How to enable auto call on Xiaomi with MIUI 12: the complete guide

The auto dial feature on Xiaomi’s MIUI 12 smartphones allows you to automatically retry dialing if you’re busy or not responding, which is especially useful in situations where you need to urgently contact someone but the line is constantly busy, but many users face a problem: newer versions of the firmware have a deeper option than before, and some models do not have it at all in the standard settings.

In this article, we will look at where exactly the auto dialer in MIUI 12 is, how to turn it on on different Xiaomi models (including Redmi Note 10, Poco X3, Mi 11 and others), and also look at alternative ways to activate the function if it is not on the menu.

Where is the auto dial in MIUI 12: the official way

Most MIUI 12 firmware has an auto dialer integrated into the standard Phone app, but its location depends on the firmware version and regional build, and this is the basic path for most devices:

1. Open the Phone app (the tube icon on the home screen).
2. Press three points (⋮) top-right.
3. Select the Settings item.
4. Go to the section Additional or More (on some models - Calls).
5. Find the option Auto dial or Automatic re-set.

If you have a global version of MIUI (e.g. MIUI 12.5 Global), the path may be: sometimes the option is hidden in Settings → System Applications → Phone → Additional. On Chinese firmware (e.g. MIUI 12 China), the feature may not be available at all – we will talk about this below.

💡

If your phone doesn’t have an “Autophone” option in its settings, try updating the Phone app via Google Play. On some Xiaomi models, the feature only appears after the update.

Step-by-step instructions for the inclusion of an auto dial-up

Once you have found the partition you want, you just have to activate the function and configure the settings. Here's a detailed instruction:

1. Activation of the function: 📱 Switch the slider AutoDirector to the position on.. 🔄 If there is no slider, click on Automatic Re-Director and select Included.
2. Setting the interval: ⏱️ Set the interval between attempts (usually available options: 5, 10, 15, 30 seconds). 🔢 Select the number of attempts (maximum – usually 5 or 10 times).

Update the Phone app to the latest version|

Check that you have global firmware (not China ROM) |

Make sure the function is not blocked by the operator |

Restart your phone if the settings do not apply-->

On some devices (such as the Poco F3 or Redmi K40), an option to Use Contacts Only appears after activating the auto dial, and if activated, the feature will only work when calling subscribers from the phone book, ignoring unknown numbers.

Why the phone is not available in MIUI 12

If you didn't find the auto dial feature in the settings, there could be several reasons.

• 🌍 Regional firmware: On Chinese versions MIUI (China ROM) Auto dialing is often missing due to local regulatory constraints, so the solution is to reflash the phone to a global version.
• 📱 Device model: On some budget models (e.g. Redmi) 9A POCO C3) The function can be reduced by the manufacturer.
• 📞 Phone app version: If the app is outdated, the option may not show up.Update it via Google Play.
• 📡 Operator restrictions: Some mobile operators (e.g. Tele2 or Iota) block auto dialing at the network level.

Important: On devices with MIUI 12.5 firmware and later, the auto dial function can be moved to the Phone app's "Special Features" section. If you don't find it in the standard settings, check this section.

Alternative ways to include auto dial-up

If the standard method didn't work, you can use workarounds. Here are three proven options:

1.Use of the USSD code

Some operators support the activation of the auto dial through USSD-Try typing the phone in the phone app the following combinations:

*43# - turn on auto dial (works on MTS, Beeline, MegaFon)


#43# - Disable the auto dial




*43* number # - include for a specific subscriber

If a notification of successful activation appears after code typing, the function will work at the network level, even if it is not in the phone settings.

Third-party annexes

There are several apps on Google Play that emulate auto dialing, the most popular being:

• 🔄 Auto Redial – simple interface, support for blacklist numbers.
• 📞 Redialer: Auto Call Back - Flexible interval settings and number of attempts.
• ⚡ Quick Redial – works without root rights, minimalist design.

3. Customization through the engineering menu

For power users, there's a way to turn on auto dialing through the engineering menu. Careful: wrong actions can disrupt the phone!

1. Open the Phone app and type ##4636##.
2. Go to the phone information section.
3. Scroll down and find Automatic Redial (also known as Auto Redial Setting).
4. Set the Enabled value and save the changes.

⚠️ Warning: The engineering menu contains critical system settings. Do not change other settings unless you are sure of their purpose.

Table of compatibility of auto dialing with Xiaomi models

Not all Xiaomi devices have the same auto dialing function, and below is the compatibility table for popular models with MIUI 12:

If your model is not in the table, try updating your firmware to the latest version of MIUI 12.5 or later – sometimes the feature appears after an update.

Frequent problems and their solutions

Even after activation, the auto dialer may not work correctly, and let's analyze the typical errors and ways to fix them:

• 🔕 Function not activated: Check if it is blocked by the operator (type *#43# for diagnostics). Delete the cache of the phone application in the settings (Settings) → Annexes → Application management → Phone. → Clear the cache).
• ⏳ The dial time is too long: Set a minimum (5 seconds) in the auto dial settings. If the option is inactive, use a third-party app (e.g. Auto Redial).
• 📵 Auto dial only works once: Check that the number of attempts is set more than 1. Restart the phone - sometimes the settings of the communication module are confused.

⚠️ Attention: On some firmware MIUI 12 Auto dial conflicts with Recording Conversations. If both options are on simultaneously, there may be failures.
