off auto dialing via an engineering menu (also known as MTK Engineer Mode or Qualcomm Service Menu), which is only suitable for power users, as incorrect changes can disrupt the communication module.

Instructions for Redmi Note 9 (MediaTek Helio G85 processor):

1. Open the Phone app and type the combination: ##4636## Some firmware may work ##8255## or ##36446337###.
2. In the menu that opens, select Phone Information (or Phone Information).
3. Scroll down to Auto redial or Auto retry and turn off the option (if it is active).
4. Press Menu (three dots) and select Update configuration to save the changes.

For models with a Qualcomm Snapdragon processor (such as the Redmi Note 9 Pro), the combination may be different:

##7378423##

In the menu of Service tests → WCDMA → Auto redial.

⚠️ Warning: Changes to the engineering menu may result in a loss of warranty or unstable network performance.If you are not sure about your actions, it is better to contact the Xiaomi service center.

Method 4: Using third-party applications to manage calls

If the built-in MIUI means do not allow you to disable the auto dial, you can use third-party applications, they intercept outgoing calls and block automatic retry.

• 🛡️ Truecaller - has the function of blocking unwanted calls and managing auto dial. After installation, go to Settings → Lockdown → Additionally.
• 📱 Call Blocker allows you to create rules for repeated calls. In the settings, select Rules → Stop the auto dialer.
• 🔄 Auto Redial Stopper is a specialized application to disable autorecall. It works at the system level (requires permission to access calls).

Before installing, check the application permissions:

Settings → Applications → Permissions Management → Phone

Disable access to calls for unreliable programs.

Important: Some applications (such as Truecaller) may conflict with the standard MIUI dialer. If you have problems with outgoing calls after installation, try:

Settings → Applications → Default → Phone App → Select “Phone”

💡

Third-party auto dial-locking apps may consume additional battery due to background work. Regularly check charge consumption in Settings → Battery → Battery Use.

Method 5: Reset network settings (last resort)

If none of these things work, the last thing you can do is reset your network settings, and it will bring all the connectivity settings (including Wi-Fi, Bluetooth, and mobile) back to factory values. On the Redmi Note 9, it's done this way:

1. Go to Settings → System → Additional → Resetting settings.
2. Select Network Reset (not to be confused with a full reset!).
3. Confirm the action by entering PIN-code.
4. After the reboot, check if the auto dial problem persists.

This method removes:

• Saved Wi-Fi networks and their passwords.
• Coupled Bluetooth devices.
• Mobile network settings (including APN)
• VPN and proxy settings.

⚠️ Note: After a network reset, you may need to reset the Internet (especially if you use Yota, Tinkoff Mobile or other virtual carriers). APN Or check them with the operator.

What to do if the auto dialer still works?

If after all the manipulations the problem persists, it may be related to:

• 🔄 Hardware failure: Communication module malfunction (especially if the phone fell or got wet).
• 📱 Firmware: On some custom ROM (Pixel Experience: Auto dial function works differently.
• 🛠️ Viruses: Malware can simulate auto dial to write off funds.

Actions in such cases:

1. Check your phone for viruses with Malwarebytes or Dr.Web Light.
2. Update your firmware to the latest version of MIUI: Settings → About Phone → System Update
3. If you suspect a hardware malfunction, contact the service center. For the Redmi Note 9, Xiaomi official centers are in most major cities.

If you are sure that the problem is software, you can try a factory retracement (with a complete data cleanup).
